VGCF composites carbon matrix

Applied Sciences, Inc. has, in the past few years, used the fixed catalyst fiber to fabricate and analyze VGCF-reinforced composites which could be candidate materials for thermal management substrates in high density, high power electronic devices and space power system radiator fins and high performance applications such as plasma facing components in experimental nuclear fusion reactors. These composites include carbon/carbon (CC) composites, polymer matrix composites, and metal matrix composites (MMC). Measurements have been made of thermal conductivity, coefficient of thermal expansion (CTE), tensile strength, and tensile modulus. Representative results are described below. 

The thermal conductivity of vgcf has a particularly high value of about 1900 Wm K at 25°C [265] and when incorporated in a carbon matrix can produce a composite with a thermal conductivity > 1000 Wm K . ...
