Introduction to Fiber
Fiber Reinforced Plastics (FRP) have widely acted as a major material because of their superior mechanical
properties, high strength to weight ratio, high toughness to anticorrosion, and high creep resistance. FRP also has
many versatile mechanical characteristics due to different fibers, matrixes and producing processes. The factors are
fiber type, fiber content, and the original fiber length (before molding). The mechanical properties of FRP product
depend on its fiber length and orientation. For long fiber, the fiber length will be degraded during molding. In
addition, orientation determines the fiber-induced anisotropic mechanical properties. The fiber orientation will be
along the flow direction in skin layer while being perpendicular to flow direction in the core layer. The deformation,
fracture and ultimate strength owing to external loads of FRP product are hard to predict. Consequently, designers
conservatively employ FRP's capabilities with some limitations.

Function Overview of Moldex3D Fiber Module
Moldex3D Fiber module helps in predicting the fiber orientation, part warpage and the resultant anisotropic
mechanical properties of fiber-reinforced materials. This module is designed to:
1. Calculate the fiber orientation of short and long fiber reinforced thermoplastics (FRTP)
2. Correct the anisotropic shrinkage and mechanical properties for the injection molded FRTP parts.
3. Link with Moldex3D Warp module in calculating 3D warpage of FRTP parts.
Moldex3D incorporates fiber analysis into the modules of Flow, Pack, and Warp. The effect induced by fiber
orientation in filling stage will have a large impact on warpage results.
Note that a dedicated license is required to run fiber analysis. Besides, Moldex3D Fiber supports all solid, shell, and
eDesign mesh models.
Moldex3D Fiber calculates fiber orientation by applying the Folgar-Tucker model and its modification for long fiber
reinforcement. Moldex3D Material Wizard provides appropriate material parameters to generate legitimate analysis
results. In the hierarchical structure of material grades in Moldex3D Material Wizard, the sign next to the
material grade entry indicates that fiber related parameters are included. In addition, the fiber related parameters
can be modified by the user if the material is added to the User Bank.
