Methods of preparing polymeric gradient composites

Purpose: The goal of this work is to introduce basic methods of preparing polymeric gradient materials, which allow to join two different components to ensure the required properties and structure of the functionally gradient materials. Design/methodology/approach: In this paper few of methods of preparing functionally gradient polymeric materials are briefly described which were successful employed in many investigations performed during last few years. Findings: It was noticed that the knowledge about polymeric gradient materials is still developing what can allow to manufacture new products characterized by unique properties. Research limitations/implications: Most of methods presented in this paper are also used for conventional products, the difference between conventional products and products with gradient are quantity of components, shape and size of reinforcements, and properties of ready materials. Practical implications: Presented methods can be applied in preparing FGMs for future research programmes and also in industrial processes. Originality/value: Techniques are presented that can be useful in future scientific work concerning functionally gradient materials containing polymer materials.
