Review of Prepreg Technology

  • Chapter
Developments in Reinforced Plastics—5

Summary

This chapter discusses the prepreg process in fibre-resin composites. The central feature of the process is the production of a partially crosslinked state 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 requirements. The raw materials (reinforcement and resin) are briefly outlined, together with an account of the behaviour of prepregs during subsequent manufacturing, especially at the pressing stage.

The principal emphasis is on prepreg formation, and on the characterisation of properties, together with various technological problems. These latter relate mainly to impregnation and to the supply of heat within the dryer. Attention is given to undesirable defects occurring in prepregst and to technological calculations relating to weighty and to pre-curing. Computer-aided control is also mentioned.

The extent of pre-cure is important, and several diagnostic test methods are discussedy along with the effect of the state of pre-cure on behaviour in the press, as well as on the final material properties. Trials to simulate the many influences on prepreg properties are briefly outlined. Finally, probable future trends are discussed. A dramatic change in prepreg processing technology is not expected, but innovations will continue to produce improvements.
