    摘要:

    依据分子链变形和滑动观点分析了PBX材料的蠕变机理,指出聚合物蠕变是颗粒高度填充聚合物基复合材料蠕变的主要根源。用一维粘弹性蠕变损伤模型对Johnson的实验数据作进一步分析,讨论了PBX造型粉粒度等因素对PBX聚合物基复合材料蠕变损伤的影响,并指出PBX材料的蠕变损伤存在某种随机性。

    Abstract:

    A creep mechanism of PBX which is a polymer matrix composite filled by large number of solid particle is studied from the theory of deformation and sliding of molecular chain of the polymer in this paper. It is shown that the creep property of the polymer is the main factor influencing on the creep-damage properties of the composite though polymer content is so little in amount. The creep experimental results of Johnson are analyzed further by one-dimensional viscoelasticity-damage model about creep. The influence of the granularity on the creep-damage of PBX material and a certain probability of the creep-damage of PBX material are discussed initially.
