Background. One of the promising ways to ensure high performance requirements of modern aerospace, automotive and military equipment while reducing its mass is to use polymer layered composite materials (PSKM). One of the reasons hindering the wider use of these materials is the presence of technological defects that have a significant impact on the physicomechanical characteristics of these materials, including the characteristics of resistance to deformation and fracture. Technological defects include deviations of the weight and thickness of PSKM from design values, porosity, deviations of the angles of orientation of the fabric threads in the layer, deviations of the angles of laying layers, the spread of the distance between the threads in the layer of PSKM, the waviness of the threads. The aim of the work is to study the influence of technological defects in PSCM, obtained by the technology of manual molding, vacuum bag and vacuum infusion, on their resistance to deformation and destruction, taking this influence into account in the design.
