The dynamic mechanical properties of shape memory epoxy polymer (SMEP) and 4-harness satin carbon fiber weave reinforced composites were tested by DMA 8000, the glass-transition temperature Tg, the storage modulus E, the tangent of loss angle tan δwere calculated. The experimental results indicate that SMEP and 4-harness satin carbon fiber weave reinforced composites have significant phase transition mechanical behavior, in which E differs beyond one-order around Tg. This prove that the SMEP and 4-harness satin carbon fiber weave reinforced composites have good shape memory capacity. The thermoset SMEP involved with three kinds of carbon fiber weave reinforced composites will lead to Tgand tan δreduction, but E is significantly enlarged. Tgand tan δof the same SMEP carbon fiber weave reinforced composites are almost in common, but E differs greatly in its warp direction and weft direction.
