Bu çalışmada, kabak lifi takviyeli bitkisel kompozit malzemelerin yüzey topografyasının basılabilirliğine

etkisi incelenmiştir. Bu amaçla, takviye olarak kabak lifi ve matris olarak epoksi kullanılarak biyokompozit

plakalar üretilmiştir. Daha sonra bu plakaların yüzeylerine çizgi ve nokta gibi baskılar serigrafi

baskı yöntemi ile gerçekleştirilmiştir. Baskıdan önce ve sonra, üretilen biyo-kompozitlerin yüzey

pürüzlülük değerleri, 3D temassız optik profilometre kullanılarak ölçülmüştür. Daha sonra bu ölçümleri

doğrulamak ve baskı kalitesini kontrol etmek için 3D Optik Profilometre biyo-kompozit malzemelerin

yüzey pürüzlülüğünü taramak için kullanılmıştır. Elde edilen sonuçlara göre, kompozit yüzey

topografyasındaki gelişme, yüzey pürüzsüzlüğünü arttırmaktadır. Bu sonuç ile yüzey pürüzsüzlüğünün,

elde edilen görüntü netliği için basılabilirliğin ana parametresi olduğu açıkça anlaşılmaktadır.

How Does the Surface Topography of a Green Composite Affect its Printability?

Öz

In this study, printability properties of plant fiber-reinforced green composite materials were examined to understand the effect of surface topography. Since green composites are environmentally friendly materials, the main purpose of this study is to investigate and find new application areas. For this purpose, bio-composite plates using luffa fiber as reinforcement and epoxy as the matrix was produced. Then, the surfaces of these plates were carried out by the screen printing method. Before and after printing, the surface roughness values of the produced bio-composites were measured using 3D non-contact optical profilometer. Then, 3D Optical Profilometer is used to scan the surface roughness of bio-composite materials. The EPI 20X v35 lens was used to profile the surface of bio-composite materials. According to the obtained results, it has been found that the improvement of the composite surface topography increased surface smoothness, which is the most important characteristic of printability for obtained images sharpness.
