The integration of intumescent flame-retardant (IFR) additives in natural fiber-based polymer composites enhances the fire-retardant properties, but it generally has a detrimental effect on the mechanical properties, such as tensile and flexural strengths. In this work, the feasibility of graphene as a reinforcement additive and as an effective synergist for IFR-based flax-polypropylene (PP) composites was investigated. Noticeable improvements in tensile and flexural properties were achieved with the addition of graphene nanoplatelets (GNP) in the composites. Furthermore, better char-forming ability of GNP in combination with IFR was observed, suppressing HRR curves and thus, lowering the total heat release (THR). Thermogravimetric analysis (TGA) detected a reduction in the decomposition rate due to strong interfacial bonding between GNP and PP, whereas the maximum decomposition rate was observed to occur at a higher temperature. The saturation point for the IFR additive along with GNP has also been highlighted in this study. A safe and effective method of graphene encapsulation within PP using the fume-hood set-up was achieved. Finally, the effect of flame retardant on the flax–PP composite has been simulated using Fire Dynamics Simulator.

AbstractA layered bamboo-plastic composite (BPC) consisting of bamboo (Phyllostachys makinoi) particles and polypropylene was investigated. The influence of the layering conditions, including the thickness and bamboo content in various layers, was the focus in terms of the physicomechanical and creep properties of the BPCs. The results showed that a three-layered BPC (BPC3L) with a 1:3:1 thickness ratio and with top/bottom layer containing 40% bamboo exhibited the best specific flexural properties. An accelerated creep test approach was applied, known as the short-term stepped isostress method (SSM), to predict the long-term creep behavior of BPC3L. The results indicated that the creep master curves, which are constructed from different SSM testing parameters, agree well with the long-term experimental creep data and that the creep resistance of homogeneous single-layered BPC was better than that of BPC3L.

Fuel Resistance

Has successfully created an optimum composite of rPP/DVB/PP-AA/comBen+ZB based on the mechanical and fuel resistance properties. The starting material recycled PP (rPP), PP modified acrylic acid (AA) as coupling agent (PP-AA), crosslinker divinylbenzene (DVB), 20 phr of commercial bentonite (comBen) and 5 phr of zinc borate (ZB), was reactivelly processed in xylene. Composites analysis using XRD presented that the bentonite had been exfoliated inside of PP matrix. Test results showed that both of tensile strength (TS) and young's modulus (YM) of rPP/DVB/PP-AA/comBen+ZB composites following ASTM D638 was increased. The testing results of burning rate (BR) of composite rPP/DVB/PP-AA/comBen+ZB according to ASTM D635 decreased. The presence of bentonite as a natural fire retardant and ZB as fire retardant additive on composite rPP/DVB/PP-AA/comBen+ZB able to increase mechanical properties and also improving the flammability resistance.
