Summary: This study found that alkali-treated rice straw can significantly improve the bending strength of geopolymer composites and provide better enhancement effects. As the fiber content increases, the water absorption thickness swelling rate and water absorption of the composite materials also increase.

Summary: This study investigates the hybridizing effect of alkali-treated groundnut shell powder (T-GSP) on basalt fiber (BF) reinforced linear low-density polyethylene (LLDPE) composites at different weight fractions. The results show that adding 15 wt% T-GSP with 20 wt% fresh basalt fibers significantly improves the mechanical, thermal, and thermomechanical properties of the hybrid composites.

Summary: This study analyzed the influence of calcium carbonate filler loadings on the properties of pine fiber reinforced polyester composites. The results showed that the fillers improved the physical, mechanical, thermal, and morphological properties of the composites. The fillers enhanced the strength, hardness, and thermal resistance of the composites through filling air gaps and enhancing interfacial bonding.

Summary: In this study, unsaturated polyester (UP) filled with date palm fibers (DPFs) was produced using short untreated and alkali-treated date palm fibers of 5-10 mm. The composite reinforced with 10% TDPF achieved the highest tensile and flexural strengths, while the composite produced with 30% TDPF achieved the maximum tensile, flexural moduli, and Izod impact strength. Scanning electron microscopy (SEM) micrographs demonstrated improved adhesion between UP and TDPF. This research highlights the potential of using date palm fibers as a renewable natural resource for eco-friendly composites with enhanced performance.

Summary: This study investigated the influence of fly ash filler on the physico-mechanical properties and abrasive wear of alkali-treated Himalayan agave fiber/polyester composites. The optimal combination of fiber loading, normal load, fly-ash content, and speed was determined using Taguchi's method. SEM analysis revealed the dominant wear mechanism on the worn surfaces of the composites.

Summary: In this study, the researchers improved the mechanical and thermal characteristics of polymer composites by using pumice powder treatment on corn husk waste fibers. The results showed that the SBA/CHF composites had enhanced interfacial adhesion, leading to improved mechanical and thermal properties. The composite with a volume fraction of 5:30 exhibited the highest values among all composites, indicating the strong SBA/CHF interface bonds. The morphological study further revealed the influence of CHF and SBA on the composite properties.

Summary: Due to environmental issues and high cost, natural or cellulosic fibers have become a promising reinforcement for polymer composites. Hybridization of natural and synthetic fibers can improve the mechanical properties. This research evaluates the influence of glass fiber hybridization on the mechanical properties of alkali-treated kenaf-epoxy composites and concludes that the hybrid composites show improved tensile and flexural strength and modulus.

Summary: This study focuses on the preparation of high ductile alkali-activated fiber reinforced composite and experimental investigation of their mechanical properties at different curing ages. The results show an initial increase and subsequent stabilization of compressive and tensile strength with increasing ages, while the tensile strain capacities remain at a higher level. Additionally, parameters at the meso-scale can be well correlated with the tensile properties of the materials at different ages.

Summary: Ramie fiber-reinforced polymer (RFRP) composites were studied under hydrothermal conditions to understand the influence of different resin matrices on their mechanical properties and durability. The study found that RFRP composites reinforced with phenolic resin (RFRPR) had better flexural and short-beam strength, while composites reinforced with unsaturated polyester (RFRUP) had higher water absorption and diffusion coefficients. The erosion of water molecules led to deterioration in the interfacial bonding performance of the RFRPR composite. This study lays the foundation for further promotion and application of RFRP composites.

Summary: This research investigates the degradation mechanisms and mechanical properties of alkali-modified bamboo fiber composites under long-term water aging. The study found that alkali-treatment reduces the moisture content of composites and the reduction is greater with longer treatment duration. The tensile strength and modulus of composites reach their maximum values under dry conditions, and then gradually decrease. Beyond 120 aging-days, the tensile strength and modulus of modified fiber composites significantly decrease. On the other hand, the raw and 0.5-h-modified fiber composites show good aging resistance.
