Abstract: A method is provided for fabricating a unitary element, such as an exercise weight, including a composite material. The method includes providing a plurality of solid fragments including at least one non-thermoplastic material. The method further includes providing a plurality of solid particles including at least one thermoplastic polymer and/or elastomer material, at least 75% of the solid fragments having sizes in a fragment size range from zero to 32 millimeters and at least 75% of the solid particles having sizes in a particle size range from zero to 1.5 millimeters. The method further includes forming a mixture of the plurality of solid fragments and the plurality of solid particles, the mixture including 90% to 20% of the fragments by volume and 10% to 80% of the particles by volume. The method further includes molding or extruding the mixture into a unitary element through the application of heat and/or pressure.
