Viscoelastic Properties of Chlorinated Polyethylene Rubbers Reinforced with Multi-crystal Iron Short Fiber
The viscoelastic properties of Multi-crystal Iron short fiber-reinforced chlorinated polyethylene (CPE) matrix composites have been studied by using a dynamic mechanical thermal analyzer (DMA). Due to the presence of agglomerates, storage modulus increase strongly with increasing the filler content and this increase is more important at the rubber zone (T>Tg) than at the glassy region (T<Tg). As the short fiber content is increased, the maximum loss modulus peak values also increase, indicating that the dissipation of energy as heat has been improved by the adding effect of short fiber. The value of loss factor reaches the maximum at 9wt％ short fiber content, and finally decreases again. The value of TA for composite reaches the maximum when the composite contains 12wt％ short fibers. This may imply that the added short fiber improves the damping properties of the composite and a new damping material with higher loss factor value and efficient stiffness in the region of practical temperature can be obtained by changing the short fiber content.
