1
yes, they can be damaged
2
1. buffing 2. polishing
3
used so the part comes off the mould easily after curing. can be sprayed, brushed, wiped on
4
1. WAX “most common”, room temp only, use rag and buff 2. Poly vinyl alcohol “leaves slight texture, must be polished 3. Parting film “solvent resistant” dissolves in water, won’t shrink
5
1. perforated “allows air and volatiles out of the lay up, prevents bleeder from sticking to the part of repair 2. Parting film “solvent resistant, parting agent for polyester or expoxy resin, will not shrink” 3. peel ply “will stick to laminate, but will pull away without difficulty”. protective layer that peels away 4.solid release film
6
1. structural “not common for structural use” 2. cosmetic “void filling” 3. protection from water/uv “protects from water egress”
7
drawing
8
to achieve proper amount of strength of the part in correct directions
9
compacting / squeezing out air between the plies under moderate heat and or vacuum prevents wrinkles, promotes adhesion
10
de-bulking required when laying up complex or heavy section components: post cure wrinkles, squeegee, vacuum bag “is the compacting or squeezing out of air and volatiles between plies or prepreg laminates under moderate heat and vacuum. PREVENTS WRINKLES, promotes ADHESION
11
film adhesives
12
two relatively thin face sheets bonded to a relatively thick light core
13
room temp cure
