A CONSTITUTIVE MODEL FOR PRE-IMPREGNATED WOVEN FABRIC MATERIALS

摘要：

The pre-impregnated woven fabric composite (PWFC) is a sort of composites which is widely used in space inflatable structures with uncured state of material.The PWFC has its own properties dissimilar to the fabric or the fabric reinforced composite because of the existence of uncured resin.In the present paper,a constitutive equation has been formulated exhibiting nonlinearly viscoelasticity of PWFC.A picture flame experiment has been performed to testify the verification of the constitutive equation.The results have shown that the equation can explain the properties of the material well.
