The use of non-metallic composites that are durable, low cost, and lightweight is growing fast in various industries. A commonly used form these materials the shape pipes can be used, for instance, oil gas industry. Such damaged due to material loss (defects holes), erosions, more which may cause major production failures or environmental mishaps. To prevent issues, non-destructive testing (NDT...

This paper presents a study on the flexural behaviour of hybrid composite pipes reinforced with carbon and glass fibres. The progressive failure in three point bending was modelled numerically by Finite Element Analysis (FEA). FEA based model validated against experimental data. With this developed model, effects ply angle, fibre volume fraction hybridisation have been found. It is shown from r...

The objective of this study was to investigate the performance pipelines repaired with carbon-fibre-reinforced polymer (CFRP) under external pressure. pipeline experienced defects in terms thinning its local inner wall. three-dimensional finite element method used analyse collapse pressure pipes internal corrosion defects. traction–separation law and interlaminar damage criterion were applied s...

Particulated fiber reinforced polymer (FRP) composite pipes encompass unidirectional continuous glass fibers (hoop glass), resin (thermoset vinylester) matrix, chop (discontinuous short fibers), and particulate reinforcement (sand) impregnated into resin. They are categorized based on their nominal diameter, pressure class, stiffness class. Mechanical characteristics of this class materials hav...

The process of freezing of water and blockage of pipes are summarized. Current research on freezing and its applications are briefly reviewed. Design concepts are introduced for doing work by utilizing pressures caused by ice blockage. Several conceptual designs are presented for experimental setups for the isostatic pressurization of thin walled tubes. Potential practical uses of pressures gen...
