Fiber degradation
Material data - Fiber filler
The fiber filler must be defined in order to calculate the fiber degradation in REX/PSI. To do this, the Define fibers checkbox must be selected in the Fiber filler dialogue of the material. The following entries are required:
- Fibre type: Name of the fibre
- Initial fiber length
- Fiber diameter
- Fiber weight content
- Fiber density
- Young's modulus
- Elongation at break
By selecting the checkbox E-glass (standard fiber material), the fields Fiber type, Fiber density, Young's modulus and Elongation at break are automatically filled with default values.
The initial fiber length is only used for the Fiber degradation model, but not for the Fiber length distribution model.
The initial fiber length for the fiber length distribution model is defined in a separate dialogue. This can be done using a normal distribution, a value list or a predefined length.
The solid density of the matrix material must also be specified.
