Because of its advantageous weight-to-stiffness and weight-to-strength ratios, the E-glass composite has become more attractive in the design of large wind turbine blade. In this paper, material characterization of E-glass composites was performed to determine the composite's static and fatigue properties. Also, durability and damage tolerance (D&DT) and fatigue life analyses based on a multi-scale progressive failure analysis (PFA) were performed to determine a large wind turbine blade made of E-glass composites: a) structural integrity, under 140 mph wind pressure, b) improved structural performance, under 140 mph wind pressure and c) fatigue life and the associated damage under 30-60 mph wind pressures.
