METHOD OF MAKING COMPOSITE MATERIAL AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2013 - IPC B29C43/34 B29C43/56 B29C70/06 B29K101/10 

FIELD: chemistry.

SUBSTANCE: suction hole is formed in the film of an elastic bag (3) for sealing space for fibre meant for saturation with a polymer resin after the beginning of saturation. The suction hole is covered with a plate (56) with holes (57). The polymer resin is sucked from space through the plate (56). In the method of making composite material, a defect formed during saturation of fibre with the polymer resin can be repaired before the polymer resin is hardened without disrupting the order and damaging the fibre. In the composite material formed from material repaired using the method described above, the repaired area is strong and there is particularly no deterioration in strength as a result of repairs after hardening. Thus, the material made using the method and the apparatus disclosed herein is preferable compared to composite material which was repaired after hardening of the polymer resin.

EFFECT: reduced deterioration of strength of the composite material owing to repair before hardening.
