  • Polymer composites for dental fillings - ScienceDirect

    The turbines manufactured from the mid 1980s until the late 1990s were mainly constructed using standard components. After that period, special components started being designed and manufactured for turbine use only. One of the best solutions is using composite materials in wind turbine. Most composites are made up of just two materials.

    Machining ISO-S materials is challenging because alloys transfer heat poorly, also known as low thermal conductivity. The heat generated in machining (~1100 degrees Celsius to 1300 degrees Celsius) is absorbed by the tool and workpiece instead of being carried away in the cut chips. Thereby, tool life suffers, and part distortion can occur.
