GENERAL METHOD OF PREPARATION OF LAMINATES

Prepare a 45 - 50 % solution of ABRON BR720 in dry NMP/ DMF/ DMAc.
Use this solution to impregnate glass-fiber fabrics and then dry at 1600C for 10 minutes to obtain a B-stage prepreg.
Stack required number of the B-stage prepregs between aluminium foils / mylar sheets.
Place the stack between heated press plates at a temperature of 1200C.
Immediately apply a pressure of 210 psi to 800 psi depending upon the thickness.
Increase the temperature progressively to 1800C in 30 minutes for stack not thicker than 3/8 in.
Cure the laminate at 1800C for 1 -2 hrs.
Remove the laminate from the hot press at 1000C and post cure it for 16 - 24 hours at 2500C.
