Abstract
Official abstract text for this publication.
A method of fabricating a woven fiber preform that is impregnated with a matrix-precursor resin, the resin, in the raw state, presenting a glass transition temperature Tg 0 , includes: impregnating yarns or strands with the resin; feeding a loom with the impregnated yarns or strands maintained at a temperature in the range Tg 0 to Tg 0 +10° C.; and weaving the yarns or strands in the loom in order to obtain the resin-impregnated woven fiber preform.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of fabricating a woven fiber preform that is impregnated with a matrix-precursor resin, said resin, in the raw state, presenting a glass transition temperature Tg 0 , the method comprising: impregnating yarns or strands with the resin; feeding a loom with the impregnated yarns or strands maintained at a temperature in the range Tg 0 to Tg 0 +10° C.; and weaving the yarns or strands in the loom in order to obtain the resin-impregnated woven fiber preform. 2. A method according to claim 1 , wherein the yarns or strands are made of carbon or of silicon carbide. 3. A method according to claim 1 , wherein the resin is a thermosetting epoxy resin. 4. A method according to claim 1 , wherein the resin-impregnated yarns or strands are present in a refrigerated enclosure feeding the loom with resin-impregnated yarns or strands. 5. A method according to claim 1 , wherein the yarns or strands are woven by three-dimensional weaving.
