To repair corroded subsea pipelines, composite fiber-reinforced polymer (CFRP) patches are often attached to the defected area. The aim of this paper is present a method assure if strength repaired pipelines sufficient enough sustain burst pressure loads. A computational model for predicting with CFRP presented. An algorithm artificial neural networks (ANN) applied. geometry corrosion damage de...

A study was conducted on the reinforcement of cross-laminated timber (CLT) concrete composite floors with carbon fiber reinforced plastic (CFRP) to improve its mechanical performance and reliability in wood structures. four-point bending test evaluation completed three types produced different ratios (33%, 66%, 100%) entire surface tensile portion. An increase ratio led an increased capacity a ...

In the automotive industry, being lightweight has become an important design factor with enhancement of environmental regulations. As a result, many studies on application composite materials are in progress. Among them, interest carbon materials, such as sheet molding compound (C-SMC) and carbon-fiber-reinforced plastic (CFRP), which have excellent strength stiffness, is increasing. However, C...

Increased electrification of aircraft power systems has been widely presented as a route toward meeting environmental and emissions targets for performance, via more-electric future hybrid-electric concepts. In parallel, the superior mechanical performance carbon fiber reinforced polymer (CFRP) resulted in its increasing use structures. The relatively low electrical conductivity CFRP compared t...

Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated CFRP structures, it is, however, difficult to detect damage such as delamination, matrix cracks, and local fiber breakages caused by low velocity impact loading In the previous study in 2009, Time Domain Reflectometry (TDR) method was applied...

Abstract Carbon-fibre-reinforced polymer (CFRP) composites are promising materials for non-metallic pipe applications in the oil and gas industry owing to their high corrosion resistance, specific strength stiffness. However, CFRP has poor barrier performance meaning that a liner be inserted. Graphene-based nanomaterials have been demonstrated improve properties thermoplastic polymers, thus, CF...

The use of carbon-fibre-reinforced polymers (CFRP) laminates in structural applications where high strength-to-weight and high stiffness-to-weight ratios are required is wellestablished. However, because of structural distortions induced by moisture absorption effects, polymer matrix composites are not yet definitely considered suitable candidate for ultra-high precision engineering application...

Experimental method was employed to investigate mechanical characterization of carbon fiber reinforcement polymer (CFRP) composite beams at different temperatures. The experimental research is mainly based on the vibration response measurement by using technique electronic speckle pattern interferometry (ESPI), which can provide visualization vibrating information represented as fringe patterns...

Shape, thickness and stacking sequence optimisation of a damage tolerant hybrid (GFRP-CFRP) composite laminate is performed using the commercial Optistruct solver. The results study are compared to both benchmark non-damage CFRP (without protective surface GFRP plies known as type 1 laminate) traditionally optimised CFRP-GFRP (having X shape 2 laminate), designed tested in previous study. manuf...
