The world’s growing appetite for wind energy is transforming wind blades into one of the hottest composite applications around. The huge build-up of wind-power generating capacity—particularly in the U.S, China, and Spain—has raised a bumper crop of new plants for manufacturing these composite parts.
New molding technologies seen at the JEC Composites Show in Paris in April promise dramatically faster cycles than are achievable with autoclaves or RTM. One novel technique rapidly heats and cools a thin tool by "floating" it on a flexible bladder—similar to a water bed—that is flooded with heat-transfer fluid.
