HI Everyone.

Here is a couple of videos of my first attempt at doing vacuum resin infusion using multiple different components in one bag. The videos are a bit long and a lot boring but enjoy :

Hopefully I have been able to put the links up above properly.

I took the components I made to Easy Composites today and Matt explained clearly where I had made some mistakes. First off, I had not allowed the resin to fully cure before removing all the components and he recommended that I should use a mix of fast and slow hardener with the epoxy to get a quicker release time or to leave everything in for much longer. As you can see on the video two of the laminates did not fully wet out to their centre and Matt explained that it was odd that it had run that far under the foam anyway. He has suggested that to do a laminate in this way using foam I should have put holes in the foam at intervals of 15mm and the holes about 1mm to1.5 mm in diameter so that the resin can easily flow to all of the materials. This is great as i am learning a lot very quickly and should hope to produce better results next time !

Any feedback would be much appreciated as it is important that I perfect the technique for doing large sized (2.30m x 1.10m) laminates of CF/Foam/CF before moving on to the next stage of my airship project.
