An inventive solid phase forming process, and related structure, using conventional pelletized thermoplastic compositions to form the of a non-textile fabric by coining a single pellet or briquette of the polymer into an individual element in a single forming step. The steps of the process generally include: a) positioning a pellet in or adjacent to a mold cavity, and b) forcing the pellet into contact with the mold surfaces of the mold cavity to plastically deform the pellet to cause the pellet to adapt the shape of the mold cavity. The mold cavity has a shape to form the desired element, and its volume is substantially the same as the volume of the pellet. The forcing step or act preferably uses an energy and speed where the pellet superplastically deforms to substantially fill the volume of the mold cavity.
