    A customer of mine makes a foam filled honeycomb core that works well for infusion. There isn't much info about it on their website though.

    Hi Jim - I posted this link a few years ago and I think we may have an answer. While still in development stage, we are confident that by using the right materials in the appropriate configurations we can achieve the desired properties being sought.

    Infusion Grade PP Honeycomb features a composite surfacing material that is compatible with most laminating resins.

    Process Recommendations:

    Resin
    Infusion Grades
    Polyester, Vinylester, Epoxy
    Viscosity: < 200cps
    Gel Time: 45-60 minutes minimum


    Temperature:
    Process up to 150° F - 65C

    I've think even thin laminates (with slow agent) may exceed this during cure?

    That is probably why they are showing a long minimum gel time. I just did an infusion job last week with VE resin with a slow catalyst. I monitor the temperature with a IR thermometer until it reaches peak exotherm and starts downward before shutting down the vacuum, I don't think the temp got that high anywhere in the cored area but I cant quite remember. This was with a balsa core and the layup was 3 x 10.35 oz uni on the bag side, of course it may have got higher on the tool side with a bit heavier laminate and being more insulated by the mold. With standard mekp the temp gets a lot higher and I think would have exceded 150 degrees.

    Steve.
