N2 - In this work we investigated the influence of glass fiber content, number of layers and initial length on the residual fiber length and the properties of partially compacted composites made of commingled polypropylene and glass fibers. Furthermore, we wanted to develop a model to predict the properties of such composites. We found, that despite of a significant degradation of fiber length due to the processing, increasing glass fiber content and initial fiber length leads to higher portions of longer fibers and mechanical properties are improved, but only when the porosity remains among certain levels. Porosity is therefore the critical factor influencing this type of composites. The modeling of the elastic modulus was found satisfactory for composites with porosity volume content under 0.5.
