摘要: 对复合材料胶接用金属材料及表面处理方式进行简述,并对TC4钛合金、5052铝合金、304不锈钢、4J36殷钢的喷砂工艺参数进行实验研究。以喷砂时间为变量,以金属材料喷砂后与复合材料试件的胶接拉剪强度表征金属材料喷砂后的表面状态。实验表明:在喷砂材料为40目石英砂,喷砂距离约为150 mm,喷砂角度为45°,喷砂压力为0.5 MPa的条件下,TC4钛合金的合理喷砂参数为30 s±5 s/15 cm2,5052铝合金的合理喷砂参数为20 s±5 s/15 cm2,304不锈钢的合理喷砂参数为45 s±5 s/15 cm2,4J36殷钢的合理喷砂参数为25 s±5 s/15 cm2

Abstract: The paper introduces metal materials and their surface treatment for bonding of composites, and tests the sandblast parameters of TC4 titanium alloy, 5052 aluminum alloy, 304 stainless stell and 4J36 invar stell. Taking sandblast time as variable as well as tensile shear strength between metal and composite after bonding to verify the surface condition under metal sandblasting. The test demonstrates that appropriate sandblasting parameter of TC4 titanium alloy is 30 s±5 s/15 cm2 and 20 s±5 s/15 cm2 for 052 aluminum alloy, 45 s±5 s/15 cm2 for 304 stainless stell, 25 s±5 s/15 cm2 for 4J36 invar stell under the condition of 40 mesh quartz sand, the sandblasting distance of 150 mm, the sandblasting angle of 45°, the sandblasting pressure of 0.5 MPa.
