Abstract

In the manufacture of structures from polymer composite materials (PCM), defects in the form of pores are very often formed. The study of the causes of pore formation in composites began about half a century ago and is still relevant. This is due to the difficulty of preventing their formation with modern PCM manufacturing technologies, such as non-autoclave molding and the manufacture of parts of increased complexity, as well as due to the increased viscosity of the modified resins. To eliminate defects in the form of the time arising by production, it is necessary to carry out search of way of right choice of parameters of processing.
