Shear and Tensile Behaviors of Fiber-Reinforced Resin Matrix Composites Printed by the FDM Technology

Resin/fiber composites were prepared by the FDM printing technology. The effects of arrangements, types (carbon, glass, and Kevlar), volume fraction fibers on shear tensile properties resin 3D-printed are investigated in this paper. experimental results show that addition continuous increases strength FDM-3D-printed composites, but will not keep increasing with an increase fiber content. As content increases, print quality decreases, porosity between increases. enhancement degree stress specimens different can be classified as follows: glass > carbon Kevlar fiber. Notch sensitivity is reduced when 90° arrangement added, while 0° arranged improve notch sample. research paper have important guiding significance for selecting mode notched components engineering applications.
