“…The strength of treated NaOH filament is lower by 14.11% (22.03 MPa) than r-PP at 25.67 MPa, which is similar to fidnings by Ferede et al [ 62 ] when they studied the properties of wood dust/PP composite. They stated that this decreasing strength of NaOH treated fiber composite is possibly due to aggregation of the wood dust or insufficient hydrogen bonding between the r-PP and the wood fibre.…”

The efficacy of wood dust fibre treatment on the property of wood dust reinforced recycled polypropylene composite (r-WoPPC) filament was investigated. The wood dust fibre was treated using alkali, silane, and NaOH-silane. The treated wood fibre was incorporated with r-PP using a twin-screw extruder to produce filament. The silane treatment on wood dust fibre enhances interfacial bonding between wood fibre and recycled PP; hence, a filament has the highest wire pull strength, which is 35.2% higher compared to untreated and alkaline-treated wood dust filament. It is because silanol in silane forms a siloxane bond that acts as a coupling agent that improves interfacial bonding between wood dust fibre and recycled PP. The SEM micrograph of the fracture structure reveals that treated silane has strong interfacial bonding between wood dust fibre and recycled PP, having minimal void, gap, and good fibre adhesion. The water absorption test results indicate that filament with treated wood dust absorbs less water than filament with untreated wood because the treatment minimizes the gap between wood fibres and recycled PP. The FTIR analysis identified the presence of silane on the wood dust surface for silane-treated wood dust. The DSC studies suggest that the temperature range 167–170 °C be used in the extrusion machine to produce r- WoPPC filament. As a result, r-WoPPc filaments containing silane-treated wood dust have better mechanical properties and have a greater potential for usage in FDM applications.

“…The maximum strength was achieved at 15 wt.% with a value of 89.8 MPa which is 10% higher than the matrix material. These findings are in good agreement with those obtained by other researchers [6,13]. The increase in mechanical properties may be attributed to the reduced porosity and improved spread of the resin, which results in strong interfacial bonding between the reinforcement and the resin matrix.…”

“…The compression moulding method was used for producing the particulate polymer composites with weight percentage of 0%, 5%, 10%, 15% and 20% under varying compression loads of 5 kN, 10 kN, 15 kN and 20 kN with 20 minutes curing time for all loads [2]. The composition of epoxy resin, hardener and bone powder mixture will play a critical role in determining the properties of the final composite material [6]. To ensure consistency between different samples, it is important to carefully ICFMET-2023 Journal of Physics: Conference Series 2604 (2023) 012004…”

“…The polymer polypropylene composite reinforced with and fish bone powder and egg shell was the subject of research by Isaac et al [5] and found improvement of hardness, tensile, flexural and impact strength and specific gravity with higher content of filler material and decreasing its particle size. Evasu Ferede et al [6] investigated the effect of saw dust as reinforcement in polypropylene composites produced by compression moulding with amounts ranging from 10% to 50% and reported an improvement of around 40% in tensile, compression, impact and flexural strengths. Further noticed that increased water absorption rate with an increase of wood saw dust content due to hydrophilic character of saw dust particles.…”

This study investigates the mechanical properties of epoxy based composite material reinforced with natural filler of animal bone powder. The polymer composites were prepared using compression molding process. The plates of 6 mm thickness were prepared with varying amount of reinforcement from 0%, 5%, 10%, 15% and 20% by weight at varying compression loads at constant cure time. The mechanical properties such as tensile, flexural and impact strength, water absorption of composites were evaluated as per ASTM standards. The microstructural evaluations of samples were done using scanning electron microscope. It was found that the mechanical properties of epoxy composite materials reinforced with animal bone powder were significantly improved. The polymer composite of 15 wt.% bone powder reinforcement exhibited higher strength but possesses lower ductility. The scanning electron microscope analysis showed that particles were distributed uniformly in the matrix material.

The development of the teak wood processing industry is growing rapidly, especially in the Aceh area. Allows a lot of waste to be generated. This research was conducted by utilizing sawn wood waste into particle boards. To test the physical and mechanical properties of particleboard using a matrix of teak waste and SHCP 2668 WNC resin with a ratio of 60: 40, and variations in treatment (NaOH) 2,5, 5, and 7,5% in immersion for 2 hours. Then the particleboard is compressed using a hot press machine at a temperature of 150˚C for 20 minutes, and a pressure of 50 kg/cm2. Then tested according to SNI 03-2105-2006 standards, namely density, thickness expansion, moisture content, elasticity, and modulus of fracture. The results of the particle board test on the physical and mechanical properties test, namely the density yielded the best value for the 5% (NaOH) treatment with a value of 0.854 gr/cm3, the best water content test with 2.5% (NaOH) treatment with a value of 4.563 %, viscous development with treatment (NaOH) 5% with a value of 7.573%, the best elasticity test on treatment (NaOH) 2.5% with a value of 2.470 kgf/cm2, and the best fracture modulus test on treatment (NaOH) 7.5% with a value of 48.611 kgf/cm2 declared to meet the standard requirements of SNI 03-2105-2006. With alkaline treatment, particleboard gives a relatively good value compared to no treatment.
