Tensile Behavior of photonic crystal fibres
The mechanical strength and failure behavior of two photonic crystal silica optical fibers with different diameters were investigated using tensile test. The effect of polymer coating on the failure behavior was also studied. The results indicated that all fibers failed in a brittle manner and the failure normally initiated from fiber surfaces. The failure loads observed in the coated fibers ar...
متن کاملMicro-Raman Study of the Fatigue and Fracture Behaviour of single PA66 Fibres. Comparison with single PET and PP Fibres
The micro/nano structural evolution before and after tensile loading, fatigue and ultimately, failure has been studied by Raman microspectroscopy for PA66, PP, PBO and PET single fibres and precursors, using two probes : low wavenumber collective modes at <150 cm as representative of the crystalline and amorphous chains and stretching and bending modes, as representative of the C-C bond local b...
متن کاملSize effects on tensile and fatigue behaviour of polycrystalline metal foils at micrometer scale
Tensile and fatigue properties of as-rolled and annealed polycrystalline Cu foils with different thicknesses at micrometer scale are investigated. Uniaxial tensile testing shows that with decreasing foil thickness the uniform elongation decreases for both as-rolled and annealed foils, while the yield strength and ultimate tensile strength increase for as-rolled foils, but those decrease for the...
متن کاملEffect 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 کاملTensile and Flexural Properties of Single Carbon Fibres
Polyacrylonitrile (PAN)and pitch-based carbon fibres are widely used as a reinforcement in composite materials such as carbon fibre reinforced plastics, carbon fibre reinforced ceramics, carbon-carbon composites and carbon fibre reinforced metals, because of their high specific strength and modulus. Such composites have become a dominant material in the aerospace, automotive and sporting goods ...
