Paragraph starter

Research by Rachtanapun et al. (2024) demonstrates that plasma treatment of bamboo fibers significantly enhances the mechanical properties and water resistance of epoxy composites. This improvement is attributed to better interfacial adhesion resulting from altered fiber surface chemistry, leading to a notable increase in flexural strength and modulus, and a reduction in water absorption. This highlights the critical role of surface modification in optimizing composite material performance for design applications.
