Polyester Composites Reinforced with Banana/plantain (Musa paradisiaca) Fiber Chemically Modified: Comparison with Fiberglass and Fique (Furcraea andina). Inf. tecnol.

Samples of composites were prepared using the hand lay-up technique with banana seudo-stem fibers (BSF), fique and glass, in a polyester matrix. The BSF was woven and analyzed untreated and chemically treated with acetic anhydride, epichlorohydrin, and their mixtures. The aim of this work was to characterize and compare the composites obtained using tensile tests, impact test, water absorption capacity and micrographs. The average value of tensile strength for the composite with treated BSF increased respect to untreated BSF and fique. Also, according to the water absorption tests, they showed the smallest weight increase. This finding was attributed to the higher hydrophobicity of the treated BSF. This in turn improved the adhesion with the matrix, as it was corroborated by the micrographs that showed lower displacement on the tensile fracture surfaces.
