采用注塑成型的方式,将聚甲醛(POM)注入开孔泡沫铝(AF)中,形成一种互穿结构的复合材料(IPC)。该复合材料与纯泡沫铝和聚甲醛相比,其弯曲强度和冲击强度都有很大改善。在泡沫铝/聚甲醛复合材料中加入10%PTFE,能有效改善材料机械性能。对复合材料(IPC)进行的销-盘式摩擦试验表明,AF/POM/PTFE材料的摩擦系数比AF/POM低约12.7%,磨损量减少33.3%。对材料的磨损表面进行的SEM和EDS分析表明,复合材料耐磨性的增加与摩擦过程中形成的转移膜有关。 Using injection molding, POM is injected into open-cell aluminum foam (AF) to form an interpenetrating structure (IPC). The composite material has significantly improved flexural and impact strength as compared to pure aluminum foam and polyoxymethylene. The addition of 10% PTFE to the foamed aluminum / polyoxymethylene composites can effectively improve the mechanical properties of the material. Pin-to-disk friction tests on composite materials (IPC) showed that the friction coefficient of AF / POM / PTFE materials was about 12.7% lower than that of AF / POM and the wear loss was reduced by 33.3%. SEM and EDS analysis of the worn surface of the material showed that the increase of the wear resistance of the composite was related to the transfer film formed during the rubbing process.
