Abstract
Official abstract text for this publication.
A composition having nanoparticles of a boron carbide and a carbonaceous matrix. The composition is not in the form of a powder. A composition comprising boron and an organic component. The organic component is an organic compound having a char yield of at least 60% by weight or a thermoset made from the organic compound. A method of combining boron and an organic compound having a char yield of at least 60% by weight, and heating to form boron carbide or boron nitride nanoparticles.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composition comprising: elemental boron; and an organic component selected from: an organic compound having a char yield of at least 60% by weight; and a thermoset made from the organic compound. 2 . The composition of claim 1 , wherein the organic compound: contains only carbon and hydrogen; contains aromatic and acetylene groups; contains only carbon, hydrogen, and nitrogen or oxygen; contains no oxygen; or contains a heteroatom other than oxygen. 3 . The composition of claim 1 , wherein the organic compound is 1,2,4,5-tetrakis(phenylethynyl)benzene or a prepolymer thereof, 4,4′-diethynylbiphenyl, N, N′-(1,4-phenylenedimethylidyne)-bis-(3-ethynylaniline), dianilphthalonitrile, or resorcinol phthalonitrile or a prepolymer thereof. 4 . The composition of claim 1 , wherein the composition comprises fibers, carbon fibers, ceramic fibers, or metal fibers. 5 . The composition of claim 1 , wherein composition is a shaped component having the elemental boron dispersed in the thermoset.
