Abstract
A hybrid composite structure includes a molded thermoplastic composite component and a laminate thermoplastic composite component co-welded together. The molded component is reinforced with discontinuous fibers, and the laminate component is reinforced with continuous fibers.
Claims25
A method of making a composite structure, comprising:
- molding a thermoplastic resin first component reinforced with discontinuous fibers;
- laying up a thermoplastic resin second component reinforced with substantially continuous fibers;
- and
- co-welding the thermoplastic resin first and second components.
1 more element
A method of making a composite structure, comprising:
- compression molding a fiber reinforced, thermoplastic component having a web and at least one flange integral with the web;
- laying up a fiber reinforced, thermoplastic cap;
- placing the thermoplastic cap on the flange;
- and
- joining the thermoplastic cap with the flange.
2 more elements
A method of making a composite beam, comprising:
- molding a beam using thermoplastic prepreg flakes;
- producing at least one cap using thermoplastic prepreg tape;
- and
- co-welding the cap and the beam.
1 more element
A hybrid composite structure, comprising:
- a first thermoplastic resin component reinforced with discontinuous fibers;
- and
- a second thermoplastic resin component reinforced with continuous fibers and joined to the first thermoplastic resin component.
A composite structure, comprising:
- a composite beam formed of a thermoplastic resin reinforced with randomly oriented, discontinuous fibers, the beam including a web and a pair of flanges integral with the web;
- and
- at least one composite cap joined to one of the flanges, the composite cap formed of a thermoplastic resin reinforced with continuous fibers.
