Abstract

Intersection ply, is a new composite fiber placement laminate mode, have potential to special mechanical properties relative to conventional composite ply. However, it is important to obtain the mechanical properties of this new laminate mode. In this paper, the mechanical properties of T800/ EP was studied, and the crossing intersection ply composite laminate samples were done with automated fiber placement.

The mechanical properties of T800/ EP crossing intersection laminate were tested and the microstructure of the sample was observed and analyzed. Results showed that the T800/ EP composite new laminate mode had high interlaminate shear properties compared with conventional laminate, and a downtrend was obvious in the aspects of the tensile property and compression performance.
