Abstract

U ovom radu istraživan je utjecaj različitih tretmana površine tkanih staklenih vlakana na mehanička svojstva polimernih kompozitnih materijala, s matricom od poli (metil-metakrilat)-a koji se koristi za izradu baze proteze. Prije silanizacije staklenih vlakana provedena je aktivacija površine pomoću vodenih otopina klorovodične kiseline, HCl, i amonijevog, hidroksida, NH4OH. Površina stakla karakterizirana je FTIR spektroskopijom. Mehanička svojstva uzoraka procijenjena su pomoću vlačnog pokusa, ispitivanja udarnog rada loma i savijanja u tri točke. Preostala reaktivnost uzoraka analizirana je pomoću diferencijalne pretražne kalorimetrije (DSC).

Abstract (english)

In this work, effects of different surface treatments of woven glass fibers, on mechanical properties of PMMA matrix composite materials, used for denture base applications, have been studied. Before the silanization of glass fabric activation pretreatments were performed, using HCl and NH4OH aqueous solutions.
To characterize glass surface FTIR spectroscopy was used. Mechanical properties of composite specimens were evaluated by means of tensile, impact, and three-point-bending tests.
The residual reactivity of the samples were analyzed using differential scanning calorimetry.
