Abstract
Ovaj rad temelji se na mehaničkim svojstvima sendvič konstrukcija. Dan je uvid u konstituente koji čine sendvič konstrukciju i način konstruiranja u svrhu dobivanja svojstava na koja se zahtjev postavlja ovisno o primjeni. Opisane su svojstvene uloge pojedine komponente i kojim se ispitivanjima podnašaju. Prema tome je dan i pregled normi koje se koriste za dobivanje mehaničkih svojstava sendvič konstrukcija. Dobivene su dvije različite sendvič konstrukcije s korama i jezgrama različitih debljina, kao i odgovarajuće kore odvojeno. Kore su ispitane rastezno i određen je udio vlakana u polimernoj matrici. Rezultati ukazuju na povećanje rastezne čvrstoće kompozita s porastom njegove debljine. Sendviči su ispitani savojno te je utvrđeno da debljina jezgre znatno utječe na njezinu smičnu čvrstoću. Korišten je računalni program za lakše korištenje norme ASTM C393/C393M za usporedbu rezultata s ispitivanja mehaničkih svojstava. Program je dao preporučene debljine kora i jezgre za optimalna svojstva dobivenih sendviča.
Abstract (english)
This work is based on mechanical properties of sandwich constructions. An inspection has been made into the constituents from which a sandwich construction is made from. Construction with an intention of designing needed properties for a specific application was also considered. Specific roles of individual components were described as were the testings which they are submitted to. An overview of the standards applied in testing of mechanical properties of sandwich constructions has been made as well. Two sandwich panels and seperate facings, each of different thickness were tested. The facings underwent a tensile test along with determination of glass fiber content in the polimer matrix. The results indicate an increase in tensile strength of the composite with the rise of it's thickness. The sandwich constructions underwent flexural testing which determined that the shear strength of the core is drastically influenced by it's thickness. A computer program for easier use of the ASTM C393/C393M standard was used for comparation of the mechanical properties testing results. The program has calculated the recommended thicknesses of facings and the core of each individual sandwich.
