Ultrajet Diagnostics of the Functional Properties of a New Cutting Tool Design for the Recycling of Composite Materials

A new design of cutting tool for plastic recycling is proposed, and the use of a water–polymer ultrajet as a diagnostic tool for studying the functional properties of a material is considered. The experimental results demonstrate that the developed knife design has broad prospects for practical application. These results are confirmed by a comparative analysis of various diagnostic methods and strength calculations of the tool.
