Abstract
An insulation material includes a matrix comprising a reaction product formed from a silicon carbide precursor resin and a silicon dioxide precursor resin. At least one filler, such as hollow glass microspheres and/or carbon fiber is dispersed within the matrix. A rocket motor includes a case, the insulation material within and bonded to the case, and a solid propellant within the case. An insulation precursor includes a silicon carbide precursor resin, a silicon dioxide precursor resin, and the at least one filler. Related methods are also disclosed.
Claims20
A rocket motor, comprising:
- a case;
- an insulation material within the case, the insulation material comprising:
- a matrix comprising a reaction product formed from a silicon carbide precursor resin and a silicon dioxide precursor resin;
- and
- at least one filler dispersed within the matrix, the at least one filler comprising at least one material selected from the group consisting of a low density filler and an ablation enhancement filler;
- and
- a solid propellant within the case.
An insulation precursor, comprising:
- a silicon carbide precursor resin;
- a silicon dioxide precursor resin;
- and
- at least one filler material selected from the group consisting of a low density filler and an ablation enhancement filler.
A method of insulating a rocket motor, comprising:
- combining a silicon carbide precursor resin, a silicon dioxide precursor resin, and at least one filler to form an insulation precursor, the at least one filler comprising at least one material selected from the group consisting of a low density filler and an ablation enhancement filler;
- curing the insulation precursor to form an insulation material comprising the at least one filler dispersed within a solid matrix;
- applying the insulation material to an interior surface of a case of a rocket motor;
- and
- casting a propellant within the case.
