L'opération de 'gelcoatage' consiste à pulvériser une couche de gel coat sur un moule. L'opération de projection simultanée consiste elle à projeter un mélange de résine et de fibre de verre. Products

Chopped fiber reinforcement and catalyzed resin are deposited in the mold from a chopper/spray gun. As with lay-up, manual rolling removes entrapped air and wets the fiber reinforcement. Woven roving is often added in specific areas for thickness or greater strength.

Polyester resins are less expensive, more widely used and have good resistance to corrosion. The three main methods of fiberglass fabricating are open molding, closed molding and centrifugal molding. In open molding fiberglass fabrication, a layer of gel coat is applied and cured in a one-piece mold or structure.

1. Introduction. Natural fibres, such as flax, hemp, kenaf and sisal, are being increasingly used as reinforcements in composite materials. In comparison with conventional carbon and glass fibres, they are available in abundance, annually renewable, biodegradable and lightweight.
