The effects of particles sizes (sea-shell) on polymer composite properties / Nor Azlina Che Soh

The particulate filler of sea shell properties varies for different sizes at 0.5mm and 1.0 respectively. The composites contain 10, 30 and 50 by weight percent with both particles size of seashell. The aim of this study is to compare the effects of polymer composite properties of different particles sizes. This particulate filler is non-reinforcing filler for both size gives low tensile strength and flexural strength properly. The finer particles sizes of sea shell give the better properties for water absorption because of it not absorbs water very well. But it is not become significance in fiammability test since it was easily burned. The finer the particle sizes does not give significance different in the effect of the particles sizes (seashell) on polymer composites.
