Abstract

The purpose of this paper is to fabricate and characterize the natural fibre (NF) reinforced epoxy composites containing flame retardants (FRs) and microcrystalline cellulose (MCC) in terms of flammability, thermal properties and dynamic mechanical performances.Design/methodology/approachThe FRs used in this study were ammonium polyphosphate and alumina trihydrate.FindingsThe results demonstrated that the addition of MCC particles into the flame retardant composite (control) further enhanced the self-extinguishing properties of composites, in particular, the burn length. Thermogravimetric analysis showed that the mass residue improved with every addition of MCC particles at 700 °C. For instance, the residual weight enhanced from 28.4 Wt.% to 33 Wt.% for the control and the composite with 7 Wt.% MCCs, respectively. As obtained from the dynamic mechanical analysis, the glass transition temperature of composites increased upon increasing inclusion of MCC particles. For example, this parameter was 77.1 °C and 86.8 °C for the control and composite loaded with 7 Wt.% MCC, respectively.Originality/valueThus, the combination of MCC and FR had been proved to be a promising flame retardant system for NF reinforced epoxy.
