METHOD FOR COMPACTING SUBSTRATES BY CHEMICAL INFILTRATION IN GASEOUS PHASE AND APPARATUS FOR PERFORMING THE SAME |
摘要 |
FIELD: processes of chemical infiltration in gaseous phase, possibly compaction of porous substrates, mainly used for making articles of composite materials by compaction of fibrous substrates with use of matter-matrix. ^ SUBSTANCE: method comprises steps of loading substrates to loading zone of chamber; heating inner space of chamber and supplying to it gas-reagent through inlet opening in one side of chamber; preliminarily heating gas-reagent till inner temperature of chamber partially due to passing it through pipeline communicated with inlet opening for gas-reagent and placed in loading zone of chamber. Preliminarily heated gas-reagent is distributed along loading zone through one or more openings provided in lateral wall of pipeline along its length. ^ EFFECT: improved distribution and preliminary heating of gas-reagent, lowered compaction gradients between substrates arranged in different places of loading zone without lowering loading volume. ^ 12 cl, 9 dwg |
