Abstract

Automobilska industrija jedna je od najvažnijih grana industrije u svijetu, a potreba za zamjenom konvencionalnih metalnih materijala sve je veća zbog nametnutih visokih zahtjeva koje proizvođači moraju zadovoljiti. Najvažniji zahtjev je smanjenje emisije štetnih plinova koji se postiže upotrebom manje količine energije potrebne za vožnju. Manja masa vozila znači i manju potrošnju energije. Pravilnim odabirom materijala, a koji će ujedno zadovoljiti svojim mehaničkim svojstvima te otpornošću na koroziju i atmosferilije, može se značajno smanjiti ukupna masa vozila. Dobar odabir su polimerni kompoziti, materijal koji zadovoljava sve kriterije i ima mogućnost projektiranja svojstva.
U ovom završnom radu prikazan je jedan od postupaka izrade kompozitnih automobilskih dijelova, a u te svrhe izrađen je krovni spojler postupkom ručnog laminiranja. U kompozitu od kojeg je spojler izrađen korišteno je ojačanje staklenim vlaknima, a materijal matrice je poliesterska smola. Opisan je postupak izrade od prototipa, kalupa do gotovog proizvoda kao i korišteni materijali.

Abstract (english)

The automotive industry is one of the largest industry branches in the world. Comparatively, the urgency for the replacement of conventional materials is also growing ever-larger, as the car manufacturers have to meet the strict and levied demands. The most important demand is the reduction of the exhaust of harmful gasses, which is achieved by lowering the power consumption needed to drive the vehicle. By appropriately choosing materials which simultaneously meet the required mechanical standards and offer resistance to corrosion and weather effects, the manufacturers can significantly lower the total mass of the vehicle. Such materials include polymer composites, which meet all standards and are customizable.
This Bachelor thesis presents one of the processes of composite automotive part production. A roof spoiler was manually laminated and constructed for the thesis purpose. The composite used in the construction of the spoiler was reinforced with glass fibres and the material used for the matrix was polyester resin. In addition to this, the manufacturing process from the prototype, to the mould and up until the finished product, as well as the materials used are presented.
