摘要
采用云纹干涉法和数字散斑相关法对编孔和钻孔的三维编织复合材料制件进行孔边纵向应变场的测试 .结果证实 ,编孔复合材料制件更适合于作为含孔结构的复合材料连接件 .
The strain field in the zone around a pinhole was studied by the moire interferometry and the digital image correlation for two kinds of three dimensional (3 D) braided composite specimens (with a braided hole and a drilled hole respectively).This research demonstrates that the specimen with a braided hole is more suitable for the joint structure which contains holes.
