Abstract
Unlike the traditional process of autoclave curing of prepregs, in which the fibres and the resin are pre-mixed before lay-up and moulding, the fibre reinforcement in the resin transfer moulding (RTM) process is initially dry and is often assembled outside the mould in the shape of the finished part (Figure 6.1). The fibre assembly, called a preform, is then placed in the mould and impregnated with the liquid resin which polymerises to yield a rigid composite. The preforming process thus converts the fibre reinforcement into the part geometry.
