I’ve been diving deep into composite materials used in rotor design, particularly how they affect structural integrity under load. It’s fascinating how different fiber orientations can influence fatigue life. Has anyone had success with specific materials or techniques that improved performance on their airframes?
And fiber orientation is crucial. I’ve had good results with unidirectional prepregs at high loads — what’s your go-to method?

It’s interesting how small changes can yield big results in fatigue life. I’ve had some luck with hybrid composites — they balance weight and strength beautifully. What’s been the biggest challenge you’ve faced in your testing?
