چکیده
Fused filament fabrication (FFF) has become one of the most popular, practical, and low-cost additive manufacturing techniques for fabricating geometrically complex thermoplastic polyurethane (TPU) elastomer. However, there are still some uncertainties concerning relationship between several operating parameters applied in this technique mechanical properties processed material. In research, influences extruder temperature raster orientation on FFF-processed TPU elastomer were studied. A series uniaxial tensile tests was carried out to determine strength, strain, elastic modulus that had been printed with various temperatures, i.e., 190–230 °C, angles, 0–90°. Thermal chemical characterizations also conducted support analysis research. The results showed ductile characteristics TPU, specific strength strain could reach up 39 MPa 600%, respectively. failure mechanisms result stress by using developed Mohr’s circle discussed paper. conclusion, extrusion 200 °C angle 0° be preferred FFF process achieve high

Thermal Stability and Fire Properties of Salen and Metallosalens as Fire Retardants in Thermoplastic Polyurethane (TPU)
This study deals with the synthesis and evaluation of salen based derivatives as fire retardants in thermoplastic polyurethane. Salens, hydroxysalens and their first row transition metal complexes (salen-M) were synthesized (Copper, Manganese, Nickel and Zinc). They were then incorporated in thermoplastic polyurethane (TPU) with a loading as low as 10:1 weight ratio. The thermal stability as we...
متن کاملEnhanced Coarse-Graining of Thermoplastic Polyurethane Elastomer for Multiscale Modeling
The objective of this work is to develop a multiscale modeling tool of copolymers with long chains. We propose an enhanced coarse-graining method of thermoplastic polyurethane (TPU) with three beads. The proposed coarse-graining provides an accurate molecular modeling tool to keep the molecular interaction together with computational efficiency. The coarse-grained model with three beads is furt...
متن کاملCharacterization of Thermoplastic Polyurethane (TPU) and Ag-Carbon Black TPU Nanocomposite for Potential Application in Additive Manufacturing
Electromechanical, adhesion, and viscoelastic properties of polymers and polymer nanocomposites (PNCs) are of interest for additive manufacturing (AM) and flexible electronics. Development/optimization of inks for AM is complex, expensive, and substrate/interface dependent. This study investigates properties of free standing films of a thermoplastic polyurethane (TPU) polymer and an Ag–carbon b...

Reinforcement of flexible fibre reinforced plastic (FRP) composites with standard textile fibres is a potential low cost solution to less critical loading applications. The mechanical behaviour of FRPs based on mechanically bonded nonwoven preforms composed of either low or high modulus fibres in a thermoplastic polyurethane (TPU) matrix were compared following compression moulding. Nonwoven pr...
