✦ Synopsis

In this article, the effect of adding micro glass powder into basalt fiber reinforced epoxy composites on the Charpy impact behavior is investigated by both flatwise and edgewise specimens. Also, the effect of adding micro glass powder at two temperatures is examined on the Charpy impact behavior in order to obtain a more detailed knowledge of the role of micro glass powder in polymer composites. Moreover, the effect of adding metal layers to basalt fiber reinforced epoxy composites with various combinations of metals to make basalt fiber metal laminates in Charpy impact test is studied. Finally, it was found that adding micro glass powder increased energy absorption and this effect improved by increasing temperature. Moreover, the superiority of basalt fiber metal laminates in energy absorption as compared to basalt fiber reinforced epoxy is observed. Scanning electron microscopy is used for selective specimens to analyze the nature of fracture surfaces.
