Fabrication of Discontinuous Graphite-Aluminum Composites via Pultrusion.

摘要

The objective of the program was to produce high strength graphite-aluminum composite bars of round and rectangular cross-sections via a pultrusion process, with the resulting composite structure consisting of discontinuous graphite fibers in an aluminum matrix. Graphite-aluminum composite wire preforms were produced using a liquid metal infiltration process. Continuous Thornel 300 polyacrylonitrile (PAN) based graphite fiber tows were infiltrated with both 6061 and 356 aluminum alloy melts.
