Research into the Properties of a Composite Material for Microwave Applications Based on PTFE with Different Concentrations and Particle Sizes of Ceramic Filler

Introduction . The technology of printed circuit boards (PCBs) is widely used in modern electronic instrumentation. PCBs for the microwave frequency range are made based on foil composite materials, particular, polytetrafluoroethylene (PTFE). At moment, there no domestic production such a class materials. Information concerning foreign manufacturing technologies this field and influence filler characteristics material remains confidential. Therefore, research into properties materials applications with similar to analogues seems relevant. Aim Experimental determination dependence electrical mechanical depending concentration size titanium dioxide fraction. Materials methods PTFE Results results an experimental study parameters samples presented, namely: 10 % content ceramic powders (fraction 10, 49 126 µm); 5, 15 powder µm dioxide). Conclusion obtained demonstrate prospects using compositions as basis A correlation was established between percentage introduced material. studies demonstrated slight difference manufactured different ratio particle sizes PTFE. However, significant decrease their observed.
