Boron fiber

The boron fiber is a man-made fiber .

It has a modulus of elasticity of up to 400 GPa with tensile strengths of around 3.5-4.0 GPa, but also high compressive strength and low shear sensitivity . This means that boron fiber is superior to carbon fiber as a high-modulus reinforcement element.

The disadvantage of boron fibers is their complicated production by chemical vapor deposition on a tungsten wire and their exclusive availability as a monofilament with a diameter of at least 60 μm. The boron fiber recrystallizes at temperatures above 600 ° C and also reacts with the tungsten core, which limits its application at elevated temperatures.
