The limitation of non-destructive methods for the inspection of carbon fibre reinforced plastic (CFRP) composites is a major problem for many practical applications of the material, especially in the aircraft industry. This paper presents a study which is directed towards non-destructive characterization of CFRP using eddy current methods. The relationship between the signal from different type...

Most of the laboratory tests investigated the flexural performance of un-preloaded or undamaged RC beams strengthened with CFRP composites. However, in engineering applications, the structural member must carry a certain load or damage. There is a lack of systematical investigations on the effects of preload or damage level on the flexural load-carrying capacity of CFRP-strengthened RC beams. T...

Composites of carbon fiber reinforced plastics (CFRP) are being used to a greater extent in the aerospace industry due to their desired material properties. CFRP are attractive to use since they are light, strong and make it possible to integrate parts in in ways not possible in other materials. However, using CFRP is challenging since they may lead to more problems in final assembly. The aim o...

This paper describes fractographic features observed in aerospace composites failed under tensile loads. Unidirectional Carbon Fibre Reinforced Plastic (UD CFRP) and Unidirectional Glass Fibre Reinforced Plastic (UD GFRP) composite specimens were fabricated and tested in tension. The morphology of fractured surfaces was studied at various locations to identify failure mechanism and characterist...

A cradle-to-grave life cycle assessment (LCA) of structural aircraft materials has been utilised to assess and compare the total emissions produced during manufacturing, use and disposal of aerospace materials and their selected components. First, a comparison of aluminium, GLARE and carbon fibre reinforced polymer (CFRP) plates was performed to investigate the potential of lightweight composit...

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...

Hole quality plays a crucial role in the production of close-tolerance holes utilized in aircraft assembly. Through drilling experiments of carbon fiber-reinforced plastic composites (CFRP), this study investigates the impact of varying drilling feed and speed conditions on fiber pull-out geometries and resulting hole quality parameters. For this study, hole quality parameters include hole size...

Nowadays, carbon fiber reinforced plastics (CFRP) composites is widely used in the aerospace industry due to its excellent mechanical properties. In laser cutting process, high powers are used to cut materials then material melts and burns leaving edges with a high quality finish. To fulfill the high demand of cutting quality, a set of laser cutting parameters of CFRP material are studied. The ...

Abstract Since governments encourage sustainability, industries are making great efforts to reuse or recycle carbon fibre–reinforced polymer (CFRP) composites. Despite the promising early results concerning material properties of recycled CFRP, there is no published knowledge available about their machinability. In this study, drilling-induced micro and macro-sized geometrical defects were anal...

In recent years, a strongly growing demand of aeronautic industry for light weight materials like carbon fibre reinforced polymers (CFRP) motivated by economic and environmental issues is observed. The main interest of using CFRP composites is based on weight reduction, and on the high fatigue resistance capabilities. The next generation aircrafts, as the Airbus A350 XWB aim to be made of more ...
