Abstract
The characteristics of a polymer-composition material consisting of carbon-fabric and two types of matrices—more specifically, epoxy and organosilicon—have been considered. The main roles of the organosilicon matrix are to relax stresses arising in the parts from carbon-fiber-reinforced plastic at loads and inhibit (or stop) crack propagation. Using a tomograph, the structure of composition material was determined, a finite-element model was developed, and the stress–strain state was calculated depending on elastic characteristics of the matrices. The load factor values were calculated. It was determined that introduction of organosilicon material to the composite could decrease the stress values at the crack top, which significantly increases the service life of these materials.
