Additively Manufactured Carbon Fibre PETG Composites: Effect of Print Parameters on Mechanical Properties.

This study investigates the quasi-static and viscoelastic properties of additively manufactured (AM) PETG reinforced with short carbon fibres. Samples were manufactured using different parameters in terms of the infill pattern, porosity, and annealing condition. Tensile and compressive tests were conducted to determine quasi-static properties such as Young's modulus and toughness, and dynamic mechanical analysis was used under a frequency sweep of 1-100 Hz to describe the viscoelastic behaviour of the composites.
