Compósitos reforçados com fibras longas de bambu: modificação superficial e análise mecânica

Abstract

Composites are an important aspect for the development of products with specific properties. When composites are produced from renewable and biodegradable materials, they become sustainable due to their source of raw material. Natural vegetable fibers are abundant throughout the world and responsible for the mechanical properties of plants, which represent a potential target of study in the development of "green" materials. Based on this, the objective of this work is to produce composites of recycled thermoplastic polymer matrix with long bamboo natural fibers, from regional biomass, and analyse the influence of fibers as reinforcement in composites. The processes of washing, mercerizationand acetylation were conducted to chemically treat the fibers. The results, when compared with the available literature, indicated that the reinforced composite with long modified bamboo fibers presented better mechanical properties than thepolymermatrix. Consequently, it wasnoted that the techniques was used withsuccessful.
