Abstract
Disclosed is to a composite material, a structural element comprised of the composite material, an airplane wing spar and their methods of production. Some embodiments of the present invention include composite materials comprised of multiple layers of arrays of metallic bodies separated by layers of non-metallic material, wherein the orientation of metallic bodies in some metallic layers is structurally complementing to the orientation of metallic layers in adjacent metallic layers. Other embodiments of the present invention include structural elements, such as an airplane wing spar, comprised of the composite material.
Claims22
A composite material comprising:
- at least two metallic arrays of rigid oblong metallic bodies, wherein said metallic bodies have a tensile strength of 1140 MPa or greater, are at least 0.3 millimeters (mm.) thick, at least 2 mm wide and at least 10 mm long and spaces between the metallic bodies within each of the at least two metallic arrays are filled with a non-metallic filler;
- a separating non-metallic layer between each given two metallic arrays of the at least two metallic arrays, each of said separating non-metallic layers being comprised of polymer fabric or carbon fiber residing contiguously between the given two metallic arrays;
- and
- two exterior non-metallic layers comprised of polymer fabric or carbon fiber contiguously residing on an exterior side of an exterior metallic array of said at least two metallic arrays;
- wherein said at least two metallic arrays and said separating and exterior non-metallic layers are arranged in contiguous alternating layers, starting and ending with a non-metallic layer, to form a solid composite material having a non-metallic exterior surface.
A structural element comprised of:
- a component for providing structural integrity comprised of:
- first and second metallic arrays composed of an array of rigid oblong metallic bodies having a tensile strength of 1140 MPa or greater, wherein the orientation of one or more of said metallic bodies in said second metallic array is structurally complementing to the orientation of one or more of said metallic bodies in said first metallic array and spaces between the metallic bodies within each of said first and second metallic arrays are filled with a non-metallic filler;
- two exterior non-metallic layers comprised of polymer fabric or carbon fiber contiguously residing on an exterior side of said component;
- and
- a separating non-metallic layer comprised of polymer fabric or carbon fiber situated contiguously between said first and second metallic arrays;
- wherein said first and second metallic arrays and said exterior and separating non-metallic layers are arranged in contiguous alternating layers, starting and ending with a non-metallic layer, to form a solid composite material having a non-metallic exterior surface.
An airplane wing spar comprised of:
- a spar for providing structural integrity to an airplane wing comprising:
- first and second metallic arrays composed of an array of rigid oblong metallic bodies having a tensile strength of 1140 MPa or greater, wherein the orientation of one or more of said metallic bodies in said second metallic array is structurally complementing to the orientation of one or more of said metallic bodies in said first metallic array and spaces between the metallic bodies within each array are filled with a non-metallic filler;
- two exterior non-metallic layers comprised of polymer fabric or carbon fiber contiguously residing on an exterior side of said spar;
- and
- a separating non-metallic layer comprised of polymer fabric or carbon fiber situated contiguously between said first and second metallic arrays;
- wherein said metallic arrays and said exterior and separating non-metallic layers are arranged in contiguous alternating layers, starting and ending with a non-metallic layer, to form a solid composite material having a non-metallic exterior surface.
