Flame speed and residue properties of hybrid laminate jute/glass woven fabrics reinforced epoxy composite.

The aim of this research is to study the effect of hybrid jute and glass woven fabrics laminated on flame speed and residue properties. The laminate consists of three layers. The first specimen had all three layers of jute (JFRP), the second one had all three layers of glass (GFRP), the third had jute as outer layers with glass in the middle JGJFRP and the fourth one, the opposite of the third with glass as outer layers with jute in the middle GJGFRP. ASTM-D 635 standard was used for horizontal burning test. The result shown that flame speed of JGJFRP was 0.45% faster than GFRP. The flame speed difference between JGJFRP (H1) and GJGFRP (H2) is 0.17%. Weight loss of the sample show that the hybridization with natural fiber as the core (JFGRP) is lower than the glass fiber core (GJFRP). It can be concluded that hybrid laminate is positively influenced flame speed. [ABSTRACT FROM AUTHOR]
