Abstract
Abstract A three-dimensionally latticed flexible-structure composite, including a three-dimensional lattice formed of longitudinal, lateral and vertical strings and a matrix formed by selectively impregnating the component strings of the aforementioned lattice with a molten plastic, the precursor of the matrix, and allowing the molten plastic adhering to the strings to solidify.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A three-dimensional latticed flexible-structure composite comprising: a plurality of substantially straight longitudinal strings, lateral strings, and vertical strings, each of said strings having a predetermined thickness; a three-dimensional lattice which comprises said longitudinal strings and which further comprises said lateral and vertical strings wound and zigzagged about said longitudinal strings such that adjacent lateral and vertical strings orientated in the same direction form a first pitch greater than said predetermined thickness of said lateral and vertical strings and adjacent longitudinal strings form a second pitch greater than the combined predetermined thickness of said lateral and vertical strings therebetween; and a matrix material impregnated on said longitudinal, lateral and vertical strings of said three-dimensional lattice such that said matrix material adheres to said longitudinal, lateral, and vertical strings so that said three-dimensional lattice composite has voids formed between the adjacent longitudinal, lateral and vertical strings coated with said matrix material.
Claim 2
Dependent Claim
149 words
A three-dimensional latticed flexible-structure composite comprising: a plurality of substantially straight longitudinal strings, lateral strings, and vertical strings, each of said strings having a predetermined thickness; a three-dimensional lattice which comprises said longitudinal strings and which further comprises said lateral and vertical strings wound and zigzagged about said longitudinal strings such that adjacent lateral and vertical strings orientated in the same direction form a first pitch greater than said predetermined thickness of said lateral and vertical strings and adjacent longitudinal strings form a second pitch greater than the combined predetermined thickness of said lateral and vertical strings therebetween; and a matrix material impregnated on said longitudinal, lateral and vertical strings of said three-dimensional lattice such that said matrix material adheres to said longitudinal, lateral, and vertical strings so that said three-dimensional lattice composite has voids formed between the adjacent longitudinal, lateral and vertical strings coated with said matrix material.
Claim 3
Dependent Claim
41 words
