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. A method of forming an embedded-object, composite-material product utilizing a solid-state mass of PET as an embedding-and-object-receiving (EOR) material, said method comprising establishing, in a prospective contact-interface region intended ultimately to exist between an embedded object and a selected, solid-state mass of EOR material, a level of heat which, when exposed to that selected mass, is sufficient to cause EOR material therein to undergo a non-destructive, reversible state change from solid to flowable-liquid,positioning an object which is to be embedded in the EOR mass, and the mass per se, in relative juxtaposition adjacent the intended contact-interface region,with said positioning accomplished, and using relative-motion pressure adjacent the intended contact-interface region, advancing the to-be-embedded object into an embedded and received condition in the EOR material mass utilizing liquid flow in the EOR mass to accommodate such embedment,by said advancing, realizing the once-intended contact-interface region between the now-embedded object and the EOR mass,following said realizing, cooling the realized contact-interface region to return the EOR material therein to a solid state, andby said cooling, creating the intended, embedded-object composite product. 2. The method of claim 1, wherein said realizing includes producing a zone possessing a continuous material-density gradient in the EOR material mass, with more-dense EOR material in the mass residing closely adjacent the embedded object, and less-dense EOR material in the mass residing more distant from the embedded object. 3. The method of claim 1, wherein said establishing is performed by directly and solely heating the EOR material mass. 4. The method of claim 1, wherein said establishing is performed by directly and solely heating the object. 5. The method of claim 1, wherein said establishing is performed by directly heating both the object and the EOR material mass. 6. The method of claim 1 which further comprises pre-embedment interposing of an expanse of fibre-strand-reinforced plastic material between the object and the EOR material mass, where the plastic included in the expanse responds to heating and cooling in the manner described for the EOR mass material. 7. A method of uniting embedding and embeddable components comprising providing, in a solid-state condition, and as an embedding component, a predetermined-volume mass of an embedding material which is non-destructively heatable and coolable to switch reversibly between solid and liquid states,heating, in relation to a selected embeddable component, at least an appropriately sized portion of the provided mass to liquefy that portion,pressing at least a portion of the selected embeddable component completely into the liquefied mass portion thereby to produce a condition of embedment wherein the overall embedding-component material and the embedded portion of the embeddable component collectively possess a volume substantially equaling the mentioned predetermined-volume, andthereafter, cooling the liquefied embedding-material mass portion to solidify it. 8. A method of forming, without material removal, a composite-material, embedded-component product comprising preparing an embedment-receiving region in a body for an embeddable component of a receiving component without removing material from that body. including heating, in relation to a selected embeddable component, at least an appropriately sized portion of the provided body to liquefy that region, andalso without performing any material-removal action, but in a manner reducing the volume of the receiving component, pressing an embedment component at least partially into the prepared embedment-receiving region to produce the desired embedded-component product, wherein, within and throughout the embedment-receiving region, an overall, intimate contact interface exists between the receiving and embedded components.
