A Study on Applying Short Time Molding Method Using Novolac Benzo-Oxazine Resin

Being environmentally conscious in reducing CO2 output, is driving industries to be more efficient in using resources. Industries are also finding ways to reduce energy consumption for all aspects of manufacturing. The brake lining manufacturing process relies on electric power during the thermoset cure and post-cure of Phenol Novolac resin. Unreacted resin will complete its cure process during the ‘post-cure’ phase. The electric power consumed during the molding and post-cure process is significant compared to the total power consumed for the entire lining manufacturing process. By using Novolac Benzo-oxazine resin and utilizing high temperature short cycle molding, we could reduce power consumption. The finished Phenol Novolac brake lining will have the same performance as the phenol brake lining. A substantial reduction in electric power consumption is achieved with the new process.
