摘　　要：在PET体系中加入0.4%的树形分子键合剂(DBA),分别考察了DBA对HMX、RDX、AP的键合效果,证实树形分子键合剂提高了PET试片、PET DBP HMX试片、PET DBP RDX试片和PET DBP AP试片的力学性能。Dendrimer bonding agent (DBA) was applied in PET systems under the existence of solid filler(HMX,RDX and AP) to form test pieces. The mechanical properties of these test pieces were detected so as to study the bonding function of DBA. Excellent mechanical properties of propellant test pieces were obtained by adding 0.4% DBA. It was found that ester group could improve the max drawing intensity (effectively) while nitril group can improve the drawing rate. Also,stress-strain curves were analyzed to (further) investigate the interfacial binding property of test pieces.
