Abstract

Appearance of molecular composites is grounded on fast development of rigid chain polymers and high-performance fibers on their base in United States and Russia. Brief historical review of rigid-chain polymers, fibers, and molecular composites on their base presented. Analysis of existing molecular composites and novel ways for development of these materials are in focus of the work. Properties of composite fibers and plastics containing poly-n-phenylenterehptalamide and polyamide PA-6 are shown. Blends of polysulfone with polyamidbenzamidazolterephtalamide for creation of molecular composites are discussed. Influence of shear flow rate on phase separation in the process of formation of fibrils from rigid-chain polymer inside matrix of flexible-chain polymer is demonstrated. By changing ratio between components and altering composite fibers spinning conditions, it is possible to obtain various materials – from fusible reinforced thermoplastics to heat resistant and high-strength plastics.
