Abstract

U ovom radu opisani su materijali iz skupine kompozita s naglaskom na polimerne kompozite ojačane staklenim vlaknima. Visoki iznosi specifične čvrstoće te specifične krutosti čine te materijale kao dobre kandidate za zamjenu konvencionalnih materijala, tako i pri konstrukciji cjevovoda. U teorijskom dijelu opisani su kompoziti s naglaskom na polimerne kompozite i postupci proizvodnje istih. U eksperimentalnom dijelu provedena su ispitivanja prividne vlačne čvrstoće i krutost kompozitnih cijevi, određivanje masenog udjela ojačala i analiza strukture. Ispitni uzorci su imali ista ojačavala (staklena vlakna), a razlikovali su se u materijalu matrice (poliesterska matrica i vinil-esterska matrica).

Abstract (english)

This paper describes materials from the group of composites with an emphasis on glass-reinforced polymer compositions. High amounts of specific strength and specific stiffness make the materials as good candidates for conventional material replacement, as well as in the construction of pipelines. The theoretical part describes composites with emphasis on polymer compositions and processes for their production. In the experimental part, tests of tensile strength, pipe stiffness, determination of mass fraction of glass fibres and structure analysis were performed. The test samples had the same reinforcements (glass fibers) and differed in matrix material (polyester resin and vinyl ester resin).
