This article profusely analysed the various techniques for ameliorating the performance of composite joints, such as bonding methods (secondary bonding, co-bonding, co-curing, and multi-material bonding), surface modification techniques (plasma, laser surface treatment, surface grinding, etc.), additional reinforcement techniques (Z pin, wire mesh, nanofiller, etc), and different joint geometries (stepped joints, half-stepped joints, balanced joints, and scarf joints). Also, the effect of various adhesives and fabrication techniques on the static and dynamic performance of CFRP and GFRP-based joints was studied in detail. Moreover, this review addresses the finite element modelling and optimisation techniques on adhesively bonded joints. It has been observed that the bonding methods, surface modification to enhance the roughness of the adherend, addition of nanofillers, and variations in joint geometry greatly influence the shear strength, fracture toughness, fatigue, and vibration behaviour of FRP composite joints.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"71 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140808990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interfacial bond deterioration and stress transfer mechanisms have been investigated in the present study by employing acoustic emission (AE) monitoring in hinged-type GFRP-reinforced concrete (GFRP-RC) beam specimens. The bond strength of the test specimens, governed by chemical adhesion, mechanical interlocking, and frictional resistance, has been intricately examined. Various AE signal parameters as well as historic and severity indices derived from the AE signal parameters have been meticulously evaluated and correlated with bond stress and rebar slip variations. The present study has also introduced an innovative approach of using the sentry function for the assessment of bond deterioration and associated mechanisms. The results of the present study demonstrate the reliability of AE parameters in monitoring debonding and bond strength variation, the effectiveness of the sentry function in evaluating damage progression, and the utility of historic and severity indices in capturing micro-mechanism transformations. The accurate localization of debonding and the qualitative distribution of bond stress have also been demonstrated by through correlations between cumulative AE parameters and rebar slip, Additionally, the present study also highlights the significance of peak frequency variations in AE signals, serving as a crucial tool for quantifying the mechanical interlocking and interfacial friction. The results contribute significantly to precise assessments and development of effective strategies for mitigating bond deterioration in GFRP-RC elements.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"10 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140805446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exhaustive experimental investigations have been carried out with different salinity levels (0%, 2.5% and 5%) and exposure periods (45 days to longer time periods (>1 year)) to determine the influence of the same on the mechanical property degradation of epoxy polymers. The effect of degraded properties on the performance degradation of bonded epoxy composite systems in terms of damage pattern and load-carrying capacity has been investigated using numerical simulations with non-linear material models and traction-separation interface behaviour. Further, it is also attempted to fundamentally engineer the epoxy polymers using nanosilica to improve their mechanical properties and environmental resistance. Finally, diffusion tests have been performed on the plain and nanoengineered epoxy polymers to understand the change in diffusion mechanisms due to nanoengineering, and a correlation has been established between the diffusion behaviour and the mechanical property degradation. The findings of this study will lead towards the development of stronger and more durable epoxy-bonded composite systems for marine applications.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"38 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, it is essential to establish an adequate recycling strategy to reduce composite waste. In this study, we prepared flax-fiber-reinforced thermoplastic composites and modified a liquid thermoplastic resin (Elium 188 O) with recycled thermoset composite fillers. The introduction of 15% silane-treated fillers into the polymer matrix resulted in a substantial increase in the energy release rate and fracture toughness at the fracture initiation stage in modes I and II. Specifically, compared with the unmodified matrix, the energy release rate and fracture toughness were enhanced by 44.8% and 42.8% (for mode I) and 40.5% and 85.4% (for mode II), respectively. Similarly, the flexural strength and modulus increased by 25.1% and 34.8%, respectively. Furthermore, the mechanical properties of thermoplastic composites will deteriorate significantly because of the low bonding strength between virgin and recycled materials. However, the flax-fiber-reinforced composites with a 15% silane-treated filler-modified polymer matrix maintained Young’s modulus and tensile strength of 89.9% and 91.2%, respectively, after 20 cycles of recycling. Overall, the strategy of inducing chemical-treated powdered composite wastes is a sufficient and low-labor-cost method to mitigate environmental pollution and improve the sustainability of recycled composite structures.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"304 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140614815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, performing a mechanical characterization and numerical simulation of the printed parts is imperative. This manuscript conducts experimental and numerical investigations on 3D-printed composites (onyx/glass fibers) that consider the infill pattern, walls, roofs, and floors of the samples. A numerical homogenization approach was adopted to identify the elastic mechanical parameters of the infill patterns. The results demonstrated the homogenization tool’s effectiveness in predicting the mechanical parameters of the infill patterns. Relationships correlating the infill density and each homogenized mechanical parameter were established, enabling the calculation of each mechanical parameter based on the used infill pattern and its density without reiterating the mechanical homogenization. Regarding the simulation of specimens under tension and flexure, the results indicated that the prediction error of the elastic modulus ranged between 2.87% and 11.84% for tension and between 4.42% and 8.45% for 3-point bending. The simulation of 3D-printed composites, considering all constituent elements of the specimens, allowed for examining stress fields in each element and identifying areas of highest and lowest stress. These findings can contribute to predicting the behavior of 3D-printed composites in the context of addressing engineering problems.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"32 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140617622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving the mechanical properties and durability of natural fiber composites is an important research approach. As one of the representatives of synthetic fibers, carbon fiber has excellent mechanical properties and chemical stability, but its high cost and low toughness limit further application. Combining environmentally friendly, low-cost natural fibers with carbon fibers can broaden the development of natural fiber-reinforced composites in industrial applications. In this paper, the composites made of jute fibers and polypropylene (PP) as well as carbon fibers coupled with KH550 modification were prepared and their properties were investigated. By introducing a macroscopic model similar to the core-shell structure, an environmentally friendly material with better mechanical properties was achieved, with carbon fiber woven fabric serving as the shell and jute fiber mat as the core. The results show that a low-cost hybrid composite was successfully prepared by using a small amount of carbon fiber woven fabric instead of jute fiber mat, and the tensile, flexural and impact properties of the composites were improved by 488.27%, 70.75% and 463.39%, respectively, compared with those of the pure jute fibers composites. This study provides a rapid and reliable approach to improve the mechanical properties of the natural fiber composites.","PeriodicalId":16943,"journal":{"name":"Journal of Reinforced Plastics and Composites","volume":"48 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140614850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
