Abstract

The mechanical property of lap joints can be strongly modified by tufting technique. The influence of tufting density, tufting loop and tufting direction on the fracture strength of tufted lap joints (TLJ) are mainly investigated via shearing tests. The experimental results show that lap joint strength can be much improved when the tufting density is increased. Conversely, tufting loop and tufting direction seem to have no apparently effect on the lap joint strength. However, they help to increase the specific strength of the lap joints. In this study, the samples tufted in 0º or 90º direction with a tufting density of 4.17 pts/cm2 and without tufting loops can achieve the highest specific strength. The current study revealed that the tufting technique can improve the lap joints strength within a certain range and tufting parameters need to be well designed to reduce the total material weights.

研究簇绒参数对使用簇绒技术组装的复合材料部件搭接强度的影响
簇绒技术可极大地改变搭接接头的机械性能。主要通过剪切试验研究了簇绒密度、簇绒环和簇绒方向对簇绒搭接接头(TLJ)断裂强度的影响。实验结果表明,当簇绒密度增加时,搭接强度会大大提高。相反,簇绒圈和簇绒方向似乎对搭接强度没有明显影响。不过,它们有助于提高搭接接头的比强度。在本研究中,簇绒密度为 4.17 pts/cm2 且无簇绒环的 0º 或 90º 方向簇绒样品可获得最高的比强度。本次研究表明,簇绒技术可在一定范围内提高搭接接头的强度,但需要对簇绒参数进行精心设计,以减少材料的总重量。

期刊介绍: Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes. Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
