Abstract :
Composites are one of the most commonly used materials in
aircraft. One of the weaknesses of composites is against heat resistance,
so it is dangerous to the resistance of aircraft construction. In this study,
the author tries to conduct research on the characteristics of glass fiber
composite material that has resistance to fire with the addition of fly ash.
The process of making composites using the hand lay up method.
The rainforcement used is glass fiber and the matrix uses epoxy resin and
fly ash. Manufacturing and testing are in accordance with ASTM - D635
with specimen dimensions of 125mm x 13mm x 3 mm. The specimens have
variations in the matrix, namely the addition of 0%, 10%, 20% and 30%
fly ash with 3 specimens per variation each. The test results will produce
the calculation of Time to Ignnition (TTI) and Burning Rate (BR).
The specimens were then burned according to ASTM - D635. The
results obtained were that the 30% specimen had the best heat resistance
with a TTI of 19 seconds and BR showed that the specimen died before
reaching 100 mm.
