Hi,
I'm working on my university research. I made a prototype of carbon fiber part. It's like cf strip I made it with wet lay-up process. However I used high temp resin for two ends and EL2 resin for the rest.  My question is that high temp. resin needs elevated temperature post‐cure cycle up to 160C while EL2 just to 60C, how can I post cure this?

I was thinking after I post cure the whole part according to EL2 procedure, I stick only the two ends in oven and continue post curing up to 160. But I hope someone has another simpler solution

Thanks

Hi, one issue of trying to heat cure one section when using CF is that carbon is a very good heat conductor so if you heat one area it is likely the heat will migrate to the rest an area of the part which only has low or medium temp resin.

Also, unless you are using prepreg it would be nearly impossible to avoid mixing the resins so you need to look at resin compatibility (which there will most likely be no manufacturer data for.
