Infusion of resin at 30 poise to dry fabric tow
Infusion of resin at 30 poise to dry fabric tow
(OP)
Dear all,
Does anyone know how of any technique of infusing a resin film with 30 poise viscosity (lowest in can go @ 250°F) to a highly compacted dry carbon tow of 24K strands? I've tried using vacuum bag at 28 in-Hg heat to 250°F and a dwell of 30 minutes but the core is dry. Will the use of positive pressure, say 85 psi helps? Are there any other technique available? Please advice.
Thanks!

( Since you're making scrap now, at least try using glass until you get the process working. )
... Wait a sec; you're starting with resin in film form, e.g. b-staged, or you're trying to infuse a film- shaped cavity? Either way sounds like a non- starter.

Agree with ewh, the composites forum is a better bet to get infusion experts' attention.
