Lightweight Solution for Composite and Multi-Material Assemblies Combines Adhesives with Fasteners

Posted By ASC, Monday, July 25, 2016

UK-based Adhesion Technologies Ltd has introduced a new system for the assembly of load-bearing composite components that, according to the company, adds up to 54% stronger adhesion, lightweighting and improved mechanical performance. The Spida Fixings and Fastening System combines mechanical fasteners with adhesives and aims to offer OEMs and their suppliers in the aerospace, automotive and transportation sectors a rapid and cost-effective means of assembling composites, plastics, and metal components using metallic or non-metallic fasteners.


A base with a large bearing area for attachments and a landing area that stops adhesives from being squeezed out below the fastener is used to bond a variety of different substrates. The concave shape of the base forms a chamber for adhesives, allowing long -chain adhesive molecules to move from 0 to 180 degrees during the cure process, resulting in better sheer, peel, cleavage, torsion, tension and compressive loading. Surface enhancement at the bond interface spreads stress across a wider substrate area, allowing OEMs to specify smaller fasteners in their designs and reducing overall weight. Thanks to redistribution of cluster stress load, stress levels in the area of fasteners are reduced, improving performance.


The first of the five different systems that will make up the range, Spida Studs, is already available with the full range to follow shortly.
