Mechanical Properties Prediction of Interlayer Enhanced Laminated Carbon Fiber Composite Materials Containing Inclusions

Article Preview

Abstract:

Micro structure of laminated carbon fiber composite (L-CFRP) is complex and random distributed. So that the current prediction of mechanical properties for interlayer enhanced L-CFRP is not so accurate. To solve this problem, the inclusion fibers are dealt with equivalent processing using Mori-Tanaka theory and Esshelby equivalent inclusion principle. And then the equivalent cell model of interlayer enhanced L-CFRP could be obtained. The finite element method is adopted to predict the elastic mechanical properties of interlayer enhanced L-CFRP. Through the simulation and tests, the error of this prediction method is 3.72%. So the proposed prediction method is proved to be effective.
