Technologies of Metallization of Carbon Fabric and the Properties of the Related Carbon Fiber Reinforced Plastics

Abstract

Two technologies of metallization of carbon ribbons in vacuum deposition and magnetron sputtering setups are considered. Titanium is used as a metallic coating. Carbon fiber reinforced plastic samples with a coupling agent based on aminopropyl triethoxysilane are prepared for comparison. The coupling agent is also applied using the following two technologies: in the first technology, it is applied onto a ribbon and is then dried; in the second technology, it is introduced into the composition of a binder. A LUP carbon ribbon and an epoxy binder are used for investigations. The carbon fiber reinforced plastics for all technologies under study are prepared using vacuum infusion. The increase in the interlayer shear strength is found to be maximal for the metallization of the carbon on a Bulat-6 setup.
