Predication of the in-plane mechanical properties of continuous carbon fibre reinforced 3D printed polymer composites using classical laminated-plate theory

In this study in-plane mechanical properties of continuous carbon fibre reinforced thermoplastic polyamide composite manufactured using a Markforged Two 3D printing system was evaluated and compared against predicted values from classical laminated-plate theory. Strength, stiffness Poisson’s ratio the specimens were measured tensile testing both in longitudinal transverse direction shear also measured. The influence orientation on investigated with that non-reinforced nylon samples known material property literature. It determined modulus elasticity strength significantly improved to 603.43 MPa 85 GPa respectively as compare unreinforced specimens. Furthermore, cross-sectional micrographs are analysed observe microstructure fracture mechanism printed composite. Experimentally used predict behaviour materials different theory commercially available LAP (Laminated Analysis programme) software. model developed will allow designers elastic (mechanical) parts for components which require specific properties.
