The use of basalt fibres to improve the hardened properties of concrete has increased in recent times. The incorporation of these fibres into concrete results in a change in the hardened state of concrete. However, these fibres also influence the corresponding fresh properties of concrete, specifically its workability.
In this study, Sulfur hexafluoride (SF 6) plasma treatment has been investigated to modify the hydrophobicity characteristics of fiber reinforced basalt/epoxy composites and evaluate the effect of plasma on their low velocity impact behavior.
Hydrophobic surfaces are highly desired for several applications due to their exceptional properties such as self-cleaning, anti-icing, anti-friction and others. Such surfaces can be prepared via numerous methods including plasma technology, a dry technique with low environmental impact. In this paper, the effect of a one-step sulfur …
