摘要:
为了研究硝胺推进剂（挤压成型和浇注成型）和复合固体推进剂的断裂韧性，文章采用非接触类型的视频引伸仪对固体推进剂CT试样进行断裂测试，测得厚度为38 mm的3种试样断裂参数KF分别为：0.7546、0.0812、0.3368 MPa?m1/2，并且建立推进剂材料的失效评估图。发现挤压成型的硝胺推进剂断裂韧性比浇注成型硝胺推进剂和复合推进剂高，CT试样预估的失效载荷与试验结果能较好地吻合。
Abstract:
To study the fracture toughness of nitramine (in extruded and slurry cast conditions) and composite solid propellants, a noncontacting type video extensometer was applied to test solid propellant CT specimens. The fracture parametersKF for 3 samples with a thickness of 38mm were 0.7546，0.0812 and 0.3368MPa?m1/2, respectively. The failure assessment diagrams of propellant material were generated. Fracture toughness of the extruded nitramine propellant was found to be higher than those of slurry cast nitramine propellant and composite propellant. Failure load estimates of CT specimens were found to be in good agreement with test results.
