- Two series of polyurethane composites were prepared using NDI- and MDI-based prepolymers and common polyol. NDI-based polyurethane is generally resistant to mechanical wear and rebound-resilient whereas MDI-based PU has cushioning and vibration damping features, and both types can be used as a matrix for load-bearing composites. The objective of this study was to compare the mechanical properties of composites containing 5% vol. of ceramic particles prepared with the use of the mentioned PU systems, and unmodified commercial materials. The effect of various ceramic particles on physical and mechanical properties was studied. The results showed that the mechanical properties changed in comparison to reference materials: E’ improved, and impact strength performed favorably in certain materials. Both the tensile strengths and the elongations at break of the composites were found to decrease with the content of ceramic particles; however, the hardness increased gradually. Since ceramic particles offer better stiffness and hardness, the selected composites could be a viable alternative to the pure commercial PUs available in the industry.
