Peter Byrnes from their position as the natural matrix in ‘advanced‘ composites for sUl;h fields as aerospace. Dr McMahon gives some indication of the nature of this challenge in his chapter on fibre-reinforced thermoplastics. He acknowledges the problem of their low fibre contents, with the associated possibi

Peter Byrnestate in the resin matrix, and this is discussed in the context of the total polymer processing operation. The concept of a prepreg is a broad one, but this chapter focuses on ‘classical’ materials, and the problems described relate to electrical grade laminates, which have to meet extremely strict
