| Abstract: | t is very meaningful work to introduce isocyanate terminated prepolymer into solid propellant. Concerning improving mechanical properies of solid propellant, theoretical analysis is explained and experimental datas are reported.The research preliminarily shows that isocyanate terminated propolymer enhances mechanical properties of solid propellant improves its elongation rate at low temperature obviously and modificates its other performances somehow. |
