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.

Summary: This study investigated the mechanical properties of basalt/ramie/polyester hybrid composite laminates. A matrix of 45% polyester was used for good bonding properties. The laminates were fabricated using a hand layup technique, with different stacking sequences and impregnated in the polyester matrix. Mechanical characterization tests were conducted and results showed that sample number seven with stacking sequence BRBRBRB had the highest strength and hardness. Natural fiber-reinforced composites are increasingly used in the automotive industry, particularly in electric vehicles.

Summary: Due to its exceptional properties, such as high-temperature resistance and mechanical characteristics, as well as relatively lower price, the demand for carbon fiber has been increasing. However, this increasing demand has also created a waste recycling problem. To address this issue, this research aims to produce a recycled composite made from different carbon fiber leftover resources to reinforce the growing demand for materials. The recycled composites are tested and analyzed to study their thermal properties.

Summary: This research investigates the impacts of surface treatment and the number of ramie fiber layers on the vibrational and mechanical characteristics of a glass/ramie fiber reinforced hybrid polymer composite. The study found that hybridization and NaOH pre-treatment to a certain ratio can increase the mechanical strength of the hybrid composite compared to natural fiber composites.

Summary: Nowadays, industries are focused on low-cost, biodegradable materials with long lifespans. This study investigates the effect of fiber orientation on the mechanical and morphological evaluation of composite materials made from acacia and raffia fibers combined with epoxy resin. Different types of composites were fabricated and tested according to ASTM standards, demonstrating varying mechanical behaviors. Scanning electron microscopy was used to examine the internal structural failure of the composites, revealing the presence of fiber cracks, pullouts, and voids.

Summary: Natural fibers are increasingly used as sustainable reinforcement for composites due to their carbon capture and renewability. However, predicting the tensile properties of woven fabric reinforced composites is challenging due to their complex structure. This study analyzed macro and micro ramie fiber reinforced composites to provide predictions for woven fabric reinforced composites. The improved ROM model significantly enhanced the prediction accuracy and efficiency of ramie plain woven fabric reinforced composites.

Summary: This study experimentally investigated the influence of fiber architecture on the mechanical properties of E-glass fiber reinforced polymer composite and predicted the effect of fiber volume fraction on strength using second order polynomial regression models. The experimental results of tensile and flexural properties of composites were in good agreement with the regression model predictions, indicating the models' statistical significance and goodness of fit.

Summary: Replacing artificial fibers with natural fibers to fabricate fiber-reinforced resin matrix composites is a research hotspot at present. How to improve the poor compatibility between plant fiber and resin matrix is hot spots in this area. Our work aims to modify RFF reinforced epoxy resin (RFF/EP) composite laminates with silicon polymer (PSOL) and improve the performance of the composite laminates.

Summary: Due to their availability, environment friendliness, low cost, and biodegradability, natural fiber composites made from lignocellulosic fibers are gaining popularity. In this study, Cissus vitiginea L. polymer composites (CVPC) were fabricated with different amounts of Cissus vitiginea L fiber. Mechanical characterization showed that alkali treatment enhanced the bonding between the fibers and the epoxy matrix, resulting in improved strength properties. Scanning electron microscope analysis confirmed the filling of cracks and pores by the treated fibers, further improving the mechanical properties. This research demonstrates the potential of using treated Cissus vitiginea L stem fiber for thermoset plastic green composites.

Summary: The present study investigated the effects of silane treated ramie fiber and organically-modified montmorillonite nano clay on the performance of epoxy resin composites. The results showed that the treated ramie fiber exhibited high resistance to impact and shear loading, and the addition of OMMT nanoclay improved the load bearing and adhesion properties. The composites demonstrated high interlaminar shear strength and dimensional stability in drilling, making them suitable for various engineering applications.

Summary: This study investigates the water absorption behavior of Indian ramie/epoxy composites and its impact on mechanical and tribological properties. The results show a decrease in tensile strength, flexural strength, impact strength, and hardness after water immersion, along with reduced friction coefficient and wear performance. Scanning electron microscopy analysis revealed weakening of the fiber-matrix interface as the main cause of property degradation.
