Mathematical Analysis of Technological Parameters for Producing Superfine Prepregs by Flattening Carbon Fibers

A mathematical model and a technique for evaluating the technological process parameters to obtain superthin prepregs by flattening carbon tows impregnated with an epoxy binder have been developed. It is recommended to simultaneously roll 25-50 carbon tows containing 400-600 monofilaments by rolls 5...

Summary:A mathematical model and a technique for evaluating the technological process parameters to obtain superthin prepregs by flattening carbon tows impregnated with an epoxy binder have been developed. It is recommended to simultaneously roll 25-50 carbon tows containing 400-600 monofilaments by rolls 50-100 mm in diameter, which is conceptually and technically consistent with possibilities of the existing equipment. The preferred viscosity range of the binder within which superthin prepregs with a thickness of 1-10 monofilament diameters are obtained has been identified. The results found significantly expand the design and technological potentialities of creating superthin skins made of carbon-fiber-reinforced plastics in comparison with the existing ones
