Simulation on effect of flow induced fiber orientatioin on the mechanical properties of fiber reinforced composites
Nowadays, fiber reinforced plastic composites are replacing metals which are being used for many years. This is due to the fact that fiber reinforced plastics have high strength to weigh ratio, low cost compared to metals, and high resistance to corrosion. This paper aims to simulate the effect fl...

| description | Nowadays, fiber reinforced plastic composites are replacing metals which are being used for many years. This is
due to the fact that fiber reinforced plastics have high strength to weigh ratio, low cost compared to metals, and high
resistance to corrosion. This paper aims to simulate the effect flow induced fibers orientation on the tensile properties of
short glass fiber reinforced nylon composites. Dog-bone shaped tensile testing shapes were simulated using commercial
software called ANSYS. For the simulation, the concentration of the glass fiber was varied as 10%, %, 20%, and 30% by
weight. First, the orientation state of the fibers during molding were determined experimentally and it was observed that
majority of the fibers were aligned to the flow direct in near to the top and bottom mold walls whereas they aligned
perpendicular to the few direction in the core region. Structured mesh was constructed with 2623 elements and 2804 nodes.
As in input for the simulation, elastic modulus for each composite was obtained by performing tensile test experiment. The
simulation results indicated that the yield stress values increased significantly from 13.21 MPa for pure nylon to 56.65
MPa for 30% by weight glass fiber which leads to a conclusion that the higher the percentage of the glass fiber
reinforcement, the higher the tensile strength of the composite would be. Moreover, the numerical results showed a
decrement in deflection with the increments of fiber content. Hence, this study could assist in decisions regarding the
design of reinforced composite products. |
