The technique of strengthening steel structures with Carbon Fibre Reinforced Polymer (CFRP) has attracted growing attention in research field and in practice and its environmental durability is of high importance. This paper describes an investigation on the bond characteristics between high modulus CFRP sheet and steel plates under elevated temperature exposures. Tensile tests were carried out...

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 reports analyses of a 5-degrees-of-freedom (5-DOF) carbon fiber-reinforced polymer (CFRP) robot manipulator, which has been developed for farm applications. The manipulator was made aluminum alloy (AA) and steel materials. However, to check the effectiveness CFRP materials on static free-vibration performance AA parts were replaced with CFRP. For this purpose, effects various cross-s...

Materials composed of metals and plastic composites joined through adhesive bonding are being increasingly used. However, debonding such materials may occur during manufacture or use. Non-destructive testing structures is required to evaluate their debonding. Herein, electromagnetic pulse-induced acoustic (EPAT) was used detect at the joint in composite/metal specimens. EPAT uses a pulsed excit...

In the present work, thermoplastic elastomeric nanofibers made up of a homogenous blend nitrile butadiene rubber (NBR) and Ppolycaprolactone (CL), with 80% wt rubbery component, are used to modify carbon fiber reinforced polymer (CFRP) laminate aim improving its delamination damping behavior at same time. Since nanofibrous membrane is not chemically cross-linked, fibrous morphology lost during ...

nowadays frp composite sheets for structural repair, as an efficient and cost-effective technique for restoring and upgrading the load bearing of concrete structures are have become very common. in addition to high strength to weight ratio and the use of frp sheets while structure is in use, these sheets have good fatigue resistance. furthermore, their easy application is also an undeniable adv...

Abstract Carbon fiber reinforced polymer (CFRP) with high specific strength, modulus, and other outstanding properties, which could be used in aerospace, shipbuilding, railway. The joint of carbon composite material plate metal plays an important role the overall performance structure. In this paper, a progressive damage model is developed based on laminate theory 3D Hashian theory. double bolt...
