The Role of Rheology in the Processing of Vapor Grown Carbon Fiber/Thermoplastic Composites
The work done on the processing of thermoplastics reinforced with sub-micron VGCF is reviewed in this chapter. It is feasible, and indeed easy, to produce these composites by means of conventional processing technologies. The main issues affecting the production of good-quality composites are fiber alignment, fiber-matrix adhesion and fiber dispersion. Rheological experiments can give valuable quantitative information on these issues, by illuminating the relationship between melt structure, processing and properties.
