Research and modeling of a multilayer composite material using basalt fabric

Introduction. The range of use of composite materials (CM) is constantly expanding, finding application in many areas of mechanical engineering, agricultural technology, aircraft manufacturing, instrumentation, shipbuilding, in the manufacture of high-pressure containers, etc. Quite often, multilayer composites consisting mainly of one type of reinforcing material and a binder are used. Of particular interest is the use of various types of reinforcing materials - more durable in the places of maximum stress in the cross section - in a single composite. As an example, we can use glass and basalt fabrics and fibers using one type of binder. The work objective is to study properties of such a material and to model it using the finite element method.Materials and Methods. The components used are commercially available. BT-11 basalt fabric, TR-0.5 fiberglass, as well as glass mat with a density of 300 g/m2 were used as reinforcing materials. An epoxy resin of the ED-20 grade with a PEPA hardener was used as a binder...
