Polyimide Coated PM Fiber (HB-P) withstands temperatures as high as 400°C short-term and 300°C continuous. It is ideally suited for medical and sensing applications where fiber must be sterilized at high temperature, or withstand the curing temperatures of the high performance laminates.
Polyimide is a high performance Polymer, widely used throughout the electronics industry. The Polyimide coating is chemically bonded to the fiber surface and is an exceptionally rugged, chemical-resistant material, which offers fiber protection when applied to a thickness of just 10μm. In comparison, a standard acrylate coating must be applied to a thickness of 40μm for a 125μm cladding diameter fiber.
HB-P is particularly suited to embedded ‘Smart-Skins’ type applications due to its low profile, which helps to maintain composite strength through a reduction in the area of the Resin Rich Zone (RRZ). The relatively thin coating, combined with the high adhesion of the glass-polyimide bond, can optimize the mechanical strain transfer in a fiber sensing system.
Fibercore’s ‘Bow-Tie’ Polarization Maintaining (PM) fiber design is capable of creating more birefringence than any other stressed design. This is simply because it is based on two opposing wedges, the most simple and efficient means of applying stress to a point.
