Abstract

The use of composite materials in industry is growing due to various technological advances in composite materials accompanied by improvements in the structural adhesives used to bond them. Fibre metal laminates (FML's) are hybrid composite structures based on thin sheets of metal alloys and plies of fibre-reinforced polymeric materials. The fibre/metal composite technology combines the advantages of metallic materials and fibre-reinforced matrix systems. The aim of the present study is to use a concept similar to that used in FML to increase the peel strength of composite materials and increase the joint strength of hybrid laminates aluminium carbon-fibre adhesive joints. Carbon fibre-reinforced plastic (CFRP) composites were modified by including one or several aluminium sheets during the laminate manufacture to enhance the composite through the thickness properties. The objective was to identify the joint configuration that gives the best joint strength improvement in relation to the CFRP only reference joint. An adhesive developed for the aeronautical industry was used to manufacture single lap joints for tensile testing. Experimental and numerical studies were undertaken on modified CFRP joints to investigate the joint strength of different lay-up solutions to prevent delamination of adherends.

不同铺层构型混合层合板铝碳纤维接头的试验与有限元研究

由于复合材料的各种技术进步以及用于粘合它们的结构粘合剂的改进，复合材料在工业中的使用正在增长。纤维-金属层压板（FML）是基于金属合金薄板和纤维增强聚合物材料层的混合复合材料结构。纤维/金属复合材料技术结合了金属材料和纤维增强基体系统的优点。本研究的目的是使用与FML中使用的概念类似的概念来提高复合材料的剥离强度，并提高混合层压板铝碳纤维粘合接头的接头强度。在层压板制造过程中，通过加入一块或几块铝板对碳纤维增强塑料（CFRP）复合材料进行改性，以增强复合材料的厚度性能。目的是确定与仅使用CFRP的参考接头相比，能够提供最佳接头强度改进的接头配置。一种为航空工业开发的粘合剂被用于制造用于拉伸测试的单搭接接头。对改性CFRP接头进行了实验和数值研究，以研究不同铺层方案的接头强度，以防止被粘物分层。
