Provided is a solid rocket motor (SRM) insulation, wherein carbon nano fibers (CNF) are blended into a polyurethane matrix so as to disperse the CNF in the polymer. The so blended material is then extruded, injection molded or sprayed on or into the desired shape. Such SRM insulation has reduced ablation over prior art insulations, resulting in reduction in weight of the insulation needed in such rockets, permitting increase of payload therein.

Rocket motor insulation

Nanoscale chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are taught as lubricants, mold release agents, and as additives to control the viscosity, lubrication, wear, and thermal properties of conventional lubricous materials. The precisely defined nanoscopic dimensions of POSS materials enable viscosity, miscibility, and thermal properties to be (increased) or reduced (decreased) as desired. A key feature to the successful tailoring of properties is the inherent thermal and chemical stability of the POSS/POS nanostructure and the ability to control its topology and chemical potential to match that of surfaces and other materials.

Lubrication via nanoscopic polyhedral oligomeric silsesquioxanes

Performance additives in high performance polymers using polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) as nanoscopic reinforcements, porosity control agents, thermal and oxidative stability aids to improve the properties of the polymers.

Polyhedral oligomeric silsesquioxane polyimide composites

A method of using nanostructured chemicals as alloying agents for the reinforcement of polymer microstructures, including polymer coils, domains, chains, and segments, at the molecular level. Because of their tailorable compatibility with polymers, nanostructured chemicals can be readily and selectively incorporated into polymers by direct blending processes. The incorporation of a nanostructured chemical into a polymer favorably impacts a multitude of polymer physical properties. Properties most favorably improved are time dependent mechanical and thermal properties such as heat distortion, creep, compression set, shrinkage, modulus, hardness and abrasion resistance. In addition to mechanical properties, other physical properties are favorably improved, including lower thermal conductivity, fire resistance, and improved oxygen permeability.

Nanostructured chemicals as alloying agents in polymers

Compositions include blends of ethylene-based polymers and polyhedral oligomeric silsesquioxanes (POSS) or polyhedral oligomeric silicates (POS), having hydrocarbon substitution and processes for producing such compositions.
