The aim of this paper was to present the determination of tensile strength Rm and modulus of elasticity Et of glass-epoxy composites at two different temperatures (at room temperature t=20°C, and at t =-50°C). Standard mechanical testing was carried out on glass woven-epoxy composite material with different structures (two specific weights of reinforcement, 210 g/m2 and 550 g/m2) and orientations (0°/90° and ±45°). Micromechanical analysis of failure was performed on a stereo microscope and SEM in order to determine real models and mechanisms of crack.
Predmet i cilj ispitivanja prikazanih u ovom radu predstavlja određivanje zatezne čvrstoće (Rm) i modula elastičnosti (EJ staklo-epoksi kompozitnih materijala ispitivanjem na zatezanje na dve različite temperature (t=20°S i t=-50°S). Ispitivanja su izvedena prema standardu na staklo-epoksi kompozitnom materijalu različitih struktura (dve specifične težine ojačanja 210 g/m2H 550 g/m2) i orijentacija ojačanja (0°/90° i ±45°). Doprinos predstavlja i mikromehanička analiza na prelomnim površinama izvedena na stereo i elektronskom mikroskopu kojom se došlo do stvarnih modela nastanka i razvoja oštećenja pri izvedenim ispitivanjima.
