I have three different thicknesses of divinycell, in some places butted up to each other, in my laminate stack and if I get racetracking before an area of the core gets saturated on both sides, I have a problem.
I’m learning. Resin will take the path of least resistance which is sometimes around the edge of cores.
I have ordered some of the white infusion mesh as I understand this is slower than the green mesh, with the red being fastest, maybe better for big parts. My molds are about 24" by 30" and not too deep so I figure I should slow things down with the tighter mesh but am going to try a different resin feed tee arrangement to feed the center of each core panel.
I wish there was a putty that I could use between the cores where the gaps are difficult to control. Has anyone tried mixing a batch of slower catalyst thickened epoxy to bed the edges of core while placing the laminate stack? Of course the clock is now ticking but if it worked out and all post cured after setting up, would we see shrink lines (as I do now on my flat test panels)? Or maybe lay a couple of strips of material between the cores where they butt together to act as a dam or resin stop? That seems rather fussy.
I’m using ProSet 114/210, all carbon, mostly 284 style 2x2 twill, 1/8"divinimat, 1/4" & 1/2" scored and perforated divinycell, MTI valve and hose. There are no straight lines in my parts which makes a tight fit between cores challenging.
Thanks for any ideas.
