摘要

Biocomposites were produced using polycaprolactone and starch as matrix, and sisal fibers as reinforcement. The matrix is a biodegradable commercial product called MaterBi-Z, which is based on a polycaprolactone and starch system. The re- lationship between processing conditions and properties is reported. An alkaline treatment was performed in order to improve the adhesion and the compatibility of the fiber with the matrix. The effect of the treatment on the tensile properties and morphology was determined. Fiber content enhances the tensile properties of the biodegradable composite. The experimentally observed tensile properties (modulus and tensile strength) of short sisal fiber reinforced MaterBi-Z ~atrix composites with different fiber loading are compared with the existing theories of reinforce- ment. SEM photomicrographs of the fractured composite surfaces are also analyzed.
