The illustrative embodiment comprises the sewing of fibers into a sewing substrate, which is then overmolded, to enable the manufacture of strong and lightweight articles with complex geometries.
Claims13
An article of manufacture comprising:
- a sewable solid that is made of a thermoplastic, wherein the sewable solid comprises an obverse surface and a reverse surface;
- a first thread that lies on the obverse surface of the sewable solid;
- a second thread that lies on the reverse side of the sewable solid and that also penetrates the sewable solid such that the first thread and the second thread form a first two-thread lockstitch with a first plurality of entwine points on the obverse side of the sewable solid;
- and
- an overmolding of the thermoplastic that encases the first thread, the second thread, and the sewable solid.
