I am designing some water
tank access hatches and want to make them stiff (no flexing) so when I tighten the bolts, the hatch
will not flex the edges open.
I don't like the limited access that is offered by the round access hatches (Seabilt or Beckson, etc...), so I'll make my own. Two tanks
, but not integral to hull
, with three baffled compartments.
I plan on using epoxy
(Probably 17 oz biax, no mat), then I came across the idea of adding carbon fiber.
I know I can make it stiff enough if it is thick enough,but I want to keep it as thin as possible to save space.
opening will be around 12" square ( +/- a few inches) with a stainless steel
bar on the inside. When I tighten the bolt (or bolts), the bar and the lid sandwich the tank top and gasket
to form a water
I plan on making a female mold
(I have 6 hatches to make) that incorporates 1/4" deep by 3/4" wide groves (half circle-ish) that will become the stiffeners an am considering using some carbon fiber in these stiffener grooves.
The attached picture shows large holes I cut for cleaning
and repair. Final hold will be smaller, but around the 12" +/- 3" size.
Also attached is my preliminary drawing.
I've never used carbon fiber, any advice?
