Fiber Orientation Kinetics of a Concentrated Short Glass Fiber Suspension in Start up of Shear Flow
The common approach for simulating the evolution of fiber orientation during flow in concentrated suspensions is to use an empirically modified form of Jeffery’s equation referred to as the Folgar-Tucker model. Direct measurements of fiber orientation were performed in startup of shear flow for a 30 wt % short glass fiber-filled polybutylene terephthalate (PBT-30); a matrix that behaves similar...

The common approach for simulating the evolution of fiber orientation during flow in concentrated suspensions is to use an empirically modified form of Jeffery’s equation referred to as the Folgar-Tucker (F-T) model. Direct measurements of fiber orientation were performed in the startup of shear flow for a 30 wt % short glass fiber-filled polybutylene terephthalate (PBT-30); a matrix that behav...
متن کاملNMR study of the anisotropic transport properties of uniaxially stretched membranes for fuel cells
We used NMR techniques to probe the anisotropic properties of stretched Nafion 115 membranes. The alignment of the polymeric structure under a uniaxial load is at the origin of a strong anisotropy of both the water self-diffusion coefficient and the proton conductivity. The determination of these two important membrane properties may lead to new fundamental information on the nature of the pr...
متن کاملThe Effect of Fiber Orientation on the Toughening of Short Fiber-Reinforced Polymers
The effect of fiber orientation on the toughening of polymers by short glass fibers generally below their critical length was investigated using specimens with either well-aligned or randomly oriented fibers. The fibers were aligned by an electric field in a photopolymerizable monomer, which was polymerized while the field was still being applied. These materials were fractured with the aligned...
متن کاملEffects of Fiber Length and Fiber Orientation Distributions on the Tensile Strength of Short-fiber-reinforced Polymers
This paper presents an analytical method considering the effects of fiber length and fiber orientation distributions for predicting the tensile strength (TS) of short-fiber-reinforced polymers (SFRP). Two probability density functions are used for modelling the distributions of fiber length and fiber orientation. The strength of SFRP is derived as a functiolz of fiber length and fiber orientati...
