Z-pin technology is a notable method for laminated composites to improve the resistance to delamination. However, the presence of the Z-pins unavoidably leads to a degradation of the in-plane strength of the composite. This paper mainly explores the influence of the Z-pin insertion pattern on the in-plane compression performance of laminates by testing the compression properties of laminates with Z-pins inserted in different patterns. Meanwhile, the influencing mechanism is researched by means of finite element analysis. The results show that the through-thickness reinforcing pins decreases the compressive strength by vitiating several bunches of load-bearing fiber. The compression strength of Z-pinned laminates is inversely proportional to the fraction of the Z-pins inserted in the cross-section vertical to the compression loading direction. If permitted by the demands of inter-layer reinforcement, Z-pins should be distributed along the compressive loading direction.
