Effect of Surface Morphology on Fatigue Behaviour of Adhesively Bonded Carbon Fibres Peek Composites
In this paper, experimental fatigue behaviour of adhesively bonded PEEK composite was investigated. PEEK based materials are considered as a high performance thermoplastic materials conferring to their good mechanical properties and chemical resistant for many aggressive environments due to their semi-crystallinity property. However, it is well known that the adhesive bonding assembly of this k...
متن کاملAssessing the Strength of Carbon Fibres
Data on the strength of carbon fibres, first examined by Crowder (1994), are re-analysed. The new analysis is Bayesian and is implemented using Markov chain Monte Carlo methods. The flexibility of this approach allows an extended form of Crowder’s model to be considered, and provides more reliable measures of precision for parameter estimates. The results obtained lead to an improved understand...
متن کاملHierarchical Composites with Carbon Nanotube Grafted Fibres
Carbon nanotubes (CNTs) are excellent candidates for a new generation of high-strength, high-stiffness materials due to their low density, high aspect ratio and intrinsically superior mechanical properties. The present study investigates the feasibility of reinforcing conventional fibre/matrix composites by grafting CNTs onto the fibre surface. The approach is to exploit the CNT performance to ...
متن کاملMorphology Change and Structural Evaluation of Carbon Nanostructures
In this study, the change of porosity and roughness of carbon nanostructures, including fullerenes, carbon nanotubes and graphene was investigated according to oxidation process. The effect of oxidation was more sensible on smoother surface of nanostructures. Oxidation increases surface roughness of graphene up to 5.2% and porosity up to 35.2%. While, roughness of hummers graphene is 13....
متن کاملAccessibility and Morphology of Cellulose Fibres Treated with Sodium Hydroxide
Cellulose fibres were treated with sodium hydroxide (NaOH) to improve the accessibility of chemical reagents and the roughness of fibre surface at low temperatures. The accessibility, supermolecular structure, morphology, and physical properties of fibres were investigated using solid-state cross polarisation/magic angle spinning 13C nuclear magnetic resonance (CP/MAS 13C NMR), wide-angle X-ray...
