<![CDATA[The purpose of this research was to investigate the effect of layers number towardflame resistance ofripoxy R-802 EX 800 gr/m2 woven roving e glass fiber glass composite. The flame resistance characteristic studied were the ignition time and the burn rate of ripoxy R-802 EX800gr/m2 woven roving e glass fiber glass composite with the number of fiber glass layers variation (up to 5 layers).The method which used in this research was experimental method. The research was done at Engineering Materials Laboratory, Mechanical Engineering Department, Engineering Faculty, of Sebelas Maret UniversitySurakarta which located at Jalan Ir. Sutami No.36 A Surakarta. The equipment which used to study composite burning resistant was burn tester based on ASTM D-635. The specimens in this research was ripoxy R-802 EX800gr/m2 woven roving e glass fiber glass composite. Burning test was done based on ASTM D-635 standard (horizontal burning test). The data analysis which used in this research was descriptive analysis method.Based on experimental result can be concluded: (1) The effect of fiber glass layers number indicated more fiber glass layers number caused increasing of ingnition time and decreasing burn rate at composite. It was indicated that more fiber glass layers number will decreased composite burn rate. (2) 5 woven roving 800gr/m2 fiber glass layers caused this composite inflammable and the best variation of spessimen, because the fire extinguished before recommended distance based on ASTM D-635UL 94.]]>
