Effect of Nano-Filler Aluminum Oxide and Graphene on Flammability Properties of Kenaf Epoxy Composites
https://orcid.org/http://orcid.org/0000-0002-3774-7672
This paper aims to study the flame properties of polymer reinforced composites, with the effect of nano-aluminum oxide and nano-graphene as primary and secondary fillers of kenaf natural fiber epoxy composites. Kenaf hybrid composite was prepared using the vaccum bagging technique, which avoids the voids and blow holes in the composites. Pure kenaf epoxy and varying the combination of kenaf 50–60%, nano-aluminum oxide 0–6%, and graphene 0–3% with a matrix weight ratio of 40% of epoxy resin are observed. Vertical (UL-94V) and horizontal (UL-94HB) flame tests were conducted as per the UL standards. Natural fiber composites are highly flammable, to reduce this fillers are blended. Loss of length, mass loss, and burning rate of composites were calculated from horizontal burning test. Rating of all composition samples was found out from the vertical test. An increase in nano-graphene content up to 3% flame propagation ceased before the mark, which leads to zero burning rate as nano-graphene acts as a flame retardant in composites. Increasing nano-aluminum oxide filler decreases the burning rate. Six percent nano-aluminum oxide and 3% nano-graphene fall under the V-2 rating in the UL-94 test. The specimens with 1 and 3% nano-graphene and specimens 3% nano-graphene and 6% nano-aluminum oxide result in zero percent loss of length and mass loss. Flame retardancy defines to be one of the most important properties of safety required for property of materials used in transport, military, aerospace, and construction. So these composites have greater potential to be used in building materials applications.
