Influence of raster angle on tensile properties of FDM additively manufactured plates made from carbon reinforced PET-G material

چکیده
Tensile properties of thin plate specimens made from short carbon fiber reinforced PET-G material are experimentally evaluated for various raster angles (printing directions). In additive manufacturing (AM), angle is recognized as one the key printing parameters which strongly influences strength and stiffness final part. The relatively high average value ultimate tensile was obtained printed with 0? angle, compared to 90? - 52.2 MPa 25.4 MPa, respectively. Similarly, noticeably higher modulus elasticity 4752 1569 Scanning electron microscopy (SEM) used analysis specimens? fracture surfaces. SEM images revealed considerable volume fraction voids (porosity). ?he porosity, together weak bonding between two adjacent rasters, could be factors poor samples rasters perpendicular direction load application (90? angle).

Homogenization of material properties in additively manufactured structures
Additive manufacturing transforms material into three-dimensional parts incrementally, layer by layer or path by path. Subject to the build direction and machine resolution, an additively manufactured part deviates from its design model in terms of both geometry and mechanical performance. In particular, the material inside the fabricated part often exhibits spatially varying material distribut...

Honeycombs resemble the structure of a number of natural and biological materials such as cancellous bone, wood, and cork. Thick honeycomb could be also used for energy absorption applications. Moreover, studying the mechanical behavior of honeycombs under in-plane loading could help understanding the mechanical behavior of more complex 3D tessellated structures such as porous biomaterials. In ...
