Title:
METHOD AND SYSTEM FOR RESIN-INFUSING COMPOSITE PREFORM
Document Type and Number:
Japanese Patent JP2018024229
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method and system for resin-infusing a composite preform.SOLUTION: A resin reservoir 121 has a reservoir outlet 122 and a reservoir inlet 123 located between the tool surface 111 and the reservoir outlet 122. A vacuum bagging film 130 is placed over the tool surface 111 to cover the composite preform 10 and the resin reservoir element 120. A sealed resin infusion chamber 140 is defined between the tool surface 111 and the vacuum bagging film 130. A resin is supplied along a resin flow path 142 from a resin supply portion through a composite preform 10 and through a reservoir inlet 123 to a resin reservoir 121. A pressure differential is established between the resin supply portion and reservoir outlet 122 to drive resin from the resin supply portion through the resin flow path 142, infusing the composite preform 10 with resin and collecting excess resin in the resin reservoir 121.SELECTED DRAWING: Figure 3
