Abstract
U uvodnom djelu navedena je uloga kompozita, odnosno ugljičnih vlakana u ulozi ojačala u današnje vrijeme. Također, opisani su zahtjevi koje treba zadovoljavati okvir bicikla (krutost, čvrstoća) te je opisan kratak osvrt prema poglavljima. Nadalje, objašnjeni su kompoziti, vrste i oblici ojačala i matrica koje se koriste kod kompozitnih materijala. Opisana je proizvodnja ugljičnih vlakana i predimpregniranih vlakana. Prikazani su postupci proizvodnje ugljičnih okvira bicikla u maloserijskoj proizvodnji i u serijskoj proizvodnji koji se temelje na polaganju pletiva u negativ kalupa i toplinskom tretmanu u peći ili grijanoj preši. Analizirani su materijali koji se primjenjuju u proizvodnji okvira bicikla prema zadanim kriterijima gustoće materijala, lomne žilavosti, modula elastičnosti i čvrstoće s ciljem smanjenja mase. Najprikladniji materijal za izradu okvira bicikla je polimer ojačan ugljičnim vlaknima koji pokazuje najbolje vrijednosti specifične krutosti i specifične čvrstoće.
Abstract (english)
The introductory part states the role of composites, ie carbon fibers in the role of reinforcements nowadays. Also, the requirements to be met by the bicycle frame (stiffness, strength) are described and a brief overview according to the chapters is described. Furthermore, composites, types and shapes of reinforcements and matrices used in composite materials are explained. The production of carbon fibers and preimpregnated fibers is described. Methods for the production of carbon bicycle frames in small-batch production and in batch production based on the laying of prepregs in a negative mold and heat treatment in a furnace or heated press are presented. The materials used in the production of bicycle frames are analyzed according to the given criteria of material density, fracture toughness, modulus of elasticity and strength in order to reduce the mass. The most suitable material for making a bicycle frame is a polymer reinforced with carbon fibers which shows the best values of specific stiffness and specific strength.
