Özet

HDPE is a newly used thermoplastic for additive manufacturing but there is some problem to overcome. They need to be strengthened with various micro size additives. The distribution of the fibers in the matrix is of vital importance. The production process is affected by many parameters such as temperature, extrusion speed, cooling rate, matrix, and fiber particle size. In this study, a comparison was made by using single and twin-screw extruders to produce 10% glass and carbon and reinforced HDPE filaments. Mechanical properties were evaluated based on tensile tests. Reinforcing fiber to the HDPE matrix increases the tensile strength. If the matrix and fiber particle size are reduced to 250µ before the extrusion, it is possible to achieve high tensile results close to twin screw extrusion with single screw extrusion, but homogeneous distribution of fibers in the matrix is not satisfactory.
