“…Higher heat retention and low heat transfer from the outer atmosphere and vice versa should be maintained for greater efciency of the dryer. Tese factors leads us to the practical thinking of FRP-based composites as an alternative for conventional metal-based walls of the dryer cabinet due to their extensive property of heat transfer resistance between mediums [6,7]. In this research work, drying of ginger was undertaken to study and investigate the performance of the integrated composite cabinet with a solar fat plate collector.…”

Generally, solar dryer cabinets are made up of sheet metals that are heavy, costly, tend to rust over time, and possess the high heat rate to the outer atmosphere. In order to overcome these drawbacks, this research urges to develop a natural fiber reinforced polymer-based cabinet dryer, specially designed and fabricated for the purpose of solar drying. Nylon is used as the matrix material and Prosopis juliflora in particulate form is used as the natural fiber reinforcement. The dryer cabinet was designed at industrial scale to dry 5 kg of ginger at a single setting. This work also studies the efficiency of the polymer composite cabinet integrated with a flat plate solar collector system that is coated with copper and black chrome attached to corrugated fins in between the absorber plate and storage medium. The FRP chamber was compartmented in its interior with aluminium perforated sheets and experimentation was performed to determine the efficiency of the composite cabinet based on reduction of heat loss from the system. The performance of the coating, storage medium materials, and overall storage efficiency were also studied. The FRP cabinet resulted in a moisture level less than 8.5% within 4–7 days. Exergy studies showed 75% efficiency and energy studies gave 25.5 kJ/kg peak readings of drying efficiency for a period ranging between 11 and 12 hours. This was a 75% increment in energy efficiency. Thermal degradation of the FRP material was found to be stable up to 300°C. The overall weight of the constructed polymer cabinet was 25% lesser than the conventional systems.

“…The polymer matrix of the WPC gives it such properties as high moisture resistance, strength and wear resistance, non-slip surface of the WPC product even when wet, heat resistance and the ability to withstand extreme weather conditions, inaccessibility for insects, fungi, and putrefactive bacteria, ease of processing and installation [14][15][16][17]. The hydrophobic additives into WPC structure make it possible to operate composite products in conditions of high humidity, and flame retardants and antiseptics protect them from fire and decay to the entire depth of the product (unlike the surface treatment of most wooden products).…”

The paper is devoted to the properties of the wood-polymer composite based on polyethylene and barley straw. The effect of a mineral additive, namely shungite powder with a particle size of less than 20 microns, was studied. The developed composites were obtained on a laboratory two-rotor batch mixer. The mechanical and rheological properties of the composites (tensile strength and modulus of elasticity, water absorption, density, effective viscosity and modulus of elasticity) have been studied. It has been shown that the adding of shungite powder contributes to increase in the composites mechanical properties, in particular, the tensile strength increases. With an increase in the concentration of shungite, the viscosity of the composition melt decreases. The obtained thermoplastic materials can be used in construction and furniture production, as well as in the automotive industry.

“…Accordingly, incorporation of WF to polymer blends as reinforcing filler has been reported. 48 Although, some limitations restrict their application. The main drawback is the hydrophilic nature of cellulose due to the presence of polar hydroxyl groups ( OH), which weakens the interfacial interaction with the hydrophobic polymeric matrices.…”

Sustainable composites based on blends from polypropylene (PP) and recycled polyethylene terephthalate (RPET) and wood flour (WF) were prepared under industry‐relevant conditions by melt extrusion, followed by continuous drawing through spinnerets. Maleic anhydride grafted polypropylene (PP‐g‐MA) was employed to improve the compatibility between matrix and WF. The effects of incorporation of WF and RPET microstructure on the morphological features, rheological measurements, and mechanical properties were investigated. The drawing process converted elliptical RPET phase into highly oriented microfibrillar structure, as characterized by means of scanning electron microscopy (SEM). The highly oriented blend (HOB) represented nonterminal behavior due to the presence of physical networks and enhanced surface area of microfibers for chemical interactions. The tensile strength of neat PP increased by the addition of WF and the existence of microfibrillar RPET phase, whereas the microstructure of RPET had more pronounce effect. The tensile strength and elastic modulus of PP reinforced by WF and oriented RPET improved by 65% and 92%, respectively, demonstrating the high potential of this environmental‐friendly reinforcement method to intensify the mechanical properties of PP.
