Abstract
In-plane compressive strength of z-pinned unidirectional composites is predicted by using variational principle and maximum shear strength criterion. The fiber waviness and the fiber volume content concentration, which are inhomogeneously distributed, as well as the resin-rich pocket, are taken into account. The predicted results are in good agreement with the test data. The effects of pin parameters on the compressive strength of z-pinned laminates are discussed in detail. The results showed that in-plane compressive strength of laminates decreases as the diameter of pin increases under the same pin volume content. Compressive strength decreases as the pin volume content increases under the same pin diameter. The non-linear shear property of matrix has relatively remarkable influence on compressive strength of unidirectional z-pinned laminates when pin diameter is small.
