MICROFIBRILLAR REINFORCED COMPOSITES - NEW MATERIALS FROM POLYMER BLENDS

Microfibrillar-reinforced composites (MFCs) are a fundamentally new type of polymer composites. MFCs are prepared by a novel technique comprising drawing a polymer blend, which leads to fibrillization (orientation of both components), followed by melting of one component while preserving the oriented structure of the higher melting point component (see Figure). This method is explained in detail by means of an example, and the mechanical parameters of an MFC are presented.
