Abstract (EN): In the present work, a carboxylic-acid-anhydride-modified polypropylene additive was used to improve the interfacial properties of low-cost glass fiber/polypropylene (GF/PP) towpregs produced in developed dry coating equipment. The article describes how the use of the additive affects towpreg processing conditions. The towpregs were used to produce composites by compression molding and filament winding. The produced composites were submitted to mechanical testing. Improvements were clearly identified on the fiber/matrix interface by comparing the obtained results with those determined from non-added GF/PP composites.
