Stiffness Matrices of Woven Fabric Composites with Resin Cure

Abstract:

Article Preview

Analytical models are presented for investigation of cure dependent stiffness of woven fiber composites. A linear-like correlation is adopted between the material properties and resin degree of cure. Fiber undulation model takes into account the fiber continuity and undulation and has been adopted for plain weave fiber mats geometry modeling. The analysis is performed on a unit cell, which is a representative of the entire fiber mat lamina. The classical laminate theory (CLT) is applied to determine stiffness constants in the infinitesimal region of the composites unit cell. The theoretical models can prediction the changes of stiffness matrices with the degree of cure. A case studies show that the elements of the stiffness matrices showed exponential increase with the resin degree of cure.
