对FRP夹层结构水箱失效技术原因分析

TECHNICAL REASON ANALYSIS OF SANDWICH FRP WATER TANK FAILURE

本文通过分析ＦＲＰ夹层结构水箱失效技术原因，阐明设计ＦＲＰ容器不能仅按材料强度，而必须采用限定应变准则。这是保证ＦＲＰ容器长期安全使用的技术关键。

This paper analysises technical reason of sandwich FRP water tank failure.The design of FRP vessels can't only according to material strength,must adopt the criterion of limit strain.This is a technical key for ensuring long time safety and obtaning good economic socieal benefit.
