Fiber reinforced composite pultruded sheets for wind turbine blades

1 Scope

China's national standard for the composite pultruded plates used in wind turbine blades. Pultrusion has displaced hand layup for the spar caps of large blades, which are the members that carry the bending load and where most of the blade's carbon or glass fibre goes. The reason is straightforward: pulling fibre continuously through a resin bath and a heated die produces a plate with the fibres perfectly aligned, a high and consistent fibre volume fraction and almost no voids, at a rate a mould cannot match - and the blade is then built by stacking these plates. Blades have passed 100 metres, and at that length the spar cap's stiffness per unit weight determines whether the design closes at all. The standard covers the classification, coding and marking of the plates, the raw materials, the requirements, the test methods, and the inspection, marking, packaging, transport and storage provisions.

This document specifies the classification, code and marking, raw material and Materials, requirements, test methods, inspection rules, marking, packaging, transportation and storage. This document applies to composite pultruded sheets with glass fiber, carbon fiber, etc. as reinforcement materials used in wind turbine blades.
