DETERMINATION OF HEAT TRANSFER THROUGH METAL FOILS AND CERAMIC FIBER MATS DURING COMPOSITE FABRICATION

摘要

Heat transfer behavior during consolidation of metal matrix composites (MMCs) was investigated. Such composites are often fabricated by putting foils and fiber mats in a layup under pressure and heating to the consolidation temperature; the applied pressure Is then increased to the final value. In the present work, experiments were carried out in which plies made of foils and fiber mats are placed together in a layup and pressed between a hot top die and a cool lower die.
