I tried an infusion of a flat simple spar yesterday. It was bi-axial UD cloth totalling 15mm thick approx.
Can I get everyone’s opinion on the infusion set up as I dont normally do thick UD infusions and am not convinced it penetrated throughout.
Used green flow mesh, stopping a few mm from the edge of the part - may be too fast and possibly should not have extended the spiral as far
Resin viscosity of 500cps at room temp, heated resin and mould to 40 deg C so decreased to 200cps I guess
Under tool vac ports were turned on after upper surface was wet out (1 min or so)
Would have used MTI but didnt have any to hand
Any opinions gratefully received!
