Phthalonitrile Resin Containing Benzoxazine and Allyl Structures Copolymerized with BMI and Properties of their Quartz Fiber-Reinforced Composites

Abstract:

Copolymerization method was an efficient way to obtain polymer materials with improved performance due the combination of the advantages of each component. In this work, phthalonitrile resin containing benzoxazine and allyl structures (DBA-ph) was copolymerized with bismaleimide (BMI) and their quartz fiber (QF) reinforced composites were prepared. Results of DSC and DRA showed that DBA-ph/BMI exhibited triple-stage curing reactions and good processability. With introducing of BMI, curing reaction of DBA-ph/BMI could be initiated at lower temperature and obviously influenced by BMI content. DBA-ph/BMI/QF composites possessed relative low dielectric constants and loss, high thermal stabilities and char yield.
