ABSTRACT

In the case of polymer matrix composites, for example, polyester resin, the latter has to be polymerized. During the solidication process, it changes from the liquid state to the solid state by copolymerization with amonomer mixed with the resin. ”e phenomenon leads to hardening. ”is can be done using either heat or achemical accelerator. ”e following pages will describe the principal processes for the manufacturing of composite parts.
