Abstract : After many years of cheap and abundant energy availability, recent global events indicated the need for full utilization of all available energy resources (Ref 1-6). One such resource may be harvested by utilization of wind energy conversion systems. The blade materials for wind energy conversion systems are critical for several reasons. (1) The stability of the blades is related to the stiffness of the materials used; (2) The strength and long term durability of the system are linked to the static strength and fatigue endurance of the blade materials; (3) The utilization of the system depends upon the costs of the blade and the blade costs depend upon the component material and fabrication costs. One candidate material which appears to have the potential for resolution of the problem areas associated with wind energy conversion systems (WECS) and the properties required for the success of WECS is glass fiber-reinforced plastic. jg p6
