泡沫塑料作为结构材料的使用代表了一个技术领域，随着新的出口和传统材料的替代品的出现，该技术领域正在经历快速增长。虽然生产发泡制品在材料使用和机械成本方面的经济性是显而易见的，但主要的吸引力在于开发发泡结构的特定机械性能。硬质聚氨酯泡沫塑料是最通用的候选材料之一，它可以形成在广泛的密度范围内，并具有高的比强度和韧性，如果这些性能可以得到改善，还提供了更大的潜力。本文回顾了目前的工作（1，2）
The use of foamed plastics as structural materials represents an area of technology which is experiencing rapid growth as both new outlets and replacements for traditional materials appear. Whilst the economics of producing a foamed article in terms of use of material and maclvinery costs are obvious, it is in the exploitation of the specific mechanical properties of foamed structures that the main attraction lies. Rigid polyurethane foam is one of the most versatile of the candidate materials, it can be formed in a wide range of densities and possesses a high specific strength and toughness, and yet offers greater potential if these properties could be improved. This paper reviews current work ( 1, 2)
