Analysis of the Impact of 3D Printed Fiber Arrangement on Continuous Fiber Composites
Continuous fiber reinforced thermoplastic composites(CFRTPCs)3D printing technology can shorten the develop-ment cycle and increase the production efficiency of CFRTPCs parts.In order to investigate the effects of different fiber arrange-ments on the tensile properties of CFRTPCs 3D printed samples,three types of CFRTPCs tensile samples with different reinforce-ment layer distributions and six types of tensile samples with different fiber lay-up angles within the layers are designed,and the tensile damage failure process of the samples is experimented and simulated.The experimental results show that the stiffness and ul-timate tensile strength of the specimens increase with increasing fiber volume fraction,and the modulus of elasticity of the speci-mens decreases sharply when the angle between the load direction and the fiber arrangement increases.In the design of continuous fi-ber composites,it is necessary to increase the fiber content and reduce the angle between the fiber and the load to improve the per-formance.
