“…The reinforcement of chemically treated sisal/hemp fillers which are usually elastic in behavior, improves the hardness of the specimen gradually when compared with untreated samples, as observed in Table 3. The lower hardness of SUBE56, HUBE56, and SHUBE56 composites may be advantageous in incrementing the resistance from erosion of specimens 143 . The shore hardness of the KSCBE56, KHCBE56, and KSHCBE56 composites was enhanced because of the homogeneous distribution of the sisal‐hemp fillers in the bio epoxy matrix by reinforcing suitable fillers and solid interfacial bonding within the Kevlar fabric, sisal‐hemp fillers, and polymer matrix.…”

In the present investigation, the chemically treated and untreated sisal/hemp fibers, fly ash or titanium carbide (TiC) nanofillers, and Kevlar fabrics reinforced bio epoxy (Sr 56) polymer matrix were manufactured using the wet layup method. Experimentation was performed to study the physical, mechanical and thermal properties. This investigation also includes determining the influence of accelerated weathering on the specimen surface for 5 months. The tensile fracture of the sample before and after the accelerated weathering from scanning electron microscope (SEM) pictures exhibited that the extensive failure principles in the laminates in terms of matrix cracking, fiber breakage, delamination, and fiber pull out. The thermal analysis examined the onset, endset temperature, transition loss, and carbon residue which were also reduced after the accelerated weathering. It exhibits that adding fly ash or TiC nanoparticles as an altered inhibitor against the weathering in the bio epoxy hybrid composite scheme can reduce the undesirable impacts from moisture and Ultra‐violet light exposure.Highlights Sisal/hemp fibers were chemically treated to reduce hydrophilicity. Contact angle of KSCHCTBE56 improved to 84.04°. SEM confirmed uniform dispersion of fillers and enhance mechanical strength. Mechanical and thermal characteristics reduced after accelerated weathering.

“…These trends are attributed to the ability of crump rubber particles to effectively absorb the heat during sliding wear. Thermogravimetric analysis curves reported in [42] reveal that all crump rubber-epoxy composites reveal a one-step degradation mechanism, and onset of degradation for EC-10, EC-20, and EC-30 takes place at 359, 362, and 365 °C, respectively. Furthermore, we also found that EC-30 registers a higher final degradation…”

The effect of crump rubber on the dry sliding wear behavior of epoxy composites is investigated in the present study. Wear tests are carried out for three levels of crump rubber (10, 20, and 30 vol.%), normal applied load (30, 40, and 50 N), and sliding distance (1, 3, and 5 km). The wear behavior of crump rubber–epoxy composites is investigated against EN31 steel discs. The hybrid mathematical approach of Taguchi-coupled Grey Relational Analysis (GRA)—Principal Component Analysis (PCA) is used to examine the influence of crump rubber on the tribological response of composites. Mathematical and experimental results reveal that increasing crump rubber content reduces the wear rate of composites. Composites also show a significant decrease in specific wear values at higher applied loads. Furthermore, the coefficient of friction also shows a decreasing trend with an increase in crump rubber content, indicating the effectiveness of reinforcing crump rubber in a widely used epoxy matrix. Analysis of Variance (ANOVA) results also reveal that the crump rubber content in the composite is a significant parameter to influence the wear characteristic. The post-test temperature of discs increases with an increase in the applied load, while decreasing with an increase in filler loading. Worn surfaces are analyzed using scanning electron microscopy to understand structure–property correlations. Finally, existing studies available in the literature are compared with the wear data of the present study in the form of a property map.

“…Numerous studies have indicated that elastomers are capable of absorbing the impact energy of erosive particles, and exhibit excellent erosion resistance under certain conditions. [34][35][36] In this study, a thermal deicing nanocomposite lm with solid particle erosion performance was fabricated using a highly elastic material, thermoplastic polyurethane (TPU), as the matrix, through a simple "spray-hot pressing" method. The composite lm has a sandwich structure that can uniformly distribute the ller and reinforce the structure.…”
