“…Thus, based on the results obtained, all the samples met the standard for insulation fibreboard requirements. From this experiment, the MOR showed a significant increase when the sample density increased from 400 kg/m 3 to 427 kg/m 3 (see Figure 6), and this result is consistent with other studies using natural fibres [129]. The MOR increased with increasing board density [130,131].…”

“…The excellent compression ratio and better particle bonding within boards led to a better contact area between the resin and wastes of EFB+MF particles, which resulted in high strength properties. Conversely, the lowest MOR value referred to the sample (i.e., CH+EFB) due to the porous structure applied to the sample and the reduction in inter particles' contact area, which resulted in the formation of weaker bonds [129].…”

Malaysia, like most other developing countries, is facing an increase in the generation of waste and accompanying problems with the disposal of this waste. A large number of biomass wastes were generated due to increased activity in the agricultural and agro-industrial sectors, which led to producing environmental hazards and waste management issues. On the other situation, the energy consumption to cool the indoor building environment is high due to the building being exposed directly to solar radiation throughout the daytime, which increases the temperature outside and inside the building. Most of the low-medium cost housing schemes were constructed using metal roof covering without providing a roof insulation layer which causes a rising in indoor temperature and creates uncomfortable surroundings. Moreover, existing materials for roof insulation in the market use inorganic synthetic materials that could harm human health. The study aims to investigate the potential use of agricultural wastes for the production of roof board insulation material that can provide economic value added to agricultural waste, reduce the environmental issue and provide eco-friendly, sustainable building material. In this study, these agricultural wastes are combined in different proportions of 50% individual fibres, such as sugarcane bagasse with coconut husk, empty fruit bunch with mesocarp fibre, coconut husk with empty fruit bunch, and sugarcane bagasse with mesocarp fibre. The sample was fabricated using the hot-press machine and went through various physical and mechanical testing, which involved thickness of swelling, modulus of rupture, and thermal conductivity. The finding showed that the mixed fibre of empty fruit bunch and mesocarp fibre achieved all the criteria such as density (427 <500kg/m3); thickness of swelling (19< 20%); modulus of rupture (514<800psi), thermal conductivity (0.0856<0.25 W/m.K) met with the standard requirement in every laboratory test conducted. The outcome of this study suggests that empty fruit bunch and mesocarp fibre are the potential materials for the production of roof board thermal insulation. However, modification of physical and mechanical properties of waste fibre is required to achieve superior performance and is ready to be provided in the market. This study is aligned with the government initiative for the growth of green building materials for sustainable development in the construction industry.

“…The higher the compatibility, the more effectively the nHA can transfer stress between the PLA/PCL matrix. Therefore, nHA has a better stress concentration and can withstand higher stresses when stretched or pulled before failure [ 72 ]. The tensile strengths of the specimens 0%, 10%, 20%, and 30% were 16.75 MPa, 30.68 MPa, 27.57 MPa, and 26.07 MPa, respectively.…”

Hydroxyapatite has the closest chemical composition to human bone. Despite this, the use of nano-hydroxyapatite (nHA) to produce biocomposite scaffolds from a mixture of polylactic acid (PLA) and polycaprolactone (PCL) using cold isostatic pressing has not been studied intensively. In this study, biocomposites were created employing nHA as an osteoconductive filler and a polymeric blend of PLA and PCL as a polymer matrix for prospective usage in the medical field. Cold isostatic pressing and subsequent sintering were used to create composites with different nHA concentrations that ranged from 0 to 30 weight percent. Using physical and mechanical characterization techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and density, porosity, tensile, and flexural standard tests, it was determined how the nHA concentrations affected the biocomposite’s general properties. In this study, the presence of PLA, PCL, and nHA was well identified using FTIR, XRD, and SEM methods. The biocomposites with high nHA content showed intense bands for symmetric stretching and the asymmetric bending vibration of PO43−. The incorporation of nHA into the polymeric blend matrix resulted in a rather irregular structure and the crystallization became more difficult. The addition of nHA improved the density and tensile and flexural strength of the PLA/PCL matrix (0% nHA). However, with increasing nHA content, the PLA/PCL/nHA biocomposites became more porous. In addition, the density, flexural strength, and tensile strength of the PLA/PCL/nHA biocomposites decreased with increasing nHA concentration. The PLA/PCL/nHA biocomposites with 10% nHA had the highest mechanical properties with a density of 1.39 g/cm3, a porosity of 1.93%, a flexural strength of 55.35 MPa, and a tensile strength of 30.68 MPa.

“…From the bar graphs presented, the WA value is the highest at the hot press temperature of 160℃ and the lowest at 180℃. The increased of WA value when hot press temperature is elevated from 140℃ to 160℃ is due to uneven compactness of OPaF Composite Board and the presence of voids in between particles that allow more water uptake during immersion [13].…”

This paper focused on the effect of different hot press temperature on the microwave pre-treated oil palm fronds (OPaF) composite board. The oil palm fronds were dried and crushed into smaller particles by using a crusher machine. Sieved oil palm fronds particles that retained on the 0.60 mm sieve mesh were selected to manufacture composite boards with a targeted density of 0.8 g/cm 3. The 20 cm × 20 cm × 0.50 cm composite boards were manufactured by applying three different hot press temperatures of 140℃, 160℃ and 180℃, respectively. A pressure of 7 MPa of the hot press machine was applied for each composite board's production. The physical and mechanical performance of oil palm fronds composite boards were tested according to the Japanese Industrial Standard (JIS A5908:2003). The physical and mechanical properties of composite board showed improvement in performance as the hot press temperature being elevated. The internal bonding strength obtained were 5.06 N/mm 2 , 6.23 N/mm 2 and 5.96 N/mm 2 , respectively as the hot press temperature is elevated from 140℃ to 180℃. The results of modulus of rupture were 16.84 N/mm 2 , 18.58 N/mm 2 and 20.11 N/mm 2. The cross-section and surface morphologies of fabricated boards were characterized via scanning electron microscopy (SEM). The images of samples with hot press temperature of 180 ℃ showed flatten particle structures and more distributed glue lines compared to the other two samples.
