Abstract
Ispitana je ovisnost rasteznih svojstava nezasićenog poliestera ojačanog roving staklenim vlaknima o tipu ispitnih tijela i smjeru opterećenja. Svojstva ovih polimernih kompozita određena su u skladu s normom HRN EN ISO 527-4:2008. Uspoređena su dva tipa ispitnih uzoraka, tip 1 i tip 3, rezana u dva međusobno okomita smjera. Ova dva tipa imaju velike razlike u dimenzijama te je promatran utjecaj orijentacije i tipa ispitnih uzoraka na rezultate ispitivanja rastezne čvrstoće i na modul elastičnosti. Na temelju provedenog eksperimenta i statističke analize zaključeno je da orijentacija nema značajan utjecaj na svojstva, dok je velik utjecaj prihvata i dimenzija. Na temelju analize prihvaćeno je da tip 1 daje točniji rezultat, ali uz veće rasipanje. Stoga je potrebno raditi ispitivanja na većem broju ispitnih tijela.
Abstract (english)
The dependence of stretch properties of unsaturated polyester roving fiber reinforced composites on the type of test body and the load direction was studied. The properties of these polymeric composites were determined according to HRN EN ISO 527-4: 2008. Two types of test specimens, type 1 and type 3, were cut into two mutually perpendicular directions. These two types have large differences in dimensions and the influence of orientation and type of test specimens on the results of stretching test results and the modulus of elasticity was observed. Based on the experiment carried out and the statistical analysis it was concluded that the orientation does not have a significant effect on the properties, while the influence of acceptance and dimension is great. Based on the analysis, it was accepted that type 1 gave a more accurate result, but with greater dispersion. Therefore, testing on a large number of test bodies is required.
