“…This has also been reported by other authors on natural fibres [26,27]. The onset decomposition temperature (T 0 ) obtained in (Table 3) falls within the same range of OPEFB reinforced bio-based polyester composite studied by Dhandapani et al [28] which suggest that the presence of OPEFB enhances thermal stability of polymer composites. When 12%ATH and 15%APP-GAP/CB were added into the OPFC panel, it was effective in delaying the T 0 by 5.1 °C and 18.9 °C respectively, exhibiting better thermal stability over other FR formulations which recorded less compared to 0%OPFC panel.…”

In order to mitigate the start and spread of flame of combustible materials, flame retardants (FR) are incorporated during processing that influences mechanical and thermal properties. In this paper six (6) FR species derived from aluminium hydroxide (ATH), ammonium polyphosphate with gum arabic powder (APP-GAP) a new FR, ATH/APP-GAP hybrid formulation and CB synergist at 0, 12, 15 and 18% loading ratio were developed in oil palm fibre reinforced polyester composites panel using hand lay-up compression moulding technique. The effect of the FR on the mechanical, thermal and flame spread properties were then evaluated. Flame spread results using radiant panel flame spread apparatus show hybrid flame retardant panel traveled less distance of 150 mm from 450 mm of the control without FR which represents a 67% decrease and indicative of a weak available flame spread energy that led to flame extinguishment. Mechanical properties obtained with the universal testing machine reveals improved tensile strength, tensile modulus and flexural strength in the case of the 12%ATH non-hybrid FR by 16.2%, 5.9% and 71.2% respectively, indicative of ATH having great affinity with the polyester resin and effective transfer of stresses. Thermogravimeteric analysis reveals that the 12%ATH non-hybrid FR and the 15%APP-GAP/CB non-hybrid-synergist FR are more thermally stable before degradation began around 376 °C and 391 °C and fully degraded at 421 °C and 415 °C respectively. Char residue at 900 °C also confirms that the non-hybrid synergist residual mass at 17.47% indicative of a rich decomposition nature of APP-GAP-CB into a more stable char structure could be a good flame retardant. The results obtained indicates that the new concept of APP-GAP to formulate an hybridized FR and non-hybrid-synergist in oil palm fibre-polyester panel is feasible to meet the expectations of a good flame retardancy and thermal stability but do not support improved mechanical properties.

Basic research on recyclable, renewable and biodegradable polymer composite materials reinforced with natural fibers is increasingly growing. In this article, we characterize agricultural waste by determining its dielectric properties for microwave absorber application. Recently, polymer composites reinforced with natural fibers are increasingly used in dielectric and aircraft applications. We used a Thermal Hake blending machine to blend oil palm empty fruit bunch with polycaprolactone grain to make a homogeneous powder. The functional groups of the resulting composites were then analyzed through Fourier transform infrared spectrometry. Thermogravimetric and differential thermogravimetric analyses were performed to determine the thermal degradation behaviors of the composites. The tensile strength, tensile modulus and elongation at break of the composites were measured in an Instron universal testing machine. A rectangular waveguide and open‐ended coaxial probe connected to a microwave network analyzer (PNA) Agilent N5230A PNA‐L was used to measure the reflection coefficient S11 and transmission coefficient S21 values and the dielectric properties of the composite materials. Results showed that the thermal stability and dielectric properties of the polymer composites decreased as the fiber content increased. The composites exhibited potential as microwave absorbers at microwave frequencies. POLYM. COMPOS., 39:E1778–E1787, 2018. © 2018 Society of Plastics Engineers

“…Since biomass fiber has high fiber content, it has the potential to be as reinforcement in the composite. However, to utilize EFB as a reinforcing material, there is a need to improve the characteristics of the fiber [8][9]. The incompatibility between the hydrophobic polymer and the hydrophilic fiber is the main drawback in the production of biocomposite.…”

Oil palm empty fruit bunch (EFB) has a big potential in biocomposite production. The porous surface of EFB is advantageous for physical interlocking with polymer in composite fabrication. The objective of this study is to determine the properties of biocomposite prepared from steam-treated EFB with polypropylene (PP). The EFB was treated using steam at 120 °C for 30 min and 60 min in an autoclave. The biocomposite was prepared from EFB and PP at different fiber contents (10 and 30 wt.%). The Steam-30 EFB partially removed silica bodies and other impurities without damaging the surface of the EFB. The thermal stability improved from 276 to 283 °C. The Steam-30/PP biocomposite had the highest tensile strength at 10 and 30 wt.% EFB contents with the increments of 23.9 and 23.8%, respectively, compared to that of the untreated EFB/PP biocomposite. The Steam-30/PP biocomposite containing 30 wt.% of EFB had a low water absorption of 5.6% compared to that of the untreated EFB/PP biocomposite at 7.2%. In conclusion, steam treatment improved the characteristics of EFB and increased the compatibility between the fiber and polymer.
