The Static Mechanical Properties of Carbon/Epoxy Composite Laminates with Voids

The effects of voids on the tensile and compressive properties of CFRP laminates were discussed in this paper. The tensile and compressive strength of specimens decreased with the porosity increasing from 0.33% to 1.50%. The empirical models of the tensile strength and the compressive strength of CFRP laminates with different porosities are established by using ORIGIN software. The evolution laws of the tensile strength and the compressive strength with different porosities were corresponding to the form of exponential function.
