非金属复合材料(玻璃钢)与工程塑料成型件在航空、军工及其它工业中得到了日趋广泛的应用,我厂在试制某型直升机中就较多地采用了这两类材料的成型件,特别是某些大型件,如全长4米多的玻璃钢蜂窝尾梁整流罩、全长2米多的玻璃钢泡沫浮筒上盖等。这里(封二、封三)刊出的是部分成型件的图片。 Non-metallic composite materials (FRP) and engineering plastic molded parts have been widely used in aviation, military industry and other industries. Our factory made more use of molded parts of these two types of materials in the trial manufacture of certain type helicopters. In particular, Is some large pieces, such as a total length of more than 4 meters FRP honeycomb tail beam fairing, a total length of more than 2 meters FRP foam buoy cover. Here (seal two, seal three) published is part of the picture.
