Abstract

Fibre-reinforced composite materials, notably GRP and CFRP are now finding increasing use in structural applications including shipping, aircraft and aerospace as well as in large cryogenic items. This development has revived interest in the special problems associated with the testing and inspection of such materials and it is therefore an appropriate time to survey existing methods in relation both to their scientific background and their practical shortcomings. Much work on the NDT of composites has, of course, taken place in the USA but this paper aims to discuss only the main European contributions.
