Abstract:
Continuous fibre reinforced polymer compo-sites are gaining attention in various industries for their ability to create complex geometries and reduce material usage through 3D printing. The previous work focused on either short or continuous fibers individually when examining the role of fiber length in stress transfer mechanisms. This study addresses the gap by investigating the integration of chopped long carbon fibers (0.1 to 1 mm) mixed with nylon as the matrix, and varying continuous fibers as rein-force¬ments to evaluate their impact on the mechani-cal, thermal, and morphological properties. The ex-peri¬ments are performed on laminates with fiber an-gles [0°, 45°, 90°, 135°], varying build plate orienta-tions [0° and 90°], and concentric reinforcement pat-terns. Results indicated that low temperatures im-proved transverse elastic modulus, strength, and in-plane shear properties, while high temperatures re-duced all mechanical characteristics. Kevlar fibre reinforced composite exhibited the highest tensile strength, High strength high temperature glass fibre reinforced com¬posite decreased by 14.66%, and flexural strength peaked at 86.22 MPa with concen-tric zero-degree fill.
