I did my very first vac resin infusion tests yesterday and the results were quite good. I had leaks on the first tests, but it did not seem to spoil the composite plate that I was making. Probably because the leak seem to bypass the layup.
I waxed up some thick glass plate after taping the edges to keep them clean so that the acrylic filler would adhere to retain the bag later. Then I cut out two cores, one out of 1.5mm LRC (low resin content)
Soric.
The second one, I cut the same size core out of
Coremat, which is a regular fibreglassing core filler which I just happened to have in stock. I place a layer of heavy glass cloth (295 gsm) on top and bottom of each of these and positioned them on the glass plate. Then added a layer of peel ply, with the ends wrapped around pieces of spiral wrap in the usual way. I finished off the stack with a layer of infusion mesh. Inlet and outlet hoses were inserted the spiral wrap, one to pull the vacuum and the other to supply the resin.
I used a spray paint pot as a resin trap, copying "Ant's" example described in an earlier infusion thread.
I used Araldite LC3600 (it goes by several numbers??), and the ambient temperature at the time was 35 deg. C, so I didn't bother warming the resin.
I had some difficulty chasing leaks, but after they were (mostly) tracked down, the infusion went smoothly and plenty quick enough.
The bag was opened and the samples stripped from the glass this morning and look good. What was
