Effect of Short Glass Fiber Addition on Flexural and Impact Behavior of 3D Printed Polymer Composites

Abstract

Fused deposition modeling (FDM), one of the most widely used additive manufacturing (AM) processes, is used for fabrication of 3D models from computer-aided design data using various materials for a wide scope of applications. The principle of FDM or, in general, AM plays an important role in minimizing the ill effects of manufacturing on the environment. Among the various available reinforcements, short glass fiber (SGF), one of the strong reinforcement materials available, is used as a reinforcement in the acrylonitrile butadiene styrene (ABS) matrix. At the outset, very limited research has been carried out till date in the analysis of the impact and flexural strength of the SGF-reinforced ABS polymer composite developed by the FDM process. In this regard, the present research investigates the impact and flexural strength of SGF–ABS polymer composites by the addition of 15 and 30 wt % SGF to ABS. The tests were conducted as per ASTM standards. Increments in flexural and impact properties were observed with the addition of SGF to ABS. The increment of 42% in impact strength was noted for the addition of 15 wt % SGF and 54% increase with the addition of 30 wt % SGF. On similar lines, flexural properties also showed improved values of 44 and 59% for the addition of 15 and 30 wt % SGF to ABS. SGF addition greatly enhanced the properties of flexural and impact strength and has paved the path for the exploration of varied values of reinforcement into the matrix.

Flexural, impact, and dynamic mechanical analysis of glass fiber/ABS and glass fiber/carbon fiber/ABS composites

“…In terms of competitive results or superiorities, it can be noted that the flexural properties of GF/ABS composites reported in the present work (64.46 and 3549.71 MPa) were higher than the maximum flexural properties reported in Reference [38] for CF/ABS composites at any nozzle temperature. This suggested that the GF/ABS composites might provide competitive results or superiorities in terms of flexural properties compared with CF/ABS composites processed under similar conditions.…”

Salicylidene‐based homoleptic metal(II) complexes: Theoretical, in silico molecular modeling and in vitro cytotoxicity studies

“…The effective Schiff base condensation reaction with the formation of ligands was supported by the disappearance of the υ(-NH 2 ) stretching vibration of ophenylenediamine (3383-3364 cm À1 ) and υ(C=O) of salicylaldehyde (1725 cm À1 ) and the appearance of new peak at 1660-1677 cm À1 owing to υ(C=N) azomethine group. This band was further shifted to the lower frequency (1548-1654 cm À1 ) in the case of the metal(II) complexes (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), which indicates the involvement of azomethine nitrogen in coordination with the metal ions. 23 The ligands (HL [1][2][3][4] ) showed a broad band at 3379-3390 cm À1 due to the phenolic υ(O-H) stretching, which was absent in the spectra of complexes, indicating the deprotonation of phenolic (O-H) group and formation of a bond between phenolic-oxygen and metal ion.…”

“…Thus, FMOs provide significant information to understand drug metabolism and a large number of drugs are metabolized by oxidation and reduction reactions. The orbital energy diagram for ligands (HL 1À4 ) and complexes (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) are shown in Figures 3 and S14 The biological activity of the molecules may be influenced by the smaller energy gap value and easy charge transfer in the complexes. The complexes 2, 6, and 10 exhibit high biological activity due to the presence of an electron-donating methoxy group that might be entered into the conjugation, leading to a small energy gap and easy intramolecular charge transfer (ICT).…”

“…To support experimental results, the interaction of synthesized drug molecules (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12) with two receptor molecules, fibroblast growth factors (FGFs) and phosphoinositide 3-kinase gamma (PI3Kγ) receptors were analyzed by Autodock tools. The fibroblast growth factors (FGFs) regulate postnatal bone formation through activation of FGF receptors (FGFRs) and downstream signaling events.…”
