The main target of the modification of bismaleimide (BMI) is the improvement of the resin's fracture toughness with no, or only minor, reduction in the glass transition temperature (Tg) and the hot/wet environmental stability. In this paper, a new allyl compound modified BMI resin system has been developed for this target. The allyl novolac, coded as AF, was synthesized and characterized. The properties of the modified BMI resin and its composites have been studied in detail. Thermogravimetric analysis (TGA) in nitrogen atmosphere revealed that the modified BMI resin was stable up to 484°C. The hot/wet properties of the cured copolymer were investigated by aging it in boiling distilled water. After aging for 100h, water absorption and heat deflection temperature (HDT) were 3.2% and 277°C, respectively. |
