In this investigation, a biocomposite was fabricated using recycled polypropylene (RPP) reinforced with oyster shell (OS) particles. The introduction of OS bio-fillers is aimed to mitigate plastic shrinkage during the injection molding process, with two different proportions employed: 10wt.% and 30wt.%. The biocomposite was characterized thermally and mechanically. Thermal analysis by TGA showed that the bio-fillers increased the degradation temperature of the recycled polypropylene biocomposite. Mechanical assessments demonstrated an enhancement in polypropylene stiffness by 10.4% and microhardness by 21.1%, albeit at the cost of reduced ductility. Conversely, the tensile strength and impact resistance decreased slightly with the incorporation of OS particles in RPP. Dynamic mechanical analysis indicated an improvement in the storage modulus up to 1.45 GPa of the biocomposite with the reinforcement of OS particles. These findings underscore the potential for integrating recycled polypropylene with natural reinforcements, aligning with the global pursuit of environmentally sustainable materials in diverse industrial applications.","PeriodicalId":508263,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141921145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research addresses challenges related to achieving consistent mass across lattice structures due to manufacturing parameters. Discrepancies in flexural rigidity and compression behavior among the produced models trigger an exploration into the influence of design factors. The study reveals significant insights into the mechanical properties of six complex lattice structures produced through FDM 3D printing. The Tetrahedron-Cubic lattice stands out with superior bending rigidity at 15.36 N/mm, and variations in performance are attributed to layer orientation and material anisotropy. Specific energy absorption reaches its peak in the Tetrahedron-Cubic lattice at 38.54 J/g. These conclusive results provide considerations for future design and optimization.

Our study aims to investigate specific plaster properties while reducing the rate at which end-of-life plastic is rejected in nature. This manuscript explores a gypsum composite reinforced with plastic waste (GPPS), with an emphasis on thermo-physical, chemical, and mechanical characteristics. Ten samples were produced, with varying addition rates (0%, 5%, 10%, and 15%) by weight of GPPS waste, incorporating three different sizes of GPPS aggregates (δ ≤ 1 mm; 1 mm < δ ≤ 1.25 mm; and 1.6 mm < δ ≤ 3 mm). The results demonstrate that the gradual increase in the quantity of GPPS aggregates incorporated into the plaster matrix produced a notable enhancement in thermal properties. However, this resulted in a slight decrease in mechanical performance due to a loss of workability. In general, the material evolution indicated that the inclusion of 15% size 2 GPPS was concluded to be the optimal arrangement for effectively reducing both thermal and mechanical qualities. Specifically, density, conductivity, and thermal diffusivity were decreased by approximately 20.73%, 42.47%, and 53.57%, respectively, while compressive strength decreased by 15.73% (6.64 MPa), a tolerable value according to the EN 13279 standard.","PeriodicalId":508263,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"13 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141926037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Present paper has been focused on investigating the strain rate effects on mechanical properties of pristine nylon-6 and 20% glass reinforced nylon-6 material fabricated using injection molding and SLS (Selective Laser Sintering) printing manufacturing methods, respectively, at three strain rates of 0.0003, 0.003, and 0.01 per second. Tensile strength of injection molded nylon-6 has shown a positive relationship with strain rate whereas compressive strength has shown a reciprocal effect. At highest strain rate of 0.01 s−1, tensile strength exhibits 10.27% more as compared to lowest strain rate of 0.0003 s−1. Tensile strength at highest strain rate is found 60 MPa whereas at lowest strain rate it exhibits 54.41 MPa. At higher values of strain rate, rising of maximum strain is found very much sensitive than the rise in tensile strength. It also shows high percentage of deformation at higher value of strain rate. On the other hand, SLS printed 20% glass reinforced nylon-6 shows variable tensile strength with respect to strain rate due to uneven distribution of glass particles into nylon matrix created due to manufacturing process of SLS printing. FESEM images shows the cavity formation as observed before loading conditions whereas the glass fracturing phenomenon observed at the after loading conditions. However, compressive strength is found minimal with strain rate with an average value of 175.61 MPa. The findings of this study have contributed in avoiding the improper selection of material and its strain rate application during numerical modeling for industrial application purpose.","PeriodicalId":508263,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"23 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140674204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the cutting process, the Ra local oscillation phenomena takes place; that is, surface roughness seems to grow, decrease, and then increase as the cutting depth increases within a particular cutting depth range while maintaining the same cutting speed and feed. To