Summary: An optimized new fiber architecture was developed to improve the mechanical performance of natural fiber-based thermoplastic composites. Short jute fiber-based composites showed significant improvement in mechanical properties compared to other natural fiber architectures. The use of chemical treatments on jute fibers and the application of a low-cost production process contributed to the enhancement of the composites' mechanical properties.

Summary: Silk fibers have great potential for high impact resistance in composites due to their stiffness, strength, and high strain to failure. Using thermoplastic matrix materials with high strain to failure can enhance the impact resistance above that of the pure matrices. The adhesion between fiber and matrix and the fiber architecture also play significant roles in impact resistance.

Summary: This work investigates the elastic properties of natural fiber composites (NFC) reinforced with Luffa and Palm in high density polyethylene (HDPE) and polypropylene (PP) matrixes, considering the variation of fiber volume fractions (V-f). Representative volume element (RVE) models with unidirectional and chopped random fiber orientations were used to predict the modulus and Poisson's ratio. Analytical approaches such as rule of mixture (ROM), Halpin-Tsai, Chamis, and Nielsen were employed to compare and validate the results obtained from finite element analysis (FEA). The results show that RVE Chopped has the highest accuracy in predicting the elastic properties of luffa and palm-reinforced thermoplastics, while RVE unidirectional model agrees well with the analytical results.

Summary: Pultruded thermoplastic composite profiles offer advantages over conventional thermoset counterparts, such as high impact toughness, recyclability, and smaller environmental footprint. By using preconsolidated tapes made from glass fiber/polypropylene commingled yarns with high fiber content, thermoplastic profiles with excellent mechanical properties can be produced.

Summary: The objective of this study was to compare different chemical recycling methods for thermoplastic acrylate-based composites in terms of material recovery. The goal was to recover undamaged basalt fabrics for reuse as reinforcements in second-generation composites. Two protocols, ultrasound and mechanical stirring, were compared. It was found that the dissolution protocol using mechanical stirring was more effective in recovering undamaged fabrics with no residual resin. The mechanical properties of the second-generation composites were equivalent to those of the first-generation composites.

Summary: This paper investigates the effect of carboxylic-acid-modified polypropylene (PP) on the mechanical properties of carbon fiber (CF)/polypropylene (PP) composites, and proposes a new interface design to improve the mechanical properties. The addition of carboxylic-acid-modified PP and poly-2-vinyl-2-oxazoline (Pvozo) coating on CF resulted in better interfacial adhesion and improved tensile properties. Increased entanglement with matrix PP molecules and different bonding modes at the CF/PP interface were suggested to contribute to the mechanical properties of the composite.

Summary: This research focuses on lightweight products for the transportation industry, introducing recycled carbon fibers and elastomers to polypropylene matrix to improve strength and toughness. The addition of 20 wt% recycled carbon fibers led to significant enhancements in heat distortion temperature, tensile strength, and stiffness. Fractography analysis revealed that the presence of fibers predominantly governs the impact resistance characteristics of the composites.
