Notes for Tables 5.8 - 5.10:
1. 10 x 10 x 7 mesh
2. 20 x 20 x 20 mesh
3. PW is a plate (plane stress) code and cannot compute z-direction properties
4. Summed stiffnesses of flat layers representing warp and weft fibers, with a resin layer included to
obtain the correct volume fraction. Resin layer thickness equals 0.60/0.75 x (total thickness).
5. Stacking sequence of [0/0
r
/90]
T
assumed, where 0
r
is the resin layer. B matrix ignored, which is
equivalent to averaging with reversed stacking sequence.
