Ok gotta know, can I get with v-ester? Who has it, and how much?
IR is easier to add to an existing resin that requires heat to cure. UV epoxies exist, there is no doubt…but UV VER???
Will an additive work with v-ester?
Well, we are talking chemistry here. IR additive would heat up with added IR heat (ie: IR absorbing particles. Aim an IR quartz lamp at it, it heats up the particles, thereby heating the surrounding resin.) UV I don’t THINK works that way. It doesn’t create heat like IR would. I would look it up on google or wiki. I know UV curing resins are used often in optic systems.
I’m thinking heat will distort parts. My object is to have looong pot life for precise laminate placement, with flick-of-a switch cure. Cormat is part of the layup (2mm), I’m not even sure if IR, or UV would even have the penetration needed to completely cure the layup.
You can get a “summer” promoted VE which is slower cure, and then add retarder to slow it more.
This sounds like a job for infusion or out of autoclave pre-pregs, these will give you all the time in the world to place fibres and then quickly cure the part.
Moke has a point. If you need time, and precision, best do with VARTM, or prepreg (prepreg DOES have an out time, but SO easy to work with)
But you are right, IR and UV would not always get deep into the part, especially if carbon is used! Cores would be right out too.
But again, google it. UV cure epoxy yes, UV cures VER, i doubt it.
