Overview
Designed and prototyped a multi-layer energy-damping helmet liner system to reduce concussion and CTE risk in football. Combined laser-cut PETG honeycomb lattice, polycarbonate shell, silicone foam, EVA foam, and polyurethane foam layers. Validated via ANSYS Mechanical simulations (1000 J impacts at 20 m/s) and ASTM D1037 physical drop tests. Achieved a safety score of 23.6 with optimal PC-PETG-Si-EVA-PC configuration - absorbing more energy than current NFL outer helmet liners.
Key Features
- Built with modern tech stack
- Focus on user experience and performance
- Scalable architecture
Technical Implementation
This project leverages ANSYS Mechanical and Materials Science to create a robust solution. More detailed write-up coming soon.
