FRP／PVC复合管应力分析与强度校核

Stress Analysis and Strength Check of FRP/PVC Composite Pipe

针对内层材料是ＰＶＣ塑料、外层材料是玻璃布聚脂复合材料ＦＲＰ的复合管系，采用简化的力学模型，计算在复原力、内压及自重作用下的应力分析以及温度改变引起的内部热应力，并推荐了强度理论。

For composite pipes whose internal material is PVC and external material isglass cloth polyester FRP,a simplified model is adopted to compute the stress under recovery forces,internal pressure,weight and internal thermal condition。Suitable strength theories are advised for strength check。
