We present a numerical study of the fused deposition modeling 3D printing process fiber-reinforced polymers by means Smoothed Particle Hydrodynamics (SPH). For this purpose, classical microstructure-based fiber suspension model coupled with constitutive for suspending polymer is implemented within an SPH framework. The chosen reviewed, together details and specificities its implementation in SPH. results several representative cases are then presented, mainly terms contours orientation...

A set of rheological equations is developed for semiconcentrated suspensions rigid fibers in a Newtonian fluid taking into account hydrodynamic and fiber-fiber interactions. The force generated by the fiber interactions modeled using linear friction coefficient proportional to relative velocity at contact point, weighted probability contacts occur. equation evolution second-order orientation tensor, containing advection diffusion terms due interactions, derived predict under flow. well known...

Shear and extensional properties of a commercial short glass fiber reinforced polypropylene were carefully investigated using rheometers novel on-line rheometer. This slit rheometer, installed on an injection molding press, has been designed to measure the steady shear viscosity, first normal stress difference, apparent viscosity polymer melts composites for high strain rates up 105 s−1 in 200 extension. Our results show that steady-state measurements rheometer are excellent agreement with...

The mechanical and thermal behavior of nonisothermal fiber-filled composites in a three-dimensional printing process is studied numerically with smoothed particle hydrodynamics method. A classical microstructure-based fiber suspension model temperature-dependent power-law viscosity microstructure constitutive implemented to system. described by second-order tensor A2 which describes the spatially averaged orientation fibers. Two benchmark cases are presented validate reliability present...

A rheological constitutive law is developed for a suspension of rigid rods in Bingham fluid volume fractions ranging up to the semiconcentrated regime. Based on cell model approach, which allows expressing shear stress particle surface, contribution derived and involves additional yield terms related an ensemble average orientation distribution rods. As first von Mises criterion used describe composite flow threshold, found be anisotropic sense that it depends rod orientation. dynamics...
