Vacuum infusion question

Post by Mick@itc » Mon Aug 08, 2011 6:39 pm

Hi all
Been digging around info sources on vacuum infusion and noted that it was female molds that were being used. I wonder why there are no male molds in the videos? Anyone have any background info on this?
Thanks
Mick

Been in a bit of contact with a guy called Helmut and there does not seem to be any reason per se. In theory it should work the same. However one think I have noticed is that a lot of hulls are infused in two halves with the split down the middle of the hull. I found this interesting as I would have thought that the centre of the hull would be a high stress zone.

I guess it would be a high stress area but it is also a point where a large, and very strong join can be made which ends up hidden everywhere, in our types of boats that is. In smaller boats, like ski boats the seam is only visible up under the for deck, the rest is covered by the floor.

As Jim said it is possible to make the join stronger than the surrounding material.

In answer to your first question (and I may have miss read this) but the reason for using female moulds is you want the nice smooth mould finish side on the outside of your hull/deck/furniture/car body part or whatever you are making typically.
