Re: Plastics

I'm curious, what kind of loading dues the bellypan support in a traditional WCD? If I say the X-direction is the direction of forward travel, Z is up and Y is the cross product of X and Z. Am I looking at torsional loads in the Z axis or the X axis? (Or heck, even Y?) what kind of loads are typical?

I ask because we're exploring a WCD and I'm contemplating material choice for a bellypan. I've heard Travis say they use 3/16 Aluminum (I think it was a 5052 alloy). It looks like 254 just uses an 1/8" sheet of presumably 7075-T6?

We've got a couple sheets of .050" 2024-T3 and .090" 6061-O. I'm contemplating sandwiching them into a flanged isogrid, but now I'm wondering if that's even necessary. I would use the 2024 as my flanges because of the additional shear strength. The stack up would be 0.19" thick, but now that seems like a bit too much.
