Summary: The hygrothermal aging behavior, finite element analysis, and mechanical properties of RF/PETG composites modified with a silane coupling agent and CNTs were investigated. The water uptakes of the composites with different modifications after 90-days aging were low. Surface modifications of the ramie fibers did not significantly influence the water uptakes, but were related to the hydrophilicity difference of the composites. The bending strengths of the modified composites increased compared to the untreated composites, and the bending properties changed after aging.

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: In this study, ammonium polyphosphate (APP) was coated on the surface of ramie fabrics (RFs) to obtain flame-retardant RF reinforced epoxy resin composites. The flameretardant composites achieved a limiting oxygen index of 33.8% and UL-94 V-0 rating when the weight gain rate of APP in RFs was about 20%. Additionally, the flame-retardant composites showed reduced peak heat release rate, total heat release values, and smoke production. However, the presence of APP had a negative effect on the internal compatibility and mechanical properties of the composites.

Summary: The study focuses on the water absorption and mechanical properties of ramie-fiber-reinforced polymer composites (RFRP) in a hydrothermal environment. The moisture absorption rate of RFRP is mainly influenced by ambient humidity. Before reaching moisture absorption equilibrium, the mechanical properties decline rapidly and then stabilize, with a significant decrease in mechanical properties as humidity increases. The interfacial bonding performance of RFRP is reduced by water molecules, with a greater degradation of modulus than strength.
