“…Mixing was performed manually by preparing the container, seeking to ensure the best mixing of the polymer matrix and filler. This method was used because it is practical and fast, and is economical because it does not add another process, such as extrusion, in order to mix the polymer and filler [15] . For the production of samples according to the ASTMD 638-2010 standard, an injection moulding machine (300/1400/390 CL, Krauss Maffei, Germany) was used.…”

Solid residues from agroindustry often accumulate and cause environmental imbalance. An alternative to this is to use this residue as a reinforcement in polymers. The achievement of this work was to characterize a composite with a polystyrene matrix reinforced with Brazil nut shells residues. The residues were cleaned and ground to then produce the samples via injection molding with the proportions of 0%, 2.5% and 5% of load. The specimens were characterized using mechanical tensile testing and thermogravimetric analysis (TGA). The mechanical test showed that the composite with 2.5% of filler had greater stiffness and strength was improved by 5%. Thermal analysis showed an increase in the temperature for the beginning of the degradation of the M2.5 composite. The results confirm a potential application in the automotive industry for the polystyrene composite reinforced with Brazil nut shells.

The use of biodegradable polymers in daily life is increasing to reduce environmental hazards. In line with this, the present study aimed to develop a fully biodegradable polymer composite that was environmentally friendly and exhibited promising mechanical and thermal properties. Bamboo powder (BP)-reinforced polycaprolactone (PCL) composites were prepared using the solvent casting method. The influence of BP content on the morphology, wettability, and mechanical and thermal properties of the neat matrix was evaluated. In addition, the degradation properties of the composites were analysed through soil burial and acidic degradation tests. It was revealed that BP contents had an evident influence on the properties of the composites. The increase in the BP content has significantly improved the tensile strength of the PCL matrix. A similar trend is observed for thermal stability. Scanning electron micrographs demonstrated uniform dispersion of the BP in the PCL matrix. The degradation tests revealed that the biocomposites with 40 wt·% of BP degraded by more than 20% within 4 weeks in the acidic degradation test and more than 5% in the soil burial degradation test. It was noticed that there was a considerable difference in the degradation between the PCL matrix and the biocomposites of PCL and BP. These results suggest that biodegradable composites could be a promising alternative material to the existing synthetic polymer composites.

“…Figure 9 shows that the e-waste composite (e-waste + S E) has a compression strength of 23.76 MPa while “pure” geopolymer (Geo poly) has a 24 compressive strength of 14.0 MPa. Wood-based plastic composite (W-P) can withstand compressive loads of up to 13.19 MPa, 25 32.01 MPa for 65% epoxy, and 35% of Lagenaria siceraria fiber (LS + 65% epoxy), 26 respectively. The e-waste + S E composite has a compressive strength of 23.760 MPa, which is 69.71% higher than the Geo poly composite, and this composite provides 80% greater compressive strength than wood-based plastic composite.…”

This study aimed to evaluate the mechanical characteristics and application of e-waste as a filler for glass fiber composites made of S and E (e-waste + S E). Metal, printed circuit boards, integrated circuits, diodes, and transistors were separated from the e-waste filler during milling. S and E glass fiber, epoxy, and filler were utilized in proportions of 10%, 10%, and 70%, respectively, on a volume basis. The hand lay-up technique was used to construct composite specimens. Scanning electron microscope analysis was used to gauge how filler loading affected the morphology of composite materials. The composite has a compressive strength of 23.760 MPa, which is 69.71% higher than the Geo poly composite. The tensile strength of this composite is withstood up to 16.078 MPa. It has 53% better tensile properties than Sunflower Husk composites with the same operating conditions. It gives a resistance up to 42 D during hardness test to withstand. It was 15.6% better than the NF30% epoxy composite specimen. The e-waste + S E composite gives a great opposite force of up to 2 kJ on the impact load test.; it was 86.9% higher than fly ash epoxy composites.
