On the Recycling of Carbon Fibers Reinforced Polymer Matrix Composites

摘要

The paper presents some direct and primary recycling methods of carbon fibers reinforced polymer matrix composites used in automotive industry as "high volume" components (i.e. dashboards, engine manifolds), composite bodies and structural parts in sport cars, composite bodies and parts in "low volume" applications. Some recovering possibilities of carbon fibers reinforced recycled composite materials are also described. The composite disintegration can be realized through pure mechanical methods (like selective shredding) or by pirollitic ones. Even the carbon fibers can be shredded up to a certain point. A possible recovering of carbon fibers could be the manufacture of electric conductive plastic materials (for instance, for electromagnetic compatibility) or as filler in mixtures used as anti-friction layers, for instance the automotives brake plates.
