Prepreg or pre impregnated fabrics are fabrics made from various types of technical fibers (glass, aramid, natural fibers...) from different armatures, which have been impregnated with thermoplastic matrix (polyester, polyamide...).
These fabrics, once assembled in layers, create high-performance thermoplastic laminates, through a process of compression and thermoforming.

New line of prepeg fabrics made of glass and polypropylene (PP)
Our company is expanding its production capacity in the composites sector with the development of a new generation of thermoplastic fabrics and tapes, more specifically glass and polypropylene (PP) prepreg fabrics.
A glass and polypropylene (PP) “prepreg” fabric is made by combining textured glass yarn with multi-filament polypropylene. The flexibility of our textile technology allows us to customize glass and polypropylene (PP) "prepreg" fabrics starting from weaving pattern, weight and width based on the intended use and the required characteristics.
The consolidation of the layers is carried out through a compression molding process, heating the prepreg to a temperature of 200-220°C, higher than the melting point of the polypropylene (PP) matrix and applying pressure during the cooling phase (approximately 10 bars).
