Abstract:

Usually, carbon-fiberpolymeric composite parts have been assembled manually and cured using autoclave techniques. To reduce labor costs and to enable the manufacture of composite parts larger than available autoclaves, an automated fiber placement process is being developed. In this process composite parts are fabricated one layer at a time from polymer-impregnated carbon fibers in tapes of various widths. As the fibers come into contact with the part, heat and pressure are applied to consolidate the fibers with the part, as shown in.
