Insulation materials comprising fibers having a partially cured polymer coating thereon, articles including such insulation materials, and methods of forming such materials and articles

摘要

Insulation materials have a coating of a partially cured polymer on a plurality of fibers, and the plurality of coated fibers in a cross-linked polymeric matrix. Insulation may be formed by applying a preceramic polymer to a plurality of fibers, heating the preceramic polymer to form a partially cured polymer over at least portions of the plurality of fibers, disposing the plurality of fibers in a polymeric material, and curing the polymeric material. A rocket motor may be formed by disposing a plurality of coated fibers in an insulation precursor, curing the insulation precursor to form an insulation material without sintering the partially cured polymer, and providing an energetic material over the polymeric material. An article includes an insulation material over at least one surface.

1. An insulation material, comprising:
a plurality of fibers comprising a partially cured preceramic polymer coating thereon and disposed in a cross-linked polymeric matrix, wherein a preceramic polymer of the partially cured preceramic polymer coating comprises a material selected from the group consisting of a polycarbosilane, a polysilazane, a polysiloxane, and combinations thereof.
