Abstract
The composite filament laminates of a composite blade are splayed at the root thereof to receive metallic inserts therebetween. A transition material having a modulus of elasticity greater than that of the inserts and less than that of the laminates is bonded therebetween to more uniformly distribute the blade loadings into the root region.
