Abstract
A fiber preform is infused with two differing resin systems concurrently using stacked resin delivery assemblies located along one edge of the preform.
Claims19
An Apparatus for infusing a fiber preform with at least two differing resins, comprising:
- a first resin delivery assembly capable of delivering a first resin to a first location on the fiber preform, including a first flow media;
- a second resin delivery assembly capable of delivering a second resin to a second location on the fiber preform, including a second flow media overlapping the first flow media;
- and, wherein at least one of the first and second resin delivery assemblies includes a nonporous barrier film between the first and second flow media.
An Apparatus for concurrently infusing a fiber preform with first and second differing resins, comprising:
- a first resin delivery tube located along an edge of the preform and capable of delivering a first resin to the fiber preform;
- a second resin delivery tube located along the edge of the preform and capable of delivering a second resin to the fiber preform, wherein the second resin is different from the first resin;
- first and second overlapping flow media respectively coupled between the first and second resin delivery tubes and the fiber preform;
- and, placing at least one nonporous barrier film between the first and second overlapping flow media.

A method of infusing a fiber preform with at least two differing resins, comprising:
- placing first and second resin delivery tubes side-by-side along one edge of a fiber preform;
- coupling first and second resin flow media respectively between the first and second resin delivery tubes and the preform, including overlapping the first and second resin flow media;
- placing a barrier film between an area of overlap between the first and second resin flow media
- delivering a first resin through a first resin delivery tube and a first resin flow media to the preform;
- and
- delivering a second resin through a second resin delivery tube and the second resin flow media to the preform.
3 more elements
A method of infusing a fiber preform with at least two differing resins, comprising:
- overlapping first and second resin flow media along an edge of the fiber preform;
- placing a barrier film between the overlapping first and second resin flow media to isolate the first resin from the second resin;
- and
- flowing first and second differing resins to the fiber preform respectively through the first and second resin flow media.
