Abstract

The main goal of this research is to investigate the ways in which the mechanical and physical properties of filament and filament were affected by varying loadings of maleic anhydride grafted polyethylene (MAPE). This research project involved the production of 3D printing filament using a material composed of recycled polypropylene/wood fibre (r- WoPPc) and MAPE. Additionally, the mechanical properties of a sample of 3D printer filament formed of r-WoPPc and the addition of MAPE were evaluated. After being supplied in small bits, wood fibre (WF) would go through a number of operations before being sieved to a size of 125 microns. An alkaline treatment with a solution of sodium hydroxide (NaOH) at a concentration of 6% was effective in treating wood flies. For the purpose of enhancing the tensile characteristics of WF, NaOH was utilised. At a temperature of 80 degrees Celsius and for a period of twenty-four hours, the WF was brought into the oven for treatment. For the purpose of producing a composite that is both robust and long-lasting, with particular mechanical qualities, the hot press method of mixing PP with treated WF and the addition of MAPE loading percentage was utilised. Once the composite has been allowed to cool, it will next be subjected to a crushing process in order to be transformed into pellet form. Fabrication of 3D printing filaments utilising a single extruder by inserting varying levels of MAPE loading (0%, 1%, 3%, and 5%) into a WF and PP as matrix as reinforcement in order to determine the mechanical and physical properties of the filaments as well as their surroundings, such as water absorption. To make the filament, the extrusion process will be aided by a single extruder machine, and the temperature setting parameter will be set to 180 degrees Celsius. Both the rod specimen (ASTM D790) and the dog bone specimen (ASTM D638) are being manufactured in three sets for each percentage of MAPE loading. A loading of 1% of MAPE into r-WoPPc is considered to be the best MAPE loading for the anticipated outcome of this experiment. Due to the increased wettability and plasticization of the WF, the incorporation of 1 weight percent of MAPE prior to the installation of MAPE improved the interfacial contacts between the WF and the matrix and protected the WF from having its integrity compromised during the reprocessing process. When compared to the 0wt% MAPE, the 1wt% MAPE yields a result that is significantly different. According to the percentage of MAPE loading, the increase in the result of mechanical characteristics and physical properties is referred to as the increment. On the other hand, the selection of 1 weight percent MAPE was the source of the significant result on the tests because the rise in the result from 1 weight percent MAPE to 5 weight percent is just slight. When the MAPE content was increased from 1 to 5 weight percent, there was also an increase in the number of big WFs.
