Embedded-object, composite-material product

Abstract

An embedded-object composite product including a solid-state mass of PET, an object embedded in the PET material mass, and a zone possessing a continuous material-density gradient in the PET material mass, with more-dense PET material residing closely adjacent the embedded object, and less-dense PET material residing more distant from that object. This product is produced effectively by non-destructively heating the PET mass from its solid state to allow it to flow as a liquid, by then pressing the object into the heated PET mass to perform object embedment and to create a declining PET-material density in the region adjacent, and progressing from adjacent, the embedded object, and by thereafter cooling the mass to re-solidify it.

1 . An embedded-object composite product comprising
 a solid-state mass of PET as an embedding-and-object-receiving (EOR) material,   an object embedded in the EOR material mass, and   a zone possessing a continuous material-density gradient in the EOR material mass, with more-dense EOR material residing closely adjacent the embedded object, and less-dense EOR material in the mass residing more distant from the embedded object.
