The influence of fiber type and conformation on the damping property of FRP composite

Abstract

In order to get a fiber reinforced plastic(FRP) composite with good damping property as well as good mechanical properties, different types of reinforcing materials were used to reinforcing a damping resin. The influence of fiber types and conformation on the damping property of the composite are tested. Compared to the glass fiber(GF), carbon fiber(CF) can improve the damping factor of the composites; the highest tanδ value is 0.827 while the T _g is 22.5 °C. The style of the fibers also influences the damping factors of the composite. The composite reinforced with mat has higher loss factors than that composite reinforced with clothe for the reason that the former has the ability to deform and the composite has higher resin content. The loss factor of GF mat reinforced composite is 0.704 while the T _g is 27 °C. Both composite has good damping properties and can be used as the damping layer of the structural damping composite.
