Abstract

Ovaj rad razrađuje temu polimera, a u užem smislu duromera i poliesterskih smola. U građevini, zbog razvoja znanosti i novih otkrića, dolazi do neprestanog uvođenja novih materijala. Polimeri su, kao takvi, moderniji materijal čija se upotreba sve više povećava. U ovom radu bit će dan njihov kratak povijesni pregled uključujući prvu upotrebu polimera i značajnija otkrića vezana za procese proizvodnje i nove materijale. Rad sadržava opisane osnovne podjele polimera, njihove nedostatke, prednosti i općenite karakteristike. Bitna podjela polimera jest prema termomehaničkom ponašanju i to na elastomere, plastomere i duromere. Detaljnije su opisani duromeri jer se najčešće koriste kao matrica u proizvodnji polimera ojačanih vlaknima s navedenim primjerima upotrebe u praksi. U sklopu ovog rada jest obavljeno ispitivanje obodne krutosti cijevi od polimera ojačanog staklenim vlaknima (GRP). Eksperiment je obavljen sukladno normi HRN EN 1228:2003 i dio je kontrole kvalitete ovog građevnog proizvoda. Opisan je postupak ispitivanja popraćen fotografijama i izračunata je prosječna vrijednost obodne krutosti koja bi trebala biti veća ili jednaka od nazivne vrijednosti za tu cijev.

Abstract (english)

The subject of this work is polymers, more specifically thermosets and polyester resins. In construction, new materials are constantly being introduced due to the development of science and new discoveries. Polymers are therefore modern materials that are being used more and more. In this paper, a brief historical overview of the first use of polymers and important discoveries related to production processes and new materials is given. The work includes the basic types of polymers, their disadvantages, advantages and general properties. An important subdivision of polymers is made according to their thermomechanical behaviour, namely elastomers, thermoplastics and thermosets. Thermosets are described in more detail as they are most commonly used as a matrix in the manufacture of fibre-reinforced polymers, with examples of their use in practise. As part of this work, a ring stiffness test was carried out on a glass fibre reinforced polymer (GRP) pipe. The experiment was carried out in accordance with the standard HRN EN 1228:2003 and is part of the quality control of this construction product. The test procedure is described and accompanied by photographs. The average value of the ring stiffness is calculated and should be greater than or equal to the nominal value for this pipe.
