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.
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.
