ABSTRACT
The choice of manufacturing method for any composite will have a profound influence on the properties of the material produced, as it will affect the fibre volume fraction and architecture, shape, surface finish and size of component that can be achieved. As such, it is important to be sure that the correct manufacturing method is matched to the proposed application and performance. The contrast between the fresh matrix behaviour and the action of reinforcement in frp and frc is sufficient that there are few parallels between the manufacturing methods used for the respective composites. As such, the processing techniques used to produce frp and frc are discussed. Resin transfer moulding (RTM) is a factory-based process where 'dry' textile inserts preformed to the shape of the component are placed into a matching moulding tool, thermoset polymer resin is injected under pressure, and then a vacuum is applied to draw out excess air and resin.
