Abstract
Systems and methods are provided for fabricating composite parts. One embodiment is a method of forming a composite part. The method includes laying up opposing composite facesheets, placing a viscous material between the facesheets, increasing a distance between the facesheets, and solidifying the facesheets and the viscous material into an integral composite part.
Claims29
A method of forming a composite part comprising:
- laying up opposing composite facesheets;
- placing a viscous material between the facesheets;
- increasing a distance between the facesheets;
- and
- solidifying the facesheets and the viscous material into an integral composite part.

A method comprising:
- placing a viscous material in contact with a first surface of a first facesheet;
- placing the viscous material in contact with a second surface of a second facesheet that faces the first surface such that the viscous material is sandwiched between the first facesheet and the second facesheet;
- drawing the second surface from the first surface in a direction away from the first surface;
- and
- solidifying the viscous material while tendrils of the viscous material remain in contact with both the first surface and the second surface.

A manufacture comprising:
- a first facesheet of fiber-reinforced polymer forming a first surface of the manufacture;
- a second facesheet of fiber-reinforced polymer forming a second surface of the manufacture;
- and
- tendrils of material disposed between the first facesheet and the second facesheet that contact the first surface and the second surface such that the tendrils are sandwiched between the first facesheet and the second facesheet.

A method comprising:
- laying up opposing composite facesheets;
- adding a core material between the facesheets;
- making the core material viscous;
- and
- drawing the facesheets apart to form the core material into tendrils between the facesheets.
