Abstract
A method of manufacturing a resin-infused part, may include: preparing a laminate by layering a curable protective film onto a fibrous preform; infusing resin into the laminate under a vacuum, such that the resin impregnates the fibrous preform and the protective film adheres to the fibrous preform; and curing the laminate at a curing temperature.
Claims20
A method of manufacturing a resin-infused part, the method comprising:
- preparing a laminate by layering a curable protective film comprising a prepolymer layer and a resin blocking layer onto a fibrous preform, such that the resin blocking layer is disposed between the prepolymer layer and the fibrous preform;
- infusing resin into the laminate under a vacuum, such that the resin impregnates the fibrous preform and the curable protective film adheres to the fibrous preform;
- and
- curing the laminate at a curing temperature.
A method of manufacturing a resin-infused part, the method comprising:
- applying a first curable film comprising a prepolymer layer and a resin blocking layer to a caul plate;
- installing the caul plate over a fibrous preform, such that the resin blocking layer is disposed between the prepolymer layer and the fibrous preform;
- infusing resin into the fibrous preform under vacuum, such that the fibrous preform is impregnated by the resin and the first curable film adheres to the fibrous preform;
- and
- curing the fibrous preform and the first curable film.

- installing a caul plate over the first curable film;
- infusing resin into the fibrous preform under vacuum, such that the resin permeates the fibrous preform and the first curable film adheres to fibrous preform;
- and
- curing the fibrous preform and the first curable film.
