Abstract
The four-point bending property was tested for 5224/CF3052 plain weave composite laminates. The damage resistance of laminates was analyzed with the different impact energy, including: dent depth ..damage width and damage area; The process, characteristic and mechanism of damage in laminates was discussed about impact and flexural test after impact; The influence of dent depth on the flexural property of laminates was researched. The results show that there is no relationship between impact energy and damage width, damage area;The flexural property of laminates is determined by the tension property of material;The laminar damage in the laminates is concentrated in the tensile layers; It is required to consider the decrease of flexural property caused by the impact when strength is designed; There is infection in the relation curve of the dent depth and flexural residual strength, flexural residual modulus-关键词
