Fiber Orientation Analysis Services in injection-molded composites, the fiber orientation distributions show a layered nature, and are affected by the filling speed, the processing conditions and material behavior, plus the fiber aspect ratio and concentration. Without proper consideration of the fiber behavior, there is a tendency to significantly overestimate the orientation levels. The Moldflow fiber orientation model allows significantly improved orientation prediction accuracy over a range of materials and fiber contents.
A Fiber-orientation analysis can assist in:
Predict fiber orientation and thermo-mechanical property distributions in the molded part.
Predict elastic modulus and average modulus in the flow and transverse-flow directions
Calculate Poisson’;s Ratio, a measure of the transverse contraction of a part compared to its length when exposed to tensile stress.
Optimize filling pattern and fiber orientation to reduce shrinkage variations and part warpage.
Increase part strength by inducing fiber orientation along load bearing part surfaces.
