“…Wood is a porous material that swells very easily compared to PLA. Results go in line with the work noted by Josef et al 40 and Nadir et al 41 Detailed examination through Scanning Electron Microscopy (SEM) (Figure 6) at a higher magnification of 250X has revealed the internal structure of the wood/ PLA composite. The SEM analysis unveiled the presence of clusters of wood particles that have aggregated in specific regions, accompanied by voids in certain areas of the composite material.…”

Nowadays, there is a rising demand for bio-composite materials driven by the increasing need for sustainable alternatives and a desire to lessen dependence on conventional materials. These bio-composites resent eco-friendly solutions to address these challenges. In line with this, the present study focuses on the bio composite material which developed from polylactic acid (PLA) and wood dust (NF). Wood dust sourced from teak wood plants was employed as fillers. PLA served as the matrix material, supplemented with the plasticizer polyethylene glycol (PEG) to enhance PLA processing. The PLA/NF filament was produced through the extrusion process, and specimens were prepared using 3D printing techniques in accordance with ASTM standards. Various properties including mechanical, physical, thermal stability, and tribological properties were examined. Morphological structures were observed using scanning electron microscopy (SEM). The test results demonstrated improvements in enhanced mechanical robustness and tribological performance of the PLA composite. The tensile strength of the PLA/wood composite was enhanced by 11%. The hardness value of the PLA/wood composite increased by 27% with the addition of wood as filler material. However, the introduction of wood as filler material led to degradation in physical properties. The water absorption test revealed a thickness change of approximately 14% for the PLA wood composite, whereas for pure PLA, it was 9%. Thermal stability tests showed that the temperature resistance of PLA improved to 250 °C with the introduction of wood fillers. Biodegradability tests indicated that PLA wood composite has the potential to address environmental concerns associated with conventional materials.

This research discusses the development of a high performance composite out of waste plastic that is ultralightweight, thermally insulated, and high impact resistant. Polycarbonate sheet and Cross-linked Polyethylene (XLPE) foam were combined to create the composite, and silicon adhesive was used to fabricate the composite. Polycarbonate sheets are high impact resistant material, high thermal insulation is provided by XLPE foam, and silicon adhesive is used because of its low thermal conductivity. The composite was fabricated using a stacking technique. The composite prototype was then evaluated by experimenting it to dry ice at a temperature of −78.6°C. Drop tests, compression tests, density measurements was carried out, and thermal analysis was carried out using thermogravimetric analysis. The sample can endure low temperatures while maintaining room temperature on the other side, according to a 24 h dry ice test, whilst a drop test demonstrated that it can withstand significant impact loads. A numerical simulation using Abaqus/Explicit was also used to validate the variations in temperature between the outside surface at −20°C and the inside surface maintained at 30°C of the composites when exposed to cold temperature. The result reveals that the hybrid composite are highly promising in terms of thermal insulation.
