在当前复合材料夹层结构用泡沫芯材领域中,PVC泡沫由于其良好的综合力学性能占据着主导地位,PET泡沫的应用则由于其脆性而受到一定的限制,加铝(Alcan)复合材料集团芯材事业部在其AIREX(T91基础上研制的新型PET泡沫AIREX(T92成功突破了这个弱点。本文对AIREX(T92泡沫的静、动态力学性能,高温下的力学性能以及高温下的尺寸稳定性进行了试验研究。结果表明,AIREX(T92作为一款综合性能优异的结构泡沫芯材,可以用于风能、游艇和轨道交通等各个领域。
In the current field of foam cores for composite sandwich structures, PVC foam dominates due to its good overall mechanical properties. The application of PET foam is limited due to its brittleness. Alcan composite core Material Division in its AIREX (T91 based on the development of a new PET foam AIREX (T92 successful breakthrough this vulnerability.In this paper, AIREX (T92 foam static and dynamic mechanical properties, high temperature mechanical properties and dimensional stability under high temperature The results show that, AIREX (T92 as a comprehensive performance of the structural foam core, can be used for wind energy, yachts and rail transit and other fields.
