Life prediction for carbon fibre filament wound composite structures

Carbon Fibre Composite Bone Plates

We compared the mechanical properties of carbon fibre composite bone plates with those of stainless steel and titanium. The composite plates have less stiffness with good fatigue properties. Tissue culture and small animal implantation confirmed the biocompatibility of the material. We also present a preliminary report on the use of the carbon fibre composite plates in 40 forearm fractures. All...

Adapting carbon nanotubes for fine composite structures

Although defective, commercially-available, CVDgrown, multi-walled carbon nanotubes are widely used for polymer nanocomposites due to their availability and low cost. However, to use these materials effectively, they must be disentangled, and chemically modified in order to produce high quality composites. This paper shows that such nanotubes can be disentangled by cutting; abrupt, repeated exp...

Compressive response of a 3D non-woven carbon-fibre composite

The compressive response of a three-dimensional (3D) non-interlaced composite comprising three orthogonal sets of carbon fibre tows within an epoxy matrix is analysed. First, the compressive response is measured in three orthogonal directions and the deformation/failure modes analysed by a combination of X-ray tomography and optical microscopy. In contrast to traditional unidirectional and two-...

The Effect of Processing Parameters on Structural Property for Filament-wound Composite Pressure Vessels

1 Introduction Filament winding is a popular production technique for composite structures. Cylinder pressure vessel with elliptical dome is an efficient product which can make full use of tensile strength of fiber. To achieve the most efficient use of the reinforcement material the fiber should be placed in the maximum load directions or in geodesic path. This is not always achievable as the f...
