Hey guys, i need a help  last week i start to play with infusion, first i decided to make some tests on glass  i made 3 tests and still have some tiny pinholes in my "parts", in first look they looks nice and shiny, but under sun u can see small dots inside the laminate. as i say, i did 3 tests, and after every one was better, but still not nice in every infusion i made few diferent sheets cca 20x20cm (4x200g twill weave, 1x200g+1x420g, 2x200g+soric 2mm,...) 1.INFUSION: cloth, peelply, infusion mesh, spiral tube,... Infusion was very fast, next day tiny pinholes in whole parts 2.INFUSION: the same, just excluded spiral, and made resin break, and leave the resin to degas around 10mins...better result, but still loads of pinholes in 75percent of part 3.INFUSION: infusion mesh-only small pieces under silicone connectors, i clamped out vacuum line first and wait for 20seconds, then clamped a resin line, resin was degassed for 10-15mins... 2/3 of part nearly without pinholes(maybe 1 small bubble every 8cm, but 1/3 of part, under the resin feed line is still full of pinholes  in every infusion i made leak test, and bag was always tiny, without leaks i am using all infusion stuff from EC, except vacuum pump...... I cant reach -30inHq on gauge, there is always -29 What do u think guys, can be this cause of my issues? |
