4 Manufacture of FRP composite materials for sustainable energy technologies 

The following processing methods of synthetic libre/matrix composite materials have been used in sustainable energy technologies and are referred to where necessary. 

To improve the quality of the final composite by reducing the voids caused by air becoming trapped in the laminate and improving the consoUdation at the wet lay-up stage, a vacuum-assisted technique can be applied. The wet composite is sealed vdthin a bagging material and a vacuum is applied to the wet conposite using a vacuum pump to extract the enclosed air the polymer is then cured. 

Resin infusion technology is a process using a dry fibre laminate preform. A dry stack of fabric material is placed into a mould tool the fabric is sometimes 

The process of resin infusion is often divided into two distinct categories, based on the manner in which the resin is infused into the preform and mould cavity these divisions are not universally accepted
