“…This density meets the density requirements for high-density particleboards, which range from 0.60 to 1.45 g/cm³. 39 The thickness ranged from 8 mm. The sisal fibre used had a density of 1.45 g/cm³ and the polyester resin had density of 1.1 g/cm³.…”

Millions of used or worn-out tyres are disposed of by many countries annually. These tyres can be put to good use when recycled. Used tyres are among the most problematic and challenging sources of solid waste, especially in landfills. Therefore, the use of waste tyres for composite materials having desired performance properties can be used as a means of disposing of the tyres. Fibrous material-reinforced composites with enhanced physical and mechanical performance and incorporating sisal fibres were produced using waste tyre material, sisal, and polyester resin. The physical and mechanical properties of hybrid composite board panels, including flexural strength, compression strength, tensile strength, and water absorption, were determined according to ASTM Standards. The rubber tyre particles used in the study had a size of 1.00 mm, and the sisal used had an average length of 6mm. A systematic experimental design was formulated and worked accordingly in the fabrication of the composite. The hybrid composite produced has adequate mechanical properties to perform as a substitute for solid wood in several applications such as tabletops, general purpose, load-bearing boards, ceiling boards, furniture, door panels and partitioning boards.

Due to the increasing accumulation of wastes around the world, the demand for sustainable products is increasing. Paper is a commonly disposed of material that can pose problems even when it is recycled. The concept of using cardboard (CB) as a material for furniture production has been around for many years, but CB furniture does not last long. This study examined the feasibility of using post-consumer recycled paper to produce paper-based boards for furniture design. Cardboard (CB) and office paper (OP) were the main post-consumer materials that were used. The CB and OP were mixed with polylactic acid (PLA) and limestone. The boards were made at a temperature of 200 °C and pressed at a pressure of 3.5 N/mm2 using a single opening hydraulic press. The physical and mechanical properties were tested according to the European standards for wood-based panels. Tests that are critical for furniture parts, such as the modulus of rupture (MOR), the modulus of elasticity (MOE), the internal bond, the screw withdrawal resistance, the thickness swelling, and the water absorption were examined. The paperboard samples exceeded some of the requirements for the general use of boards for interior fitments (including furniture) for use in dry conditions (Type P2) and for non-load bearing boards for use in humid conditions (Type P3).

“…Interestingly, pMDI-modified adhesives were also found to be suitable for manufacturing composites from particles other than wood, in the case of which the stronger adhesion is needed to meet the standardized strength requirements. Studies have shown that hybrid adhesives worked well as binding agents for the production of boards made of, e.g., rape straw [21], sunflower husks [22], pine bark [23], waste corrugated paper [24], and kraft paper [25]. The outcomes have shown that, due to the application of PF/pMDI resin, produced composites were characterized by satisfactory mechanical and physical features, which allowed them to fulfill the requirements of proper standards.…”

Due to the fact that impregnation with fire retardant usually reduces the strength of the produced particleboards, this research was carried out to investigate whether it is possible to use phenol–formaldehyde (PF) resin modified using various amounts (0%, 5%, 10%, 15%, and 20%) of polymeric 4,4′-methylene diphenyl diisocyanate (pMDI) for this purpose. The need to optimize the addition of pMDI is particularly important due to health and environmental aspects and high price. Furthermore, the curing process of hybrid resins is still not fully explained, especially in the case of small loadings. Manufactured particleboards differed in the share of impregnated particles (50% and 100%). The mixture of potassium carbonate and urea was used as the impregnating solution. Based on the outcomes of hybrid resins properties, it was found that the addition of pMDI leads to the increase in solid content, pH, and viscosity of the mixtures, to the improvement in resin reactivity determined using differential scanning calorimetry and to the decrease in thermal stability in the cured state evaluated using thermogravimetric analysis. Moreover, particleboard property results have shown that using impregnated particles (both 50% and 100%) decreased the strength of manufactured boards bonded using neat PF resin. However, the introduction of pMDI allowed us to compensate for the negative impact of fire-retardant-treated wood and it was found that the optimal loading of pMDI for the board containing 50% of impregnated particles is 5% and for board made entirely of treated wood it is 10%.
