Abstract Unidirectional arrayed chopped strands (UACS) are made by introducing regularly distributed slits into continuous fiber prepregs, which show better flowability and formability while maintaining high strength modulus. In this research, the quasi‐static compression three‐point bending tests were carried out on quasi‐isotropic laminates UACS laminates. The results illustrate that compressive modulus of 53.38 GPa 489.58 MPa, respectively, maintain relatively mechanical properties. decreased 7.3%, but its remained stable. Additionally, exhibit resistance to shear delamination damage retaining good To further explore behavior laminates, finite element models established numerically analyze properties mechanism under loads. present model could accurately simulate errors numerical analysis 6.03% 4.05%, respectively. From mechanism, ensure have lower energy release rates during damage, enables stable evolution plays a positive effect in reducing area inhibiting delamination. Highlights response loads was studied. laminate revealed. distribution difference between conventional CFRP is analyzed.
