“…Composite materials derived from epoxy resin and carbon fibers are being extensively employed in aircraft industries because of their strength, high modulus and light weight [1][2][3][4] . Carbon fiber reinforced plastic (CFRP) offer their greatest advantage over isotropic materials when their fiber axes are aligned in the direction of the principal stress 5 .…”

Carbon fiber reinforced plastic (CFRP) composites have been extensively used in fabrication of primary structures for aerospace, automobile and other engineering applications. With continuous and widespread use of these composites in several advanced technology, the frequency of failures is likely to increase. Therefore, to establish the reasons for failures, the fracture modes should be understood thoroughly and unambiguously. In this paper, CFRP composite have been tested in tension, compression and flexural loadings; and microscopic study with the aid of Scanning Electron Microscope (SEM) has been performed on failed (fractured) composite surfaces to identify the principle features of failure. Efforts have been made in correlating the fracture surface characteristics to the failure mode. The micro-mechanics analysis of failure serves as a useful guide in selecting constituent materials and designing composites from the failure behavior point of view. Also, the local failure initiation results obtained here has been reliably extended to global failure prediction.

“…Although cylinder tubes may fail in multiple ways under combined axialpressure loadings (Marinucci and de Andrade, 2006;Tafreshi, 2004;Wiggenraad et al, 1996), delamination-type failure was commonly encountered in thick composite cylinders (Bai et al, 1997;Rasheed and Tassoulas, 2001;Zhao et al, 2000). Potential delamination of the cylinder such as annular delamination (Kachanov, 1988), strip-type delamination (Timoshenko and Gere, 1961) and buckling of the delamination regions were numerically investigated by Theotokoglou (Theotokoglou, 2006).…”

There is accelerating interest in composite risers for deepwater applications. Composite risers offer much higher strength to weight ratios over metallic risers but there is less experience of their behavior in deepwater environments. A general review on current developments specific to composite risers highlighting the remaining challenges and the applications, design evolution, state-of-the-art modeling and experimental techniques is lacking. This paper provides such a review on fiber-reinforced polymer composite risers. The major issues for composite risers are addressed including the complicated combination of loads under harsh deep sea environment, the lack of long-term material degradation database for assessing the reliability of these riser systems and the need of effective numerical models to fully account for complex realistic loading configurations. The paper also highlights current gaps for design and application of composite risers in offshore technology and promising future research areas to help expand their utilization in deeper water.
