Title:
再利用可能な注入バッグ
Document Type and Number:
Japanese Patent JP2012507416
Kind Code:
A
Abstract:
A reusable apparatus and method for forming a composite part through vacuum assisted resin transfer molding (VARTM). The reusable apparatus may be configured to vacuum seal a curable material, such as composite material, against a tool and disperse a permeating substance such as liquid resin through the curable material. The reusable apparatus may comprise a sheet of material such as rubber having a plurality of surface deviations facing the curable material and the tool. The surface deviations may provide paths for evenly distributed air flow as air is evacuated from between the sheet of material and the tool. Additionally, the surface deviations may allow the permeating substance to be evenly dispersed throughout the curable material. A vacuum outlet of the tool may be positioned between two sealing apparatuses to provide continuous vacuum suction proximate a perimeter of the sheet of material to prevent air from leaking in.
