Bending properties and failure behavior of 3D printed fiber reinforced resin T‐beam

Abstract

Fiber-reinforced resin T-beams have a wide range of applications. The forming of T-beams based on the fused deposition process provides a new method for its manufacture. This paper studied the key process parameters of 3D printing continuous fiber and short fiber reinforced resin T-beams. The results show that continuous fiber reinforced resin T-beams with similar fiber volume fractions have better bending performance than shorter fiber reinforced resin Tbeams. When the printing layer thickness is 0.7 mm, 0.8 mm and 0.9 mm, the flexural strength and modulus of the continuous fiber reinforced resin T-beam are obviously lower with the increase of the layer thickness. Under the printing path 0 , ±45 , 90 , the short fiber reinforced resin T-beam with the 0 path has the highest flexural strength and modulus. Furthermore, T-beam with different printing path have significantly different bending failure behavior. The work provided a new approach to the production of beam structures of the actual engineering application.

Design and Optimization of 3D-Printed Variable Cross-Section I-Beams Reinforced with Continuous and Short Fibers

“…With the introduction of 3D printing, the designability of CCFs has been significantly improved due to the removal of mold restrictions. Multiple types of beams with diverse shapes were fabricated using 3D printing and were subsequently evaluated by mechanical investigation [ 17 , 18 , 19 , 20 , 21 ]. Distinct infill patterns, including rhombus, square, and classic hexagonal, were utilized to manufacture 3D-printed cellular-cored sandwich beams made of CCF composite materials [ 17 ].…”

Influence of 3D printing technological parameter number of shells on selected mechanical properties in FDM/FFF technology

“…Belonging to Industry 4.0, additive technologies offer the possibility to set values for a large variety of technological parameters of 3D printing, which have an impact on the properties of the manufactured finished product (Benamira et al, 2023;Do et al, 2022;Kadhum et al, 2023;Oleksy et al, 2019). The assessment of the effect of 3D printing parameters (print orientation 0°, 45°, 90° and layer heights of 0.6 mm, 0.7 mm, 0.8 mm) on the bending of resin and carbon fibre-reinforced T-bars presented in the publication is an example (Wu et al, 2022). The results of the tests presented that the layer thickness and direction of the print have an impact on the bending strength.…”
