- As new structural composites, X-cor sandwich effectively improves the mechanical properties of the foam sandwich in thickness direction due to its high specific strength and specific stiffness. In this article, by introducing the correction coefficient, the modified calculation model of X-cor sandwich's compression modulus was established based on homogenization theory. The correction coefficient of compression modulus is 0.3. The effects of X-cor sandwich's structural parameters on the compression modulus were investigated. In Z-pin's inserting angle range of 0°-30°, the compression modulus decreases with the increase of inserting angle and increases with the increase of Z-pin's density and diameter. The error range between the analysis of modified model and the test is -13.9%-10.6%. The analysis is in good agreement with the test, which indicates that the modified calculation model can be used to calculate the X-cor sandwich's compression modulus.