find out why this behavior occurred, a cutting experiment and a simulation analysis of SiCp/Al composites were performed. Tests were conducted to find out how varied cutting depths affected surface roughness, and a finite element model for two-dimensional cutting was created. Based on the data, it can be concluded that Ra’s local oscillation phenomena is responsible for the surface quality at various cutting speeds. At 100 mm/s, 200 mm/s, 300 mm/s, and 400 mm/s, respectively, the mutation’s surface quality improved by 29.6%, 14.3%, 19.6%, and 30.7% prior to the cutting depth. The analysis is justified by the fact that the depth of cut is increasing, the way in which particles are removed has changed and the percentage of scratches appears to be decreasing. As aluminium is a plastic material, plastic deformation occurs during cutting by the sub-cutting edge of the extrusion, coating the machined surfaces and producing fine cracks rather than plough furrows. In a sense, increasing the cutting thickness results in larger chips, more force on the particles in the cutting path and easier removal. At the same time, it reduces the width of the chip in future cuts, improving the surface quality of the process.","PeriodicalId":508263,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"80 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140677166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, prolonged exposure to a hygrothermal environment can compromise the mechanical integrity of composite joint structures. In this paper, accelerated aging experiments were designed to test the mechanical properties of CFRP after hygrothermal aging, a novel mechanical property prediction model tailored for the hygrothermal coupled environment is presented. The model accurately predicts the modulus and strength of CFRP after hydrothermal aging. A three-dimensional finite element model for the CFRP interference riveted structure, considering a tri-coupled state of moisture, temperature, and force was established by the application of subroutine and field superposition. The precision of this finite element model has been affirmed through accelerated aging tests. By integrating finite element analysis with experimental methods, this research delves into the failure modes and mechanisms of CFRP and its joints under hygrothermal conditions. It was discerned that the hygrothermal environment undermines the bond between fibers and the matrix, resulting in pronounced interlaminar delamination and shear failure in CFRP. The failure forms gradually change from “flaky” at lower levels of aging to “filamentary” at higher levels of aging. For CFRP riveted structures, the hygrothermal conditions influence their loadbearing capability and shift the primary positions of failure.","PeriodicalId":508263,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"75 S7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140709473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon nanotubes (CNTs) have remarkable mechanical, physical, and thermal properties. Adding them to the resin is a promising solution and makes it possible to manufacture cost-effective products with enhanced engineering properties. Our study investigated the chemical functionalization of multi-wall carbon nanotubes (MWCNTs) through acid oxidation to evaluate the durability-related properties of vinyl-ester-based nanocomposites. Samples containing 0.1 wt% of as-received CNTs and functionalized CNTs were characterized by scanning electron microscopy (SEM), elemental analysis, and X-ray photoelectron spectroscopy (XPS). A small amount of two dispersing agents (BYK 104S and BYK 9076) was added to the mixtures to produce high particle stability in the nanocomposites. Barrier properties and moisture diffusivity were determined by immersing samples in a water bath at 50°C. Aging was conducted by fully immersing samples in NaOH solution at 50°C. Matrix degradation was assessed with tensile tests, dynamic mechanical analysis (DMA), and differential scanning calorimetry (DSC) before and after conditioning. The results indicate that the addition of oxidized CNTs significantly improved the mechanical, physical, and durability properties of the composites. Additionally, unlike nanoclay-based nanocomposites, oxidized CNTs do not increase water absorption at saturation.","PeriodicalId":508263,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"37 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140368134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article fabricated thermoplastic composite joints with varying end configurations and compared them with metallic rivet joints. Emphasizing the convex form, diverse multi-rivet links were crafted for single-lap tensile samples. Integrating tensile tests and strain gauge measurements, this research explored load distribution patterns across diverse rivet quantities and assessed the impact of size on distribution. Furthermore, finite element software was used to dissect the load distribution patterns and failure mechanisms in the multi-riveted connection structure. Drawing from experimental findings, convex GF/PP rivets exhibited an 18% higher tensile load than metallic ones, with a simultaneous 32% weight reduction. In multi-rivet connections, end rivets demonstrated higher load-bearing capacity. Enhanced spacing and plate width improved load distribution, elevating joint load capacity by 7% (spacing 25 mm to 55 mm) and 6% (width 30 mm to 55 mm).
