exotic temperature curing chamber

To see whats under this blue tarp, go down to the botom of this post and follow through a vacuum bag process. .....since it's a little cool now, I covered my bulkhead vacuum bag layup with a tarp and placed a small heater under it......

ssssssssssss

turn on the vacuum pump.....

in the bag..

cover the whole deal with a vacuum membrane

breather

top with breather material. Notice the extra breather leading to the vacuum port

layers and layers and layers

then wet it out with resin, lay in the foam piece,wet the foam surface, lay down the top layer of triaxial glass, wet out with resin, cover with another layer of peel ply, then top with perf sheeting....

glass

peeeeeel ply

lay down the peel ply.....

baggin the starboard side aft bulkhead

So here's a method of vacuume bagging bulkheads: I stretched a rubber sheet of "pond liner" over my 12ft. x 8 ft. surface so that I only need to apply a membrane over the top of my layups. the first step is to apply the mastic. Do not remove the paper tape just yet.
