In oil drilling operations,the brake system must frequently perform integral braking,in which the brake block rapidly converts energy into heat,resulting in a dramatic increase in its surface temperature.Therefore,the wear resistance and thermal degradation resistance of the brake block are crucial to maintain the stability and safety of the system.The study compares the wear resistance and thermal stability of two brake blocks with glass fiber and asbestos under the same formula,and finds a better brake block manufacturing method.Tests are performed at loads of 130 to 170 N and speeds of 200 r/min.The results show that although the friction coefficient and wear rate have similar growth trends,glass fiber reinforced materials show greater performance stability and longer life in high load and continuous friction environments,indicating greater potential to improve system reliability and reduce long-term maintenance costs.
