Summary: The research found that the roselle fabric composite has superior mechanical properties, while the sisal fabric composite has lower tensile and impact strengths. However, the sisal fabric and roselle fabric composites have similar flexural properties. The sisal fabric composite has the highest loss factor peak, with the peak height increasing with higher sisal fiber content in the roselle/sisal fabric composites.

Summary: The study found that introducing asphaltene fillers into epoxy resin affects the material properties, such as increasing viscosity, enhancing Young's modulus, and storage modulus. With an increase in asphaltene content, aggregation and network structures appear in the microstructure, while there is minimal impact on glass transition temperature, damping properties, and thermal stability.

Summary: This study aims to investigate lightweight thermoset fiber-reinforced composites with extremely high biobased content. The most promising formulations were used to produce flax fiber reinforced composites, and the properties of the new biocomposites were assessed. The results are very encouraging, as the stiffness-to-weight ratio is comparable to typical epoxy-glass composites.

Summary: The research investigated the effect of fiber surface treatment on sisal fibers and their epoxy composites, showing improvements in surface roughness, crystallinity, and thermal stability of chemically treated fibers. The wear resistance of chemically modified SFREC was increased compared to untreated SFREC, with the best wear properties demonstrated by alkali-treated SFREC. Applied load and sliding distance were observed to have the most defining effect on wear volume loss of SFREC according to ANOVA findings.

Summary: The purpose of this work is to evaluate the effectiveness of low-cost and environmentally friendly chemical modification on jute fibre-reinforced epoxy composites (JFREC) using sodium hydroxide (AT), sodium carbonate (ST), and sodium hydrogen carbonate (SHT) in terms of morphology, water absorption, mechanical, and tribological characteristics. Results showed significant improvement in mechanical properties such as tensile strength, tensile modulus, and impact strength for AT JFREC (38.08%, 30.56%, 31.66%), ST JFREC (70.03%, 33.06%, 41.30%), and SHT JFREC (24.69%, 8.88%, 22.61%) compared to untreated JFREC. The study also confirmed that the chemical modification improved fibre-matrix adhesion, leading to enhanced water absorption resistance and tribological properties of the modified JFREC. The improved mechanical and tribological properties make the chemically modified JFREC potentially applicable in automotive and packaging industries.
