β-type silicon carbide whiskers are needle-shaped single crystals. As an atomic crystal, it has low density, high melting point, high strength, high modulus, low thermal expansion rate, and excellent characteristics such as wear resistance, corrosion resistance, high temperature resistance, and oxidation resistance. It is mainly used for metal substrates and ceramic substrates. , Reinforcement and toughness of resin-based composite materials, significantly improve the performance of composite materials. The main physical performance indicators are as follows:
Closeness: 3.2g/cm2
Temperature tolerance: 2960℃
Modulus: 480GPa
Tensile strength: 20.8Gpa Hardness: 9.5【Mobs】
The silicon carbide whisker is a gray-green powder in a macroscopic view, and only when it is evenly distributed in the matrix material can it have the best effect of strengthening and toughening. For this reason, we must focus on the dispersion of whiskers during use.
