- Catalyst-Binder Molding of Sustainable Barriers for Faster Curing
A catalyst-enhanced binder speeds curing of waste material outside a press, boosting throughput while enabling tunable barrier density and strength.
- Reinforced Waste-Material Barriers With Tunable Impact Structure
Waste-filled barriers use a catalyzed polyurethane binder, reinforcement, and tunable density to resist breakage while meeting certification needs.
- Waste-Material Crash Cushion Composition for Custom Impact Barriers
Waste material bound with polyurethane forms crash cushions with tunable density and shape, improving impact resistance over brittle concrete barriers.
- Vibroacoustic Metamaterial Barrier for Low-Mass Sound Insulation
Tuned mechanical resonators create stop bands that cut sound transmission with less barrier mass and support partially transparent noise screens.
- Sectional Resonator Noise Barrier for Low-Height Sound Diffraction
Sectional resonator channels fold sound paths to keep barriers lower while maintaining vehicle noise diffraction and resonance.
