Abstract

The factors determining the mechanical properties of plastic polymeric foams are systematized. A unification procedure for their deformation behavior in the range of strains not higher than the forced elasticity limit of the material is proposed. The universal character of the deformation process is described by a unified strain curve and ratios of the main mechanical characteristics of the material, which are independent of the chemical nature of the polymer, the structural parameters of the foam, and the temperature–rate deformation conditions. The deformation behavior of monolithic and foam plastics and inorganic plastic bodies is shown to be similar.

聚合物泡沫变形行为的普遍特征

摘要

将决定塑料聚合物泡沫的机械性能的因素进行系统化。提出了在不大于材料的强制弹性极限的应变范围内其变形行为的统一程序。变形过程的通用性由统一的应变曲线和材料主要机械特性的比值来描述，而变形比和材料的主要机械特性之比与聚合物的化学性质，泡沫的结构参数以及温度-速率变形条件无关。整体和泡沫塑料以及无机塑料体的变形行为显示出相似的结果。
