This polymer being hydrophobic and apolar, it will be unlikely to generate strong interactions with clay leaves called organophilic maghnite. The challenge of this study will therefore be to manage the load/polymer interfaces by using montmorillonite with specific surface treatments by adding a surfactant Cetyltrimethylammonium bromide. Therefore, a significant improvement in mechanical and thermal properties was observed. The properties of PVDFNC nanocomposites were evaluated using various physico-chemical techniques (XRD, FTIR, TGA, DSC, TEM, SEM). The results of the structural and thermal measurements carried out on these products reveal that the structural concept of the surfactant influences both the morphological profile, the thermal and mechanical properties of the nanocomposites obtained. Accelerated crystallization is observed in PVDNC nanocomposites as an effective nucleation agent, the crystals formed are predominantly β shaped and have a small number of polar α crystals. Measurements by X-ray diffraction, as well as transmission and scanning electron microscopy indicated that modified maghnite was perfectly distributed 3 % by weight in the polyvinylidene fluoride matrix. The mechanical properties of the nanocomposites were evaluated according to the filler material used and the polyvinylidene fluoride matrix.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48434928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The STFP composites are fabricated using compression moulding methods with varying fibre weight percentages (5 %–50 %) and fibre lengths (5 mm–50 mm). It has been observed that the impact, flexural, and tensile strength of STFPs improve as the length of the fibre increases, up to a maximum of 40 mm. After that, these properties start to decrease as the length of the fibre further increases. Further, the analysis revealed that STFPs exhibited an increase in properties when the fibre weight percentage was less than 40 %, followed by a decrease in properties as the fibre percentage increased beyond that point. The impact strength of STFP is around 8.2 J/cm2. Similarly, the STFP has a flexural modulus and strength of about 3.4 GPa and 82.6 MPa, respectively. Lastly, the tensile strength of STFP is around 78.26 MPa, the elongation at break is between 6.25 % and 9.36 %, and the Young’s modulus is 11.8 GPa. The matrix and fibre interaction were examined by Scanning Electron Microscopy (SEM). Furthermore, Thermogravimetric (TGA) and Differential Scanning Calorimeter (DSC) analyses are carried out. From these analyses, the thermal stability of STFP is 200 °C and its activation energy is 65.48 kJ/mol. After a thorough comparison with other well-known natural fibres, the proposed properties of STFP demonstrate its superiority as a practical and effective natural fibre composite.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":"0 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41338098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need for environmentally and biodegradable fibers has created a demand in the transportation industry. In this study, bio castor seed shell (C), glass fiber (G), and SiC (SC) fillers in a constant weight fraction (10 %) were reinforced separately with varying weight fractions (5–25 %) of African teff and snake grass fibers to improve the mechanical properties of the hybrid composites. Both African teff and snake grass fibers were subjected to alkaline treatment to remove amorphous elements such as hemicellulose, lignin, and wax, resulting in high surface roughness. The hybrid composites were fabricated by the compression molding technique and their mechanical properties were characterized as per ASTM standards. The fractured surface of the treated fiber was examined by scanning electron microscopy. From the results, it was found that SC10SG20AT showed maximum mechanical properties compared to C10SG20AT and G10SG20AT due to higher load-bearing capacity of SiC filler. Therefore, SC10SG20AT can be recommended for lightweight applications.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42172837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research focuses on reducing stress concentration. Circular holes made on the composite structural member induce stress-concentrated regions. These stress-concentrated regions around the circular hole (considered as a weak section) were strengthened by adding synthetic fibre (local hybridization) in the form of fibre stitches (locked loop stitch). Through conducting a single fibre pull-out test, the present study analysed the impact of incorporating synthetic fibres in stitch form and the enhancement of Interfacial Shear Strength (IFSS). The load acting on the broken warp fibres is distributed to the broken weft fibres when the number of concentric stitches increases. The increment of concentric stitches resulted in the increase of IFSS due to localized hybridization. The tensile test results also show a significant improvement with 110 Nmm axial fastening force, from 6.749 MPa (for the natural fibre composite) to 76.91 MPa (for locally hybridized with eight concentric stitches). A simple bolted lap joint with local hybridization around the hole has been evaluated for different clamp-up forces. The best combinations of the clamp-up force and the extent of hybridization have been identified. SEM images illustrate the reduced voids and the reduced fibre pull-out due to the local hybridization around delamination-prone areas.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42744069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
