Experimental Study of Mechanical Properties of Fiber of Deep-sea Mooring Cables
In order to learn the mechanical properties of deep-sea mooring lines, experimental studies involved in strength properties have been carried out in this thesis. In the fiber strength performance test, the small force-large deformation experimental device has been designed and optimized. As the fiber diameter is very small (about 40μm), microscope is chosen to measure the diameter. The intensity curve of fiber is divided into three typical phases. The yield strength, breaking strength and elastic modulus in initial stage can be calculated and the elastic modulus is basically a constant. With the increasing of loading rate, the breaking force reduces and gradually tends to stabilize. It has got the formula, breaking strength ∝ 1/√￣loading rate.
