Abstract

Kompozitni materijali su relativno nova vrsta materijala vrlo popularna zbog svojih iznimnih svojstava. Najzastupljeniji postupci proizvodnje rezultiraju izradcima koji zahtjevaju relativno malo dodatne obrade uz iznimku postupka obrade odvajanjem čestica tj. bušenje. Prilikom izrade provrta kod određenih tipova kompozita dolazi do raslojavanja (delaminacije) slojeva u kompozitu što nepovoljno utječe na mehanička i druga svojstva kompozita. U ovom završnom radu su obrađeni podaci dobiveni bušenjem provrta u polimernom kompozitu sa staklenim vlaknima te je zatim izrađena programska podrška za neuronsku mrežu koja na osnovu mjerenih značajki sila te parametara obrade klasificira stupanj delaminacije.

Abstract (english)

Composite materials are a relatively new type of material which is very popular due to their extraordinary properties. The most common procedures of manufacturing result in products that require relatively little additional machining with the exception of drilling. Delamination occurs during hole drilling in certain types of composites which negatively impacts the mechanical and other properties. Data collected during drilling of holes in polymer composites with glass fibers reinforcement was processed in this undergraduate thesis and then program support for a neural network was developed. The neural network will classify the resulting delamination from measured forces and the parameters of drilling
