Compression resin transfer moulding (CRTM), schematically described in Fig. 7.2, is another variation of RTM, in which the rigid upper mould is partially closed, maintaining a given cavity thickness greater than the final part thickness. The desired quantity of resin is then injected. Finally the mould is closed to its final position, compacting the preform to its final thickness, and establishing a compression-driven flow which pushes the resin into the...
