摘要：
In this work, the dynamic mechanical behavior of jute fiber-reinforced epoxy foams was investigated. The influence of various fiber and microvoid content on shear modulus, frequency and log decrement was discussed. Experimental results showed that the 42 vol.% fiber content significantly enhances the shear modulus. The shear modulus and frequency were decreased with increasing microvoid content in the epoxy matrix. The jute fiber as reinforcement affects the temperature of the log decrement peak. Increasing fiber and microvoid content induced a decrease and an increase of the log decrement peak values, respectively.
