Abstract

Whilst good impact protection using materials of 5-10 mm thickness can be achieved, the thickness of the resulting assemblage often creates difficulties of appearance, stiffness and loss of comfort. This creates problems for product developers and users. In the quest for efficient impact protection using thinner materials, research has been directed to understanding the mechanisms that provide protection. This has led to the adoption of a biomimetic approach, with consideration being given to composite materials. The research reported concerns the ability of composites to enhance impact protection without being bulky. The materials under investigation in this research are primarily commercially available in a variety of thicknesses and densities. The composites have been formed using double-sided adhesive tape. The testing work is undertaken using a customised rig that allows the forces and timescales of impacts to be recorded. The performances of the composites are compared with the test results of a variety of alternative materials, and conclusions are drawn about the mechanisms of achieving enhanced protection. Design principles are identified to assist the designers and product developers of functional apparel.
