Materials from CES Software Database • For beam A, CFRP, epoxy matrix (isotropic) was used with 40% +/- 45 deg plies and 60% 0 deg plies. For beam B, Boron Carbide was used. • The strategy for picking the beams was as follows: Beam A: look for an optimization of low density and high shear modulus Beam B: look for an optimization of low density and high Young’s modulus • A hollow cylinder was used for both beams. Beam A used the maximum envelope, whereas beam B used a slightly smaller outer diameter. • Torsional springs were going to be added to decrease δ3, but the trade-off for decreased δ3 did not outweigh the negative consequence of increased weight.
