AB  - The main objective of this study is to determine tensile properties of the glass-epoxy polymer composite material. The material is glass fiber 280 g/m², 'twill woven' with 100 cm width, type - Interglas 92125, and epoxy resin type MGS L-135, where samples are molded using hand manual method with 35% fiber weight per volume. Orientations were 0/90° i ±45°. In accordance with appropriate standards, tensile strength and modulus of elasticity were determined. Beside the analysis of the results obtained during the experiment, micro-mechanical analysis of the tensile failure appearance and development was conducted based on the observed cracked surface, which led to a confirmation of all characteristic mechanisms and cracks expected for this type of material and study. Micromechanical analysis performed on the cracked surfaces of the investigated samples, has led to a definition of a structure which is more suitable for exploitation of this material in a presence of this type of external load.
AB  - Predmet i cilj ovog rada je određivanje statičkih zateznih svojstava staklo-epoksi polimernog kompozitnog materijala. Ispitivani materijal je kompozitni materijal stakleno platno 280 g/m², 'twill tkanje' širine 100 cm, tip - Interglas 92125 i epoksi smola tip MGS L-135, a uzorci su oblikovani ručnom metodom sa 35% zapreminskog udela vlakana. Ispitivane su orijentacije 0/90° i ±45°. Određeni su zatezna čvrstoća i modul elastičnosti prema odgovarajućim standardnim ispitivanjima. Pored izvedene analize dobijenih rezultata, a na osnovu izgleda prelomnih površina uzoraka izvedena je i mikromehanička analiza nastanka i razvoja oštećenja pri zatezanju čime su potvrđeni svi mehanizmi i oštećenja karakteristični za ovakvu vrstu materijala i ispitivanja. Mikromehaničkom analizom na prelomnim površinama ispitivanih uzoraka se došlo do strukture koja je povoljnija u eksploataciji pri ovakvog tipu spoljašnog opterećenja.

AB  - The object and purpose of this work is the micromechanical analysis of failures caused by mechanical tests of laminate glass-epoxy composite material in bending. The structure of glass-epoxy composite material is a glass fabric 280 g / m2, 'twill weave', width 100 cm, type - Interglas 92125 and epoxy resin type MGS L-135. Samples are shaped manual method with 35% volume fraction of fibers. Previous mechanical tests were obtained relevant data on tensile and flexural mechanical properties. By analyzing the images of fracture surfaces of larger magnification with a scanning electron microscope (SEM) will be performed micromechanical analysis that will lead to the knowledge of the mechanisms of damage and crack growth to final fracture in action bending loads.
AB  - Predmet i cilj ovog rada predstavlja mikromehanička analiza lomova nastalih mehaničkim ispitivanjima laminatnog staklo-epoksi kompozitnog materijala na savijanje. Struktura staklo-epoksi kompozitnog materijala je stakleno platno 280 g/m2, 'twill tkanje', širine 100 cm, tip - Interglas 92125 i epoksi smola tip MGS L-135. Uzorci su oblikovani ručnom metodom sa 35% zapreminskog udela vlakana. Prethodnim mehaničkim ispitivanjima su dobijeni relevantni podaci o zateznim i savojnim mehaničkim svojstvima. Analizom sa fotografija na prelomnim površinama većih uvećanja i sa skening elektronskog mikroskopa (SEM) biće izvedena mikromehanička analiza kojom će se doći do saznanja o mehanizmima oštećenja i razvoju prsline do konačnog loma pri delovanju savojnog opterećenja.
