Abstract
A previous paper [1] has discussed some simplified models that describe the impact behaviour of polymer composite sandwich beams. The models were used as part of a final-year undergraduate course in impact engineering at the University of Liverpool. This paper relates these beam models to five composite constructions, namely, a surfboard, a dinghy, a solar car, a train and a helicopter. The aim of the paper is to integrate issues concerning composite materials, manufacture and structural design. The beam models are used to critique the selected product designs and to identify the effects of improvements to material properties with a view to improving beam, and hence, product performance.
