Background. One of the promising ways to ensure compliance with high requirements for the performance characteristics of modern aerospace, automotive and military equipment at reduction in mass is the use of polymeric layered composite materials. One of the reasons restraining wider use of these materials is the presence of technological defects that have a significant effect on the physicomechanical characteristics of these materials, including resistance to deformation and fracture characteristics. Among the technological defects are deviations of thread orientation angles of unidirectional layers or fabrics, as well as deviations of layer laying angles from the design values. The aim of the paper is to investigate the influence of deviation of thread orientation angles of unidirectional layers or fabrics in the layer and deviations of layer laying angles in the polyme ric layered composite material on its resistance to deformation and destruction, and to account for this influence during the design.
polymeric layered composite materials, defects in polymeric layered composite materials, micro- and macrostructure of polymeric layered composite materials, resistance to deformation and fracture
