hello everyone. i was wondering if you guys from easy composites could exlplain more about this, i´ve being wondering
about the uses and aplication of diferent types of Core Materials
sorry if it is a stupid question :/
im really curious about this, specially for automotive parts development, which ones/how/where they should be used

Drill it with holes every 2-3 cm. Holes only need to be 2 to 3mm diameter.  On the mould contact side, score lightly between the holes too.  This gives channels for the resin to flow under the foam once it has travelled down the hole to the bottom layer.

Even if you did it in stages, youd still have to bond the foam to the cured carbon somehow as its unlikely on the second infusion that the resin would fully flow underneath.
