Rapid evaluation on temperature index of epoxy resin based laminated sheet using thermogravimetric point slope method

摘要

The temperature index (TI) of epoxy resin based laminated sheet was studied using thermogravimetric point slope method (TPS). The main difference with standard JB/T 1544 is that a kinetic method is applied to describe the thermal gravimetric process and to calculate the activation energy. The final TI results comply with the insulation level of commercial laminated sheets under evaluation, indicating that this method can be used to study the TI of resin based laminated composites. However, its accuracy needs to be further studied.
