Abstract:

The pre-impregnated woven fabric composite is a kind of uncured composite material. The preimpregnated woven fabric composite has its own properties which are not similar to those of the fabric or the fabric reinforced composite because of the existence of the uncured resin. A constitutive equation is based on the theory of continuum mechanics, considering the nonlinear viscoelasticity, and following the theory of algebraic invariants. At the same time, the process and method of picture frame experiment are formulated.
