▎ 摘　　要

NOVELTY - Method comprises adding particles to an alkaline solution, stirring the solution to cause the particles to acquire hydroxyl groups producing activated particles, dispersing the activated particles into a solvent solution, adding acetylene benzoxazine into the solvent solution, mixing the solvent solution, removing the solvent from the solvent solution to produce acetylene-benzoxazine functionalized particles, and drying the acetylene-benzoxazine functionalized particles. USE - The method is used for fabricating acetylene-benzoxazine functionalized particles, which is used in ceramic matrix composites. ADVANTAGE - The method fabricates acetylene-benzoxazine functionalized particles in one-step process, eliminates the need to separate and purify particles, then remixing them with benzoxazine monomer, produces high yield char upon pyrolysis, allows for radical polymerization of the acetylene groups to produce dense and mechanically strong silicon carbide/benzoxazine composites upon curing, and increases the high-temperature stability of the cured object made with these formulations. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a composition of matter, comprising acetylene-benzoxazine functionalized particles dispersed in a resin, optionally where the functionalized particles comprise silicon carbide and the resin comprises a benzoxazine resin.
