Embodiment Construction

[0080] In the following description, for purposes of illustration and not limitation, specific details are set forth, such as specific embodiments, procedures, techniques, etc., in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details.

[0081] The technical features described in this application can be used to construct various embodiments of energy absorbing structural members (hereinafter also referred to as "Brockwell structures").

[0082] In one proposal, the energy absorbing structural member with enhanced load capacity per unit mass has a strip of material formed into a skeleton of a desired shape. Spaced notches are provided on the sides of the strip of material. Tensile material is woven into the desired weave around the carcass and placed in the recesses.

[0083] By providing spaced notches ...

Abstract

Structural members having enhanced load bearing capacity per unit mass include a skeleton structure formed from strips of material. Notches may be placed on the strips and a weave of tensile material placed in the notches and woven around the skeleton structure. At least one pair of structural members can be jointed together to provide very strong joints due to weave patterns of tensile material, such as Kevlar, that distributes stress throughout the structure, preventing stress from concentrating in one area. Methods of manufacturing such structural members include molding material into skeletons of desired cross section using a matrix of molding segments. Total catastrophic failures in composite materials are substantially avoided and the strength to weight ratio of structures can be increased.
