Abstract
Functionality of natural fibre-reinforced composites continually attracts attention and offers a unique possibility. We fabricated several types of unidirectional and random bamboo fibre green composites, and examined their damping properties as a function of bamboo fibre content, fibre length, and fibre morphology. The loss factors of the bamboo fibre green composites decreased with increasing bamboo fibre content. However, the loss factors gradually decreased in the composites reinforced with fibre content higher than 40 mass%. The loss factors of random short fibre (10mm) reinforced green composites were higher than those of unidirectional ones. It can be seen that the damping factor of bamboo fibre green composites depended on fibre length and fibre content, and that vibration damping properties of the bamboo green composites were better than those of glass fibre reinforced plastics.
