Abstract

At present, the share of polymer composite materials (PCM) in the aviation industry is increasing year by year, which is why there is a growing interest in composite molding tooling. This interest can be explained by the fact that due to affinity of materials, a formed part and rigging have similar coefficients of thermal expansion, by means of which problems of warping and occurrence of residual stresses are eliminated. In article some factors of influence on service properties of tooling for PCM manufacturing are considered, the technique of control of tooling technological properties is offered, influence of antiadhesion liquids on free surface energy of PCM is shown.
