The MEE team has expertise in performing hypervelocity impact (HVI) testing and hypervelocity-related research. For a brief read about our history with HVI research, see here. All current HVI experimental research is conducted at the recently-established Texas A&M Hypervelocity Impact Laboratory (HVIL). Our current research projects deal primary with developing materials and material structures for HVI mitigation. However, some projects focus directly on the hypervelocity projectile and its interactions with water droplets, air, and debris.
Novel materials and material structures currently being investigated for enhanced HVI mitigation include (but are not limited to)
- high-performance concretes.
- carbon composites.
- layered hard/soft materials.
- additively manufactured structures.
- architected structures.
The HVIL testbed also enables the the impact of various atmospheric environments and debris, including (but are not limited to)
- water droplets.
- dust particles.
- ice particles.
- air (or other gases).
Projectile shapes include (but are not limited to)
- long rod.
- distributed impacts (down to 0.8 mm individual projectiles).
Projectile materials include (but are not limited to)
- geomaterials (e.g., sand).
