This paper presents the finite element modelling (FEM) strategy to identify the structural response of aircraft tyres under quasi-static and taxiing load conditions. The tyre FEM was developed to simulate the aircraft tyre/ground interaction for a range of inflation pressures under vertical, lateral, longitudinal, torsional, yawed and un-yawed roll...

This paper focuses on the influence of polyphenylene sulfide (PPS) veil distribution within unidirectional carbon fibre reinforced polymer (CFRP) laminates under low velocity impact (LVI). Tests were conducted on a baseline layup of (0/90)7s, modified with various levels of veil interleaving at the middle or the outer plies. The results demonstrate...

This paper presents an experimental study on the effect of interfacial fibre orientation and interleaved thermoplastic veil on Mode II interlaminar fracture toughness of 5-harness satin woven carbon fibre reinforced polymer composite laminates. Three-point End-Notched Flexure tests were carried out to determine delamination resistance, GIIC of spec...

This paper focuses on the effect of interfacial fibre orientation and interleaved veil on the delamination migration of carbon fibre reinforced polymer laminates under Mode I loading. Double cantilever beam specimens with midplane interfacial fibre orientations of 0/0, 90/90, 0/90, 0/45 and 90/45 were tested under two conditions: one with interleav...

The understanding of the damage mechanisms for woven laminate plates under low-velocity impact is challenging as the damage mechanisms at the interface of adjacent layers are dominated by the fibre architecture. This work presents an experimental investigation of the behaviour of woven glass and carbon fibre composite laminates in a matrix of fire...

A key factor affecting the use of carbon fibre reinforced composite laminates is the low velocity impact (LVI) damage which may be introduced accidentally during manufacture, operation or maintenance of the component. Among the various failure mechanisms involved in the damage process, delamination is the dominant failure mode and may reduce the po...

A significant factor affecting the widespread use of carbon fibre and glass fibre reinforced laminates is the detrimental effect of low-velocity impact damage during manufacture and while in service. Various damage mechanisms can be involved under low velocity impact of composite materials. For unidirectional composites the identification of the De...
