Dear sir,
I did resin infusion process for 175 x 150 mm flat plate in glass and carbon fabric. But I faced huge problem. Here i attached the photos. Kindly help me to solve this problem.
I used Vacuum pump, specification is 630 mm of Hg (or ) 24 in Hg. and its dry vacuum pump single stage. Is sufficient to do the infusion process?
Some times plate get good finishing. Some times problem will come (See the photos)
