Abstract
The main objective of this research is to evaluate the mechanical and electrical resistivity of bamboo fiber reinforced polypropylene composite. Bamboo fiber reinforced polypropylene composite was fabricated by compression molding process and the bamboo fiber was extracted from the bamboo culm using mechanical extraction process. The bamboo fiber was characterized using XRD, optical micrograph and SEM. For the evaluation of mechanical properties hardness was measured and found to have 94 shore. XRD method was used for calculating the crystallinity of bamboo fiber and found 69% of crystallinity. At constant temperature (about 30°C), frequency dependence of electrical resistivity was also observed over a wide range. Electrical resistivity of the composite was found to decrease approximately by 90.38% when frequency was varied ranging from 1 KHz to 1000 KHz.
