摘要：Allyl ether naphthol resin (ANPF) was synthesized by introducing 1,5-dihydroxynaphthalene and 2,7-dihydroxynaphthalene into phenolic resin and was copolymerized with 4,4 '-bismaleimidodiphenylmethane resin (BDM) to obtain allyl ether naphthol-modified bismaleimide resins (15-ANPF-BDM and 27-ANPF-BDM). The resulting thermal stability and glass transition temperature (Tg) were explored by thermogravimetric and dynamic mechanical analyses. The char yield of 15-ANPF-BDM at a temperature of 800 degrees C was 46.0%. Additionally, the Tg of 15-ANPF-BDM was measured as 311 degrees C, which is an increase of 44 degrees C compared to that of c. The mechanical properties of the ANPF-BDM/quartz fiber (Qf) composites were also investigated. The results reveal that ANPF-BDM/Qf composites exhibit similar mechanical strength to APF-BDM/Qf composites at room temperature. In addition, the mechanical properties of the ANPF-BDM/ Qf composites demonstrated significant improvement in mechanical properties retained significantly improved at 200 degrees C, with a 68% flexural strength retention and a 96% interlaminar shear retention of 15-ANPF-BDM/Qf composites. Thus, ANPF-BDM/Qf composites exhibit outstanding mechanical properties at 200 degrees C. Allyl ether naphthol-modified bismaleimide resins. image
