Abstract
An apparatus and method for securing fittings to composite structures such as those composites formed out of resin-embedded fibers is disclosed. The invention includes the use of support structures wrapped around the fittings such that the support prevents the fitting from movement when a compression load is applied thereto. The support serves to transfer the force of the compression load into the entire body of the composite structure so that the force will be absorbed by the structure. In one embodiment of the invention, the support structure comprises a composite fiber tow formed of high tensile strength fibers impregnated with a matrix material. The composite fiber tow is fibers wrapped around the fittings to form suspension strands. As the matrix material cures the composite fiber stiffens to hold the fitting in place against the composite structure.
