The potential use of carbon fibre laminate composites is limited by the weak out-ofplane properties, especially delamination resistance. The effect of incorporating titanium carbide to the mesophase pitch matrix precursor of carbon fibre laminate composites on interlaminar shear strength is studied both on carbonised and graphitised composites. The presence of titanium carbide modifies the opti...

• Recycled carbon fibres were used for laminate interlayer toughening. The commingled rCFs/Polyphenylene-sulfid showed excellent toughening performance. mode-I and mode-II fracture energies of the significantly increased by 220% 105%, respectively. This study demonstrated an attractive application recycled fibres. Exploring routes effective use (rCFs) is critical to close loop in life cycle wor...

Carbon nanotubes (CNTs) possess both remarkable optical properties and high potential for integration in various photonic devices. We overview, here, recent progress in CNT applications in fibre optics putting particular emphasis on fibre lasers. We discuss fabrication and characterisation of different CNTs, development of CNTbased saturable absorbers (CNT-SA), their integration and operation i...

The paper looks into a specific route of incorporating nanodoped materials in dry preforms to enhance the electrical conductivity of the final infused carbon fibre reinforced epoxy laminate, without affecting mechanical room temperature (RT) and hot/wet (H/W) performances. The aim is to select suitable nanodoped polymeric carriers followed by an assessment of the manufacturing, electrical and m...

This paper investigated the effect of residual thermal stresses on carbon fibre pullout by using cohesive zone modelling. The finite element method was applied to analyse the residual thermal stress components along the interface between the fibre and matrix due to curing. A comparison study on the anisotropic and isotropic material properties are considered using four typical carbon fibres, T3...

Four types of prosthetic replacement for the anterior cruciate ligament (carbon fibre, carbon fibre and Dacron composite, Dacron alone and bovine xenograft) were assessed at three, six and 12 months after implantation in the knees of New Zealand white rabbits. The synovium and both intra-articular and intra-osseous portions of the ligaments were examined macroscopically, by light microscopy and...

The soft tissue response to carbon fibre was studied histologically one and a half years after being used to reconstruct the lateral collateral ligament of the human knee. A remarkably consistent pattern was seen in the induced ligament. The basic pattern was a "composite unit", consisting of a core of carbon fibre enveloped in a concentric manner by coherent layers of fibroblasts and collagen ...

The fundamental frictional behaviour of carbon fibre tows relevant to composite fabric forming is explored. Tow-on-tool and tow-on-tow contact are considered. For tow-on-tool contact, an experiment is devised to simultaneously observe the true filament contact length and measure the friction force over a range of normal loads. Filament contact length is not constant, as would be given from an i...

Abstract Carbon fibre reinforced composites (CFRC) continue to play a key role in the growth and development of many weight sensitive industries. However, their proliferation has raised increasing concerns regarding required practices strategies deal with these expensive engineered structures at end life cycle. This brought into focus need develop more sustainable efficient recycling solutions ...

The complete relationship between the pullout load and the displacement of a fibre when it pulls out of the matrix serves as an important parameter in the design of composite materials. Many analytical models for the prediction of the behaviour of composite materials are based on the assumption of a constant friction load between the fibre and the matrix, regardless of the displacement of the f...
