Abstract
In this research it was produced composites reinforced with bamboo fiber, with lengths ranging from 5 to 15 mm. Bamboo fibers extracted from basal, intermediate and top of the bamboo plant, and then the fibers were subjected to the equipment granulator mill, where we obtained the desired lengths. Were made 8 (eight) specimens defined by the following ratio of mass fraction; 5.41%; manufacturing was performed by hand molding using unsaturated polyester resin with the ratio of curing agent/resin 0.33%. The results of the tensile strength of the composite bamboo basal region was 14.20MPa, the result of the composite bamboo intermediate region was 16.03MPa and the result of bamboo composite top area was 16.93MPa. The tensile results showed that the top region of the bamboo plant showed better mechanical strength. Fractures of the composites were observed by scanning electron microscopy (SEM).
