N2 - The aim of this work was to investigate the influence of the formulation and the porosity on 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 to aid materials development. We found, that porosity is indeed a decisive factor influencing this type of composites. The most important parameter affecting the porosity was the number of layers used in the compaction process, reaching an optimum porosity of about 20-30% by stacking 3 to 4 layers of the fleeces. Furthermore, the use of MAH-PP as additive incorporated in the PP fibers improved the mechanical properties of the composites. The modeling of the elastic modulus was found satisfactory; however the influence of glass fiber orientation and length should be evaluated more in detail.
