The fiber undergone robust environmental testing that enables its stability against hydrogen-induced attenuation, to ensure long-term reliability of field installed optical fiber cables.
Not only does the material choice effect the actual mobility of the structure, but a series of carbon fiber "gutters" that run down the side create added structural stability.
Polypropylene fiber is a kind of all kinds offiber materials, with its perfect chemical stability and excellent technical and economic performance, is widely used in cement based composite materials.
