Nonmetallic tools for removing flexibilized epoxy gap filler materials, and methods for removing the gap filler materials

摘要

Nonmetallic tools such as rotary bits, circular blades, and scything tools are described that may be suitable for removing cured flexibilized epoxy gap-filler materials from gaps between soft composite materials. The nonmetallic tools may be formed from various plastic or composite materials that are sufficiently hard to cut through the gap-filler material while being sufficiently soft to avoid damaging adjacent areas of soft composite materials. Methods for using the nonmetallic tools may include attaching the nonmetallic tools to a suitable machine-driven tool and contacting the nonmetallic tools to a material to be cut, shaped, or drilled.
