树脂和纤维形成的复合材料,其表面的耐光、耐热、耐水、耐磨擦和耐蚀性并不令(?)满意。若不采取措施,表层树脂易受破不,会导致材料强度的下降,影响使用效果。如用玻璃钢制作的飞机头部用雷达罩,当飞机通过400公里/小时雨速飞行时,雷达罩会受到雨蚀,发生厚度不匀、透波率降低、瞄准误差增加等现象。当雨速超过500公里/小时,雷达罩就会产生灾难性破坏而失去使用价值。再如受压容器受力后,产生 Resin and fiber composite materials, the surface of the light, heat, water, abrasion and corrosion resistance does not make (?) Satisfaction. If you do not take measures, the surface resin is vulnerable to break, will lead to the decline of the material strength, affect the use effect. For example, in FRP-made aircraft head radomes, when the aircraft is flying at a speed of 400 km / h, the radome will be subject to rain erosion, uneven thickness, reduced transmissibility and increased aiming error. When the rain speed exceeds 500 km / h, the radome can cause catastrophic damage and lose its use value. Another example is the pressure container after force
