Suitability assessment of the component materials of advanced composite system for aircraft structural application

The high-temperature composites have gain importance in last lately, due to their ability to withstand extreme temperatures. The study aims to obtain two classes of composite materials based on high-temp thermosetting resin and reinforcement with two-dimensional carbon fiber fabric, activated by chemical treatment, at a constant temperature of 60 °C, in two distinct chemical mixtures. The paper presents the development of numerical modelling using finite element commercial codes, based on experimental mechanical investigation (tension and three-point bending tests) and from morpho-structural point of view, optical microscopy and scanning electron microscopy analysis were performed in failure zone after mechanical testing.
