Description

In the manufacture of composite structures the alignment of the reinforcing fibers can be distorted into wavy patterns due to uneven curing and shrinkage of the resin. Such wavy distortions will reduce both the strength and the stiffness of the composite structure. Yet if the fibers are intentionally formed into wavy patterns in an elastomer matrix a composite material with a stiffness that responds to changing loads and strains is produced. Such materials can be applied to uses were great flexibility is required within a limited range but high stiffness is required outside the range. This is the requirement for athletic knee braces and aircraft arrestor nets to name only two applications. Wave propagation techniques can be used to study the effects of fiber waviness on the stiffnesses of composite materials.
