description: Fabrication of composite turbine blade usually uses resin infusion process (or VARTM/RTM, etc). In the process, resin matrix is used to fill up a fiber laminate inside a mould which has flexible polymeric bag on the top side of a rigid female mold. Most of the manufacturers make it in two pieces i.e. upper and lower skin, and fabricate them separately. Those parts are then bonded together in assembly. In this paper, a moldless technique of fabricating a small scale glass fiber reinforced polymer (GRP) wind turbine blade (WTB) is introduced which eliminates the use of rigid female mould. This method allows infusion of resin into upper skin and lower skins in a single shot. The process was monitored for its flow front pattern and corresponding fill time. Percentage of area infused over time was obtained from the result with the aid of a CAD software and compared with the analytical plot based on Darcy's law. A good agreement was found between the two results. Later, a void content analysis was carried out to determine the void distribution at both upper and lower surface of the blade. It was found that the void distribution was affected by the profile of the blade and location (inlet vs. outlet). Copyright © (2012) Asian-Australasian Association for Composite Materials (AACM).
