玻璃钢复合型材具有钢材、工程塑料所不可替代的技术特性，具有机械强度高、耐酸碱、耐腐蚀、韧性好、刚性强、抗弯强度大，重量轻等诸多优点，其应用范围与前景十分广阔。　　主要特性如下：重量为钢材的1/4；抗弯强度高于一般碳钢；它和塑料薄膜导热系数相近，不会“烫” FRP composite profiles with steel, engineering plastics irreplaceable technical characteristics, with high mechanical strength, acid and alkali resistance, corrosion resistance, good toughness, rigidity, bending strength, light weight and many other advantages, its application and prospects are very broad. The main features are as follows: the weight of steel 1/4; flexural strength higher than the average carbon steel; it is similar to the plastic film thermal conductivity, will not be “hot”
