Abstract
A method of repairing a composite component having a damaged area including: laying a composite patch over the damaged area; activating the shape memory polymer resin to easily and quickly mold said patch to said damaged area; deactivating said shape memory polymer so that said composite patch retains the molded shape; and bonding said composite patch to said damaged part.
Claims67
A method for repairing manufactured parts having a damaged area comprising:
- a. preforming a repair material into a desired shape, said repair material comprising a shape memory polymer;
- b. activating said shape memory polymer such that said preformed repair material becomes soft;
- c. deforming said preformed material into a shape adapted for said repairing, wherein said deforming is achieved by mechanical means;
- d. deactivating said shape memory polymer while maintaining said repair material in its deformed state;
- and
- e. bonding said deformed repair material to said damaged area of said manufactured part.

3 more elements
A method of joining a plurality of manufactured parts together comprising:
- a. juxtaposing said parts so that at least one joint area is formed;
- b. providing a preformed shape memory material;
- c. activating said preformed shape memory material and applying it to said joint area;
- d. deforming said preforming shape memory material into a desired shape, wherein said deforming is accomplished by mechanical means;
- e. deactivating said shape memory material while maintaining it in said deformed shape;
- and
- f. bonding said deformed shape memory material to said joint area.
