Research on the Resistivity-Temperature Characteristic of Carbon Fiber Reinforced Wood Composite Material

This article describes the preparation of carbon fiber reinforced wood composite materials and the method of resistivity test.The resistivity change rule of the wood composite materials with different proportion carbon fiber at different temperature was investigated.The results show that carbon fiber reinforced wood composite materials is hermo-sensitive, with raise of temperature, the resistivity decreased, showing the effect of NTC, while as the carbon fiber content increase, the resistivity decreased at the same temperature.
