FORGED COMPOSITE is produced by S S S Sheet M M M Moulding C C C Compound process with carbon fibres (opposited traditional glass fibre SMC) It uses pre-fabricated sheet material made

• f vinylester resin and short length carbon fibres (chopped fibers).

FORGED COMPOSITE should not be confused with traditional GF-SMC. The primary advantages of carbon fibers in FORGED COMPOSITE are higher modulus and lower specific gravity relative to glass fibers. The modulus of commercial-grade carbon fibers is more than four times higher than E-glass fibers!
