3D Printing of Glass and Carbon Fiber Hybrid Reinforced Composite and Experiments
A double nozzle of additive manufacturing platform for continuous glass fiber and carbon fiber hybrid reinforced thermoplastic composites was developed based on the fused deposition molding process.Specimens with different hybrid ratios fiber reinforced thermoplastic composites were prepared,and the bending mechanical properties as well as failure modes of different structural specimens were analyzed.In addition,the mechanical resistance behavior of continuous glass fiber and carbon fiber hybrid reinforced thermoplastic composites was explored.The results show that the flexural strength of glass fiber reinforced thermoplastic structure is increased by 115.99%and that of carbon fiber reinforced thermoplastic structure is increased by 198.76%compared with that of pure thermoplastic structure.The continuous glass fiber and carbon fiber reinforced composite has a negative flexural strength hybrid effect and a positive flexural modulus hybrid effect.The strain and fracture failure state of fiber hybrid reinforced composite structure can be self-sensing in real time according to the relative change rate of carbon fiber resistance.The study provides a new method for the high-quality and efficient manufacturing,and intelligence of continuous glass fiber and carbon fiber hybrid reinforced thermoplastic composites.
