“…ABS is a rubber toughened thermoplastic characterized by notch insensitivity with limitation of low thermal stability while PC has high thermal stability and good impact strength and difficult to process due to high melt viscosity. On the other hand, PC-ABS thermoplastic blends provide good mechanical behaviour when subjected to dynamic loading conditions as it combines the heat and impact resistance of PC and good processability of ABS [3]. PC-ABS was developed by Borg-warner in 1963 with the brand name, cycoloy800, further in 1995, General Electric developed a material with good heat resistance and impact resistance, without the need for paint and suited for dashboard and steering wheel cover of automobiles [4].…”

Additive manufacturing (AM) process builds the parts, layer by layer precisely from Computer-Aided Design (CAD) models, whereas traditional subtractive manufacturing process removes layers from materials to attain the desired shape. Of late Rapid prototyped (RP) parts are used for the direct production of components for manufacturing and testing in the industries. Understanding material, machine used along with the process variables that affect the strength of the final part gains importance as the parts can be printed directly from CAD data and effectively integrated into structures. The main aim of this investigation is to present the mechanical characterization and free vibration analysis of various 3D printed Engineering Plastic Materials. Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), and Polycarbonate-Acrylonitrile Butadiene Styrene (PC-ABS) materials are used in this study. Spools are prepared from plastic pellets using wire extruder. Tensile tests have been performed on dog bone specimens to evaluate strength, fractured specimen's surfaces which are further evaluated using Field Emission Scanning Electron Microscope (FESEM) to explore fracture of the raster and bonding between layers. From the experimental results it's noticed that the PC-ABS material exhibits improved elastic limit and load-carrying capacity compared with ABS and PC. Three types of beams are fabricated using different materials and modal analysis has been conducted to predict the stiffness of beams in terms of natural frequencies under clamped free (CF) and clamped clamped (CC) end conditions. Higher natural frequencies observed with PC-ABS is compared with the rest of the materials.

“…1−8 Maleated compatibilizing agents are very commonly used in polyolefin systems for improving miscibility in multipolymer blends, as well as for promoting adhesion to dispersed filler materials. 9 In PA6/PP blends, this reactive compatibilization scheme yields a PP- g -PA6 graft copolymer via a reaction in the melt state between terminal diamine groups of the PA6 with anhydride groups in PP- g -MA. 10 Although the incorporation of PP into PA6 can improve its moisture resistance and reduce the overall cost, this comes at the expense of reduced strength and stiffness.…”

Novel Compatibilized Nylon-Based Ternary Blends with Polypropylene and Poly(lactic acid): Fractionated Crystallization Phenomena and Mechanical Performance

This paper presents an investigation into the behavior and performance of blends of Nylon 6 (PA6), polypropylene (PP), and poly(lactic acid) (PLA), compatibilized with maleic anhydride-grafted PP (PP- g -MA). The mechanical performance of ternary PA6/PP/PLA blends was superior to that of binary PA6/PP blends because of the addition of PLA. Through blending with PLA, the tensile and flexural strength and modulus were enhanced, maintaining performance similar to that of neat PA6. Tensile performance was further enhanced through reactive compatibilization of the blends with PP- g -MA due to the improved homogeneity of the materials. Impact behavior of the blends was found to be highly dependent on morphology, and the toughening behavior was observed at certain blending ratios. In PA6/PP blends, fractionated crystallization behavior was investigated through differential scanning calorimetry, in which both PA6 and PP droplets were crystallized at supercooled states. This effect was highly influenced by the presence of the compatibilizing agent and its effect on the morphology of the dispersed phase. As the droplet size of the dispersed phase was decreased to submicron levels, the efficiency of heterogeneous nucleation was limited. Crystallization of PLA in the blend was poor, but PP- g -MA was found to have an impact on its rate of crystallization.

“…In any case, a typical consequence of the incompatibility can be observed on ductility, which is strongly reduced; this occurs since the poor adhesion between the two phases constitutes a defect, which can therefore propagate in presence of mechanical stresses and lead to premature breaking of the sample. This makes compatibilization necessary in order to achieve adequate properties [2,3,4,5,6,7,8,9].…”

“Compatibilization” through Elongational Flow Processing of LDPE/PA6 Blends

et al. 2018

Polyamide/polyolefin blends have gained attention from the academia and the industry for several years. However, in order to optimize their properties, some drawbacks such as chemical incompatibility must be adequately overcome. This can be done by adding suitable compatibilizers. On the other hand, it is less known that suitable processing techniques may also lead to significant results. In a previous work on a low-density polyethylene/polyamide 6 (LDPE/PA6) blend, we found that the orientation due to elongational flow processing conditions could lead to an unexpected brittle–ductile transition. In this work, this phenomenon was further investigated and the attention was mainly focused on the effects that processing can have on the morphology and, as a consequence, on the final properties of a polymer blends. With regard to LDPE/PA6 blend, an important result was found, i.e., the effects on the ductility induced by the elongational flow orientation are similar to those obtained by using an ethylene-glycidyl methacrylate compatibilizer.
