残余应力严重影响碳纤维增强树脂基复合材料（carbon fiber reinforced polymer, CFRP）的力学性能，甚至诱发材料开裂，因此，准确测量CFRP层合板的层间非均匀残余应力对于其制备工艺改进具有重要意义。通过逐层钻孔法测量CFRP层合板层间非均匀残余应力，采用有限元仿真计算每层释放残余应力与应变之间的标准系数矩阵；利用系数矩阵和实测应变计算CFRP各层残余应力。结果表明：CFRP层合板整体延厚度方向呈现外压内拉的应力分布；残余应力测量方差随钻孔深度增大而增加，板内越靠近中间的铺层，其层间残余应力值越大，非均匀性越高。

The mechanical properties of carbon fiber reinforced polymer (CFRP) composites are significantly impacted by residual stresses, which can even induce material cracking. Consequently, the accurate measurement of interlayer non-uniform residual stresses in CFRP laminates is of paramount importance for improving their manufacturing processes. The incremental hole-drilling method was employed to measure the interlayer non-uniform residual stresses in CFRP laminates. Finite element simulation was used to calculate the standard coefficient matrix between the released residual stresses and strains released in each layer. Coefficient matrix in conjunction with the measured strains was utilized to compute the residual stresses within each layer of the CFRP. The results indicate that the CFRP laminates exhibit an overall stress distribution characterized by compressive stresses externally and tensile stresses internally along the thickness direction. Furthermore, the measurement variance of residual stresses increases with the increase in drilling depth, and the interlayer residual stress values and their non-uniformity are higher in the layers closer to the center of the plate.
