【摘要】 <正>聚甲基丙烯酰亚胺(PMI)泡沫于上世纪60年代首先由Degusa公司开发成功,因其具有优异的综合性能,在相同密度的条件下,较其他泡沫塑料有更高的强度、模量,同时兼具优异的耐热性能和抗蠕变性能,现已作为夹心材料在航空、航天、铁路机车、船舶、风力发电更多还原

【Abstract】 Polymethacrylimide foam is prepared by two steps:(1)a matrix tablet obtained by polymerization of the mixture of methacylic acid,acrylonitrile,radical initiator and foaming agent;(2)the foam was prepared by heating the tablets between 187～191℃.Then,cell structure and mechanical properties of the foam was investigated briefly by using scanning electronic microscope (SEM) and electromechanical universal testing machine.更多还原
