I think I need intensifiers 
The tight corners on some parts worry me somewhat(the ones you can’t actually reach with your fingers). I called with my prepreg supplier and he mentioned intensifiers.
So, what do you use as intensifier, and how do you use them?
any tips or tricks I need to know?
I currently just stuff the corners with syntactic backed 12k carbon fibre, wich seems to help, but requires extra work, material and attention…
I haven’t had hands on experience with them but for the sake of example imagine the following layup, a V. It would be difficult to get the bag all the way down to the corner, so all an intensifier is, is a piece of rubber or silicone that you put into the bag to push the fabric into these hard to reach corners. It is supposed to eliminate bridging on tight and complex geometries.
In this case it would be roughly V shaped to push the fabric into the bottom corner. It can be any shape though.
Cast them yourself. Airtech has Aircast 3600 and 3700 for that. See http://catalogue.airtech.lu/category.php?category_id=12&lang=EN
Of just cast them from cheaper silicone. Guess who can supply you with that…
We’ve used them, in the tight reach area which may commonly bridge we level the mould based on producing a casted piece specific to the area. All we do is wax up the mould and pour urethane rubber into the area. Once cured we drop it in or coat (depending) on size into some semi-perm release. When we infuse with it we wrap the piece in peel ply do it will release just in case.
Works super well, we stay clear of silicone for obvious reasons…we have a booth at the shop and for painting or clear app I just don’t like having silicone air-borne in the shop. If you can use it since nothing will stick to it but for us we had to go with rubber.
Let me know how it works out Susho or if need a pic, next time we run a piece with an insert I will be sure snap a pic and email it to you.
Time for some testing I guess
I just don’t like having silicone air-borne in the shop.
Me neither, just like the spraycans with release agents, when I started at my current job they where spraying release everywhere, just like applying release on laminating tables, and ten laminate without cleaning. Things like that are just not done.
