Abstract

This article presents the results of experimental studies of definition the mechanical characteristics of epoxy resin and hardener without adding nanopowder and with the inclusion of nanopowders. The stability and destruction process of laminated plates made of composite material with different numbers of layers without nano-additives and with nanopowders in the binder has been studied. The results of experimental studies of the stability and destruction process of laminated plates made of composite material are presented. Experimental and numerical methods are used to estimate the carrying capacity of laminated plates. A technique has been developed for the experimental study of the deformation and strength properties of composite materials using modern test equipment. It was established that the discrepancies between the values of the critical load of four-layer samples and the critical load of three-layer samples are 2-3%, therefore, to reduce the weight, products from composite materials can be made of three-layer plates. In the ANSYS system, two-layer, three-layer and four-layer plates were modeled. The results of numerical calculation by the finite element method are presented. Comparison of the obtained experimental results with numerical values is made, the possibility of using experimental data on the mechanical behavior of layered composite materials in the design and calculation of protective screen modules is estimated.
