Need hatch built
#34
Bottoms Up, using Divinycell core. When laminated it is VERY strong.
jdub, we could use the core to make the mold but that would be costly and make it hard to control the part thickness. We also want to use as little glass as possible to keep weight down. We use a grid scored material for the curved areas. The core is grid scored in both length and width directions and a glass-fiber scrim is applied. This allows the core to readily conform to the contours of molds and curved surfaces without the build-up of internal stresses in the laminate. We then lay up the outer layer of multi directional cloth with as little resin as is practical. The part is then vacuum bagged to remove any entrapped air that could weaken the structure.
Once it's cured you can easily walk across it without any damage.

depends on the area. The center of this hatch gets a 3/4 layer and 1/4 grid scored around the scoops. We'll be using a 6" rib across the front edge and a 3" rib across the back edge to provide some more rigidity.
