由烯丙基化合物与双马来酰亚胺（ＢＭＩ）共聚而成的Ｘ４５０２树脂，具有优良的综合性能。由Ｘ４５０２树脂的丙酮溶液与Ｔ—３００碳纤维制备的预浸料具有良好的成型工艺性。Ｔ—３００／Ｘ４５０２复合材料具有突出的抗断裂性能（ＧＩＣ＝２１５Ｊ／ｍ２）和良好的湿／热稳定性，在２００℃下具有较高的强度保持率。
X4502 resin made from allyl compound and bismaleimide (BMI) has excellent overall performance. The prepreg prepared from X4502 resin acetone solution and T-300 carbon fiber has good formability. T-300 / X4502 composites have outstanding resistance to fracture (GIC = 215 J / m2) and good wet / heat stability with high strength retention at 200 ° C.
