Failure Prediction of Fiber Reinforced Polymer Pipes using FEA

Abstract

Numerical study is done to predict the failure of fiber reinforced polymer pipes produced by filament winding when subjected to pure internal pressure. The analysis is done using the last ply failure technique for a four layered pipe oriented anti-symmetrically [±Ø°]2. ANSYS Composite PrepPost (version 15) is used for analysis. Three different composites were examined in this study: E-glass fiber/epoxy, carbon fiber/epoxy and aramid fiber/epoxy. Numerical analysis was further validated through experimental data in case of Eglass fiber/epoxy composite. Comparison proves a good degree of correlation. The maximum burst pressure for the three types of material is realised at [±55°]2 compared to a minimum pressure at [±0°]2 .
