Composites based on HDPE, jute fiber, wood, and thermoplastic starch in tubular pultrusion die: The correlation between mechanical performance and microstructure

This paper presents an experimental study on pultrusion of tube‐shaped composites. Green tube‐shaped composites based on jute/thermoplastic starch, jute/HDPE, and jute/HDPE/wood flour were prepared. Jute fibers were impregnated in thermoplastic extrusion process, and a round prepreg was produced in a hot die. The impregnated jute fibers were entered into pultrusion die, and tube‐shaped composites were fabricated. Properties of final samples were...
