The Impact Of Carbon Fiber on the surface properties of the 3D Printed PEGT Product

Abstract

The primary focus of this work is the development of a hybrid composite material for 3D filaments. Polyethylene phthalate glycol (PETG) and (PETG/Carbon) fiber composite materials have their surface properties (surface roughness, Shore hardness, and micro hardness) tested. A ratio of 15% carbon fiber (in the form of carbon filaments) was used as the reinforcing filler. Using FDM (fused deposition modeling material) technology, the surface properties of PETG material used in 3D printed objects were enhanced. An ENDER 3D printer was used to create three PETG and PETG/Carbon fiber samples, using the printer setting 240°C temperature, 80°C build plate temperature, 55mm/s speed, 0.2mm layer height and speed fan 100mm/s. After that, an optical microscope and FT-IR technologies were used to investigate the samples. Results showed that as compared to PETG, the surface roughness of PETG/Carbon was reduced by 32.7%. This allowed carbon fiber to break doubly bonded in the PETG structure and also enhanced sample flow and adhesion. The PETG/Carbon samples had a Shore hardness D that was 2.16% lower than PETG's, but a slightly higher Micro hardness, making them more comparable to 10.4 HV than to 9.6 HV. However, the carbon fiber was reinforced and showed high compatibility with a PETG polymer matrix at the samples' buried structures, demonstrating that a 3D printer is an effective production tool for producing homogenized composite materials. According to claims, these features enhance the carbon fiber's ability to slide in PETG/Carbon samples.

Surface Quality Related to Face Milling Parameters in 3D Printed Carbon Fiber-Reinforced PETG

“…They discovered that the lowest roughness (4.2 µm) was achieved at the highest infill density and lowest layer thickness. Adding 15% carbon fiber to PETG improved its surface properties by 32.7%, reducing roughness from 6.34 to 4.01 µm, according to the study by Hadeeyah et al [24]. Some authors studied the effects of process parameters on the dimensional accuracy of FDM 3D printed samples using various materials, showing acceptable dimensional accuracy [25][26][27][28].…”

“…Similarly, Kadhum et al [40] investigated the effect of the infill density, identifying a quarter cubic pattern as the optimal choice to reduce the surface roughness. Also, the addition of carbon fibers to reinforce PETG filament was observed to improve the surface properties of FDM-printed samples, reducing the mean roughness from 6.34 to 4.01 μm [41]. Later on, Vidakis and co-workers [42] performed a more comprehensive study in which a variance analysis and a reduced quadratic regression model were applied to assess both the individual and the combined effect of six printing parameters (namely, raster deposition angle, infill density, nozzle temperature, bed temperature, printing speed, and layer thickness) on three indicators (i.e., porosity, surface roughness, and dimensional deviation).…”
