Abstract

Adhesives and industrial adhesive tapes are increasingly replacing conventional methods of permanent bonding of materials across various industries, including the automotive, aerospace, and energy sectors. The continuous development of bonding technologies positions adhesive bonding alongside welding, soldering, and brazing as one of the primary methods for joining composite and metallic materials, ensuring reliable connections. This article presents the results of shear strength testing of adhesive joints, metallographic observations, and flame resistance tests based on UL94 for adhesive joints. The investigations were conducted on joints fabricated from aluminum alloy EN AW-5754 (PA11; AlMg3), flame-retardant composite EPGC 202, and the combination of aluminum alloy with composite material. Silane-modified polymer adhesives (MS polymer), a polyurethane adhesive, and industrial mounting tape, all classified as HL3 in terms of fire resistance, were selected for the bonding processes. The best results were observed with silane-modified polymer adhesives, achieving shear strengths > 1000 N for laminate-laminate and laminate-aluminum joints. The shear strength results for the acrylic tape exceed those of one MS polymer adhesive and the polyurethane adhesive, indicating its potential application in scenarios requiring high-quality bonds while meeting the highest fire hazard classification, HL3, as specified by the EN 45545-2 standard.

用阻燃工业胶粘剂粘合接头的电阻

粘合剂和工业胶带正在越来越多地取代传统的材料永久粘接方法，包括汽车、航空航天和能源部门。粘接技术的不断发展使粘接与焊接、焊接和钎焊一起成为复合材料和金属材料连接的主要方法之一，确保了可靠的连接。本文介绍了粘接接头的抗剪强度试验、金相观察和基于UL94的粘接接头的阻燃试验结果。对铝合金EN AW-5754 （PA11; AlMg3）、阻燃复合材料EPGC - 202以及铝合金与复合材料的复合材料制备的接头进行了研究。采用硅烷改性聚合物胶粘剂（MS聚合物）、聚氨酯胶粘剂和工业安装胶带进行粘接，其耐火等级均为HL3级。硅烷改性高分子胶粘剂效果最好，层合层和层合铝接头的抗剪强度达到1000 N。丙烯酸胶带的剪切强度结果超过了一种MS聚合物胶粘剂和聚氨酯胶粘剂，表明其在需要高质量粘合的场景中具有潜在的应用前景，同时满足EN 45545-2标准规定的最高火灾危险分类HL3。
