Abstract

A rocket has a nose cone capable of withstanding temperatures of at least 4000 DEG F. for over one minute, the nose cone being composed of an unfilled thermosetting resin. Suitable resins include polyurethane resins, e.g. the reaction products of polymethylene, polyphenylisocyanate, molecular weight 380-400, benzene-1,3,5-triisocyanate or toluene diisocyanate modified trimethylol propane with polypropylene glycol, molecular weight 2025, sorbitol/propylene oxide adduct, molecular weight 1500, tris-(dipropylene glycol) phosphite or propylene glycol/adipic acid/maleic acid polyester or the reaction product of toluene diisocyanate with glycerol/propylene oxide adduct, molecular weight 1000 or tris-(dipropylene glycol) phosphite, thermosetting condensation polymers of the phenol-formaldehyde type, e.g. phenol/furfural, m-cresol/formaldehyde, cresylic acid/formaldehyde and 3,5-dimethyl-penol/formaldehyde, epoxy resins from polyhydric phenols or alcohols cured with aromatic amines, cross-linked polymers of multiethylenically unsaturated compounds, cross-lined silicone resins, cross-linked acrylic resins, heat cured neoprene, furfuryl alcohol/formaldehyde resins, furfuryl alcohol/furfural resins, and cross-linked polyester resins such as condensation products of glycols with unsaturated dibasic acids modified by unsaturated compounds. Many specific resins are listed. In one example, phenol and aqueous formaldehyde are first reacted in the presence of caustic soda, neutralized with lactic acid, glycerine added and finally vacuum concentrated, the product then being heated in a mould to form a rocket nose cone. In another example a mixture of a neutral furfural aldehyde resin, with p-toluene sulphonyl chloride and ferric chloride as catalysts having different threshold temperatures, is cast into a mould and heated.
