摘要：
In this research, hybridized polyethylene (PE) composites were made from hemp and lignin. Hemp (H) was employed in concentrations of 0%, 15%, 25% and 35% with lignin (L) values ranging from 0% to 60% by volume. In a twin-screw compounder, the materials were mixed until they were uniform and then they were injected moulded into tension bars. The mechanical qualities were considered by means of tensile and impact testing. Synergies or a coupling impact of lignin were established by quantitative modelling of the simultaneous impacts of strengthening on composite characteristics. Excellent concordance was found between observed data and calculated values. In addition, the models performed well when used with data from the scholarly literature. The adding of lignin boosted the toughness from 15 to 25 MPa and hemp increased it further to 35 MPa. Modelling also confirmed that hemp's reinforcing effect was more potent than lignin's. The two materials' corresponding B values for tensile strength and impact resistance were 3.8 and 6.1 respectively. There was no evidence of synergy between the two reinforcements since they operated separately. The impact of components in hybrid materials can only be accurately assessed by quantitative analysis and modelling. © 2024. Carbon Magics Ltd.
