MATERIALS

摘要

Cyclics Corp is commercializing a thermoplastic resin and targeting its use in large wind turbine structures, which are typically made of glass fibre reinforced plastics.The US firm's resin uses technology that produces cyclic compositions of polycarbonate, polyarylate and poly-butylene terephthalate. Initially, the precursors of these materials are solids, but they melt to form liquids with low viscosities. This allows them to flow into moulds easily, even those containing loadings of up to 70 percent by weight of fibre reinforcement (such as glass or carbon).
