Abstract

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 T‐beams. 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. Abstract : The influence of the printing path, the height of the ribs and the thickness of the layer on the bending strength and modulus of the printed T‐beam are mainly studied, and the bending failure behavior was analyzed accordingly. The work provided a new approach to the production of beam structures of the actual engineering application.
