PROJECT DESCRIPTION

The use of Carbon fiber-reinforced composites (CFRCs) with thermoplastic matrices suffers from drawbacks regarding their manufacture in industrial applications. Understanding the impregnation mechanisms at the micro-scale is important to achieve a good quality of CFRCs. The prepreg used to fabricate CFRC intermediates. The fiber impregnation process by melting the polymer matrix is intrinsically heterogeneous at all length scales. A multi-scale simulation approach was proposed to predict the degree of impregnation (DoI) in thermoplastic unidirectional carbon fiber prepreg (UD-CFP). The project is carried out with the following objectives:

To develop a multi-scale CFD model to predict the (degree of impregnant) DoI of an impregnation die for the production of a thermoplastic unidirectional carbon fiber prepreg (UD-CFP).

To validate with the experimental data for the relative resin amount of the final UD-CFP tape.

BENEFITS

Multiscale CFD model can be used as a useful tool to predict DoI of the product.

The impregnation process can be optimized using multiscale CFD model.
