Teijin Techno Products Technora aramid fiber for deep-sea cable

摘要

The Japanese producer of p-aramid fibers, Teijin Techno Products Ltd., Osaka, announced that its high-performance Technora p-aramid fiber has been adopted by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for the 160 m secondary cable of a deep-sea probe named "ABISMO" (Automatic Bottom Inspection and Sampling Mobile), which is being used to explore the world's deepest oceans. Technora fiber was chosen due to its superior tensile strength, water and chemical durability, fatigue resistance to prevent degradation caused by compression or distortion as the cable is released and retrieved while the vehicle is in operation, making it ideally suited to the extremely harsh environments visited by the underwater craft.
