Abstract

Test of ways of obtaining special CFRP specimens with different porosity by autoclave molding and infusion method are observed in this paper. For infusion method these results were obtained by low compression, air pumping-in to binder, lower binder input and addition of pore-forming agent. For autoclave molding these results were obtained without external pressure and molding at heat chamber with vacuum slide into the bag to 0,03–0,05 at.
