Abstract
Characteristics of composite materials (stiffness, resistance, thermal expansion, etc.) can vary depending on the type of the applied material, quantity, fibre orientation angle, etc. The choice of material depends on the service life needed, product shape complexity, computation of optimal characteristics of composite materials, etc. In some cases, the best results can be achieved using a combination of composite and traditional metal materials. This paper studies shafts obtained by a combination of aluminium and different composite materials - carbon fibres/epoxy resin, glass fibres/epoxy resin, and aramide fibres/epoxy resin.
Sažetak
Karakteristike kompozita (tj. krutost, otpornost, termičko širenje i dr.) mogu da variraju zavisno od vrste primenjenog materijala, količine, ugla orijentacije vlakana i dr. Izbor materijala zavisi od zahtevanog radnog veka, složenosti oblika proizvoda, veštine proračuna optimalnih karakteristika kompozita i dr. U nekim slučajevima najbolji rezultati mogu biti postignuti korišćenjem kombinacije kompozita i tradicionalnih metalnih materijala. U radu su analizirana vratila dobijena kombinacijom aluminijuma sa različitim kompozitnim materijalima - karbonska vlakna/epoksi smola, staklena vlakna/epoksi smola, aramidna vlaka/epoksi smola.
