Group: Forum Members Posts: 9, Visits: 317	Hello there, I have produced several sheets of carbon using a press I have made out of two sheets of 10mm aluminium which I bolt together. My intention is to make thick slabs of carbon which I can then cut into small blocks and use them for making knife handles. The trouble I am having is small air bubbles and voids I use 12k 650g 2/2 twirl carbon 8 layers thick. I compress this stack down to 4mm using a shim on each side of my aluminium plate for a thickness guide. At first I was worried about applying too much pressure as a lot of epoxy is already forced out the sides of my press but maybe more presure might push the air out?? The questions I have are: Is there such thing as over compression will it make dry spots or weaker carbon? Will a simple case of using a bristled roller instead of a finned roller solve this? Would using thinner 6k 200g 2/2 result in no bubbles? I'm using standard el2 epoxy is there an epoxy that will give better results?
