Abstract
U ovome radu istražena su savojna i međuslojna svojstva kompozita na bazi epoksidne smole ojačane različitim brojem slojeva biaksijalno orijentiranih lanenih vlakana. U sklopu projekta izrade ekološki prihvatljivoga katamarana PROeco, u tvrtki Marservis d.o.o., procesom vakuumske infuzije izrađeni su visokokvalitetni kompoziti s 40 % masenog udjela ojačala. Istražen je utjecaj broja slojeva vlakana na savojna i međuslojna svojstva kompozita. Dobiveni rezultati uspoređeni su sa zahtjevima Hrvatskog registra brodova (HRB) za kompozite ojačane staklenim vlaknima. Rezultati pokazuju da propisane minimalne vrijednosti savojnog modula elastičnosti zadovoljavaju svi uzorci, minimalne vrijednosti savojne čvrstoće zadovoljavaju samo uzorci s četiri i sedam slojeva vlakana, dok vrijednosti prividne međuslojne smične čvrstoće zadovoljava samo uzorak sa šest slojeva vlakana. Odstupanja od propisanih vrijednosti čvrstoće su od 0,57 do 6,85 %, a prividne međuslojne smične čvrstoće od 0,88 do 6,29 %.
Abstract (english)
In this work, the bending and interlayer properties of epoxy based composites reinforced with a different number of layers of biaxially oriented flax fibers were investigated. As part of the project for the production of environmentally friendly catamaran PROeco, in the company Marservis d.o.o., high quality composites with 40 m.% fibers were made by vacuum infusion process. The influence of the number of fiber layers on the bending and interlaminar properties of composites was investigated. The obtained results were compared with the requirements of the Croatian Register of Shipping (CRS) for glass fibers reinforced composites. The results show that the prescribed minimum values of flexural modulus of elasticity are met by all samples, minimum values of flexural strength are met only by samples with four and seven layers of fibers, while the values of apparent interlaminar shear strength are satisfied only by sample with six layers of fibers. The deviation of flexural strength is between 0,57 and 6,85 %, whereas apparent interlaminar shear strength is between 0,88 and 6,29 % lower.
