Description
Summary:The evolution of offshore petroleum product technology in the last decade has convinced experts of the necessity of application of composite materials in designing both critical and supplementary constructions. The use of composites is in principal necessary in deep-water exploitations where risers and tendons are the constructions which are extremely sensitive to an increase in operation depth. The influence of water absorption, under different temperatures and thermal aging in an oven, on the elastic and strength characteristics of carbon fiber-reinforced epoxy composites is investigated by comparative tests in three point bending. The tension-tension fatigue behavior of the composites is also studied.
