Brick question response
Just my opinion from all I have read on VAF. I have carbon gear leg wraps that replicate the Vans profile and use a carbon plate on the back side of the leg to form a tear shaped beam.
My conclusion from all the wise input here is the whole issue centers around input frequency and sympathetic natural frequency of the gear leg. There are many ingredients to this plot. Tire shape, tire balance, tire pressure, runway surface crack spacing, speed and last but not simple, the harmonic property of the gear leg.
My personal opinion is carbon is more of a constant over time than pine woodwork and glass. Yet, there is no silver bullet ! Most of the time my gear has no vibration, yet, rarely, I sense a little ?unhappiness? at different temps, different speeds, different runways.
Good luck 😊
