Artykuł opisuje funkcjonalne polimerowe materiały gradientowe podstawowe techniki ich wytwarzania oraz wyniki badań wybranych charakterystyk fizycznych. W badaniach wykorzystano stop Wood’a oraz żywicę epoksydową (Epidian 6) sieciowaną trietylenotetraaminą (utwardzacz Z1). Wykonane kompozyty zawierały nominalnie 20, 40, 60 i 80 % stopu Wood’a. Próbki wykonano metodą odlewania grawitacyjnego w formach umożliwiających sedymentację składników kompozytu. Następnie przedstawiono wyniki badań wytrzymałości warstw o różnej zawartości procentowej napełniacza.

The article describes the functional polymeric graded materials and their basic manufacturing techniques and the results of selected physical characteristics. In the research Wood’s alloy and epoxy resin (Epidian 6) cured with triethylenetetraamine (Z1 hardener) were used. Composites were made with nominally 20, 40, 60 and 80% by weight contents of the Wood’s alloy. The samples were made using gravity casting to the forms which allow to sedimentation of the components of composite. Next results of strength of the layers with different percentages of filler are presented.

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.
