摘要
双马来酰亚胺树脂（BMI）作为复合材料的树脂基具有优异的耐高温性能，因此广泛用于航空航天等高科技领域。但是，由于BMI的交联密度高、熔点高、性能脆、溶解性差等特点，不能满足加工工艺和使用性能上的需要；而通过增韧改性却可以较好地改善其性能。本文介绍了双马来酰亚胺树脂的改性原理及改性方法。
Since BMI resin shows excellent ther mal resistence , it is widely used in aircraft and aero space industry. But as is well known that BMI exhibit some shortcomings such as: higher crosslinking density and melting point, sensitive to fracture damage and dissolution difficulty, it can not meet the request of workability and application. Modified BMI resin will improve the behavior. This article introduces the modi fication principle and toughening ways of BMI.
