Purpose: This work aimed to identify the crystalline phases which appear in polymeric matrix as well as to determine the degree of crystallinity for composites based on the matrix of polypropylene reinforced with glass fibre. Moreover, the value of Lp (large period) of supermolecular structure in lamellar polypropylene has also been determined. Design/methodology/approach: X-ray structural investigations of composites based on polypropylene matrix reinforced by glass fibre have been performed by means of X-ray diffraction (XRD) and small angle X-ray scattering (SAXS). Findings: For investigated composites the presence of several types of polymorphous polypropylene has been found. The crystalline part of the matrix for the investigated composites is composed of alpha phase which crystallizes in monoclinic lattice and beta phase which crystallizes in hexagonal system. Moreover, it has been found that amorphous phase in the investigated composites is made of strongly oriented smectic phase of polypropylene. Research limitations/implications: Continuation of the investigations by means of X-ray methods will enable an in-depth analysis and recognition of the structure of polymeric composites on the molecular and supermolecular level. Originality/value: The work identified crystalline phases of polypropylene which made up the matrix for the investigated composites and the value of large period for supermolecular lamellar structure of polypropylene.
