An apparatus (10) for fabricating fiber reinforced plastic structures is disclosed. In detail, the apparatus includes a mold surface (14) upon which can be supported a lay-up (16) of one or more layers (16A, 16B, 16C, 16D) of a fibrous material, and over which can be placed a fluid impervious outer sheet (26) with an inlet port (28) and having its edges (30) marginally sealed (32) upon the mold surface (14) to form a chamber (34). A vacuum outlet (35) is connected to the chamber (34) for drawing a vacuum therefrom. A resin distribution system (20) is positioned between the lay-up (16) and the fluid impervious sheet (26). The resin distribution system (20) includes a distribution sheet (40) for receiving resin from the inlet port (28) and at least one flat resin distribution line (42) connected to the inlet port (28).
L'invention concerne un appareil (10) permettant de fabriquer des structures en plastique renforc~. D'une manire plus sp~cifique, cet appareil comprend une surface de moulage (14) qui peut supporter un empilage (16) d'une ou de plusieurs couches (16A, 16B, 16C, 16D) d'un mat~riau fibreux, le tout ~tant recouvert d'une feuille ext~rieure imperm~able aux fluides (26) pourvue d'un orifice d'admission (28) et dont les bords (30) sont scell~s au niveau de leurs marges (32) sur la surface de moulage (14) de manire ~ former une chambre (34). Un orifice d'aspiration (35) est reli~ ~ la chambre (34) afin d'y cr~er un vide. Un systme de distribution de r~sine (20) est m~nag~ entre l'empilage (16) et la feuille imperm~able aux fluides (26). Ce systme de distribution de r~sine (20) comprend une feuille de distribution (40) destin~e ~ recevoir la r~sine de l'orifice d'admission (28) et au moins une ligne plate de distribution de r~sine (42) reli~e ~ l'orifice d'admission (28).
