Purpose. By means of experimental studies to determine the physical and mechanical properties of polymeric materials that affect the process of opening easily ejected structures.
Methods. Experimental research, comparative analysis methods.
Findings. Experimental studies were carried out to determine the physical and mechanical properties of polymeric materials. Based on the results of experimental studies, the data were obtained on the strength and deformation properties of polymeric materials (modulus of elasticity and ultimate tensile strength; modulus of elasticity and ultimate strength in bending; Poisson's ratio; shear modulus). It has been established that the diagram of tension and bending of plexiglass is characteristic for a brittle material that breaks down without yielding at low relative elongations. The tensile and bending diagram of monolithic polycarbonate has a form typical for a material subject to ductile fracture.
Application field of research. The results obtained can be used in the development of the design of an easily ejected window unit or aeration lantern of a building using polymers as a translucent filling.
