                    Abstract: In this paper, the bisphenol F epoxy resin (BPFER for short) is blended with the self-made boron
                phenolic resin with its own characteristics of low viscosity and very low molecular weight to obtain a industrial
                applicable system with excellent thermal stability and low cost. The boron phenolic resin and bisphenol F epoxy resin were
                uniformly mixed at 60 ℃ according to different mass ratios, and their thermal properties were tested by thermogravimetric
                analysis (TGA). The results show that the initial thermal decomposition temperature T d  of the sample with the best
                performance of the system is 304  ℃ , the thermal degradation temperature T 50 % is 420  ℃ , and the carbon
                residue rate W 800  ℃ is 12.9%, which proves that its thermal stability and carbon residue rate are relatively good.
