Abstract
Boron–modified phenolic resin (BPR) has a good thermal property, but it has deficiencies in mechanical performance. To obtain PR materials with good thermal property, graphene oxide (GO) was added along with BPR to form a GO–boron-modified PR (GO-BPR). In this study, BPR and GO-BPR were prepared and their thermal resistance and mechanical properties were investigated. In addition, the effects of GO content on the thermal resistance of GO-BPR were studied. Results demonstrate that the optimal GO content was 0.5%. The thermal properties of GO-BPR with 0.5% GO improved 1.06 times when compared with that of BPR, and the peak degradation temperature of GO-BPR increased by approximately 10°C. When compared with BPR composite, the bending, tensile, and impact strengths of the GO-BPR composite materials with 0.5% GO-BPR increased by 46, 38, and 53%, respectively.
