MATERIAL TESTING

Roush’s extensive material testing capabilities give us a unique advantage in providing our customers with optimized noise and vibration control solutions.. Our Viscoelastic Materials (VEM) Laboratory forms the core of our Noise and Vibration control consulting service, with ongoing materials research providing invaluable support for Roush's noise and vibration projects.

We evaluate adhesive, rubber, foam, plastic, mastic, enamel and coating materials to determine:
Acoustic Properties
• Acoustic absorption (Alpha Cabin, impedance tube, reverb room)
• Transmission loss (SAE J1400, reverb/anechoic rooms)
• Insertion loss (APAMAT II chamber)

Modulus and Damping Properties
• ASTM 756 vibrating beam test
• Static and dynamic impedance testing
• Creep/relaxation testing
• Complex modulus nomograms
• Temperature-frequency effects
• Test materials from -100°F to 2000°F

Structural Properties
• Load/deflection/strain measurements
• Tinius-Olsen testing equipment

Roush’s extensive material testing capabilities provide a unique advantage in our efforts to provide our customers with optimized noise and vibration control solutions.
