Dual cores were made by compression molding two outer core halves around an already molded inner core (diameter ~0.940 inch, soft compression ~0.210 inch deflection under 200 lb load). Inner and outer cores were cured at 150-400°F for 1-30 minutes. The dual cores were spherically ground to ~1.560 inch. Graphene, CNT, and graphene/CNT mixtures were introduced into the outer core. Durability was assessed by shooting cores at 175 fps in a pneumatic testing machine (PTM); 12 cores per formula were tested and mean time to fail (MTTF) was determined from a Weibull plot. Graphene/CNT-modified cores endured more shots before failure than unmodified controls.

Dual cores were made by compression molding two outer core halves around an already molded inner core (diameter ~0.940 inch, soft compression ~0.210 inch deflection under 200 lb load). Inner and outer cores were cured at 150-400°F for 1-30 minutes. The dual cores were spherically ground to ~1.560 inch. Graphene, CNT, and graphene/CNT mixtures were introduced into the outer core. Durability was assessed by shooting cores at 175 fps in a pneumatic testing machine (PTM); 12 cores per formula were tested and mean time to fail (MTTF) was determined from a Weibull plot. Graphene/CNT-modified cores endured more shots before failure than unmodified controls.
