3D printing and mechanical properties of glass fiber/photosensitive resin composites

Aiming at the low strength of light-cured 3D printing resin materials,a method of using glass fiber to reinforce photosensitive resin composites was proposed.The glass fiber and the photosensitive resin were compounded and rapidly fabricated by using the light-cured 3D printing technology.The effects of glass fiber modification and the laying method of glass fiber on the mechanical properties of the composites were studied.The results of the mechanical experiments were analyzed,demonstrating that the glass fiber could enhance the tensile strength and flexural strength of the sample.The glass fiber treated by the silane coupling agent is more significant than the untreated glass fiber for the mechanical properties,and the tensile strength of the sample is increased by 50%,and the bending strength 143%.The effect of the laying method simulating three-dimensional orthogonal structure on mechanical properties of the composites is more significant than the continuous long fiber laying method,and the tensile strength is increased by 110%and the flexural strength 147%.
