Influence of contents of chemical compositions on the mechanical property of sisal fibers and sisal fibers reinforced PLA composites

摘要

The influence rule of the content ratio of cellulose, hemicellulose, and lignin on the tensile strength of sisal fibers (SFs) and the interfacial strength of SFs and poly lactic acid (PLA) matrix were investigated. Study showed that the microstructure and mechanic property of SFs were changed by alkali treatment. The proper contents ratio of cellulose, hemicellulose and lignin were good for both the tensile strength of SFs and the interface bonding of SFs and PLA matrix.
