The invention discloses a wave-absorbing polymethacrylic acid composite resin composition, a composite resin plate and a preparation method and application thereof, and belongs to the technical field of aeronautical materials. The wave-absorbing polymethylacrylic acid composite resin composition provided by the invention comprises the following chemical components in parts by mass: 30-40 parts of a polymethylacrylic acid prepolymer; 30 parts to 40 parts of polyester fiber fabric; 25 to 35 parts of carbonyl iron powder; and 0.3 to 1.2 parts of an anti-settling agent. The polymethylacrylic acid composite resin composition provided by the invention is used for preparing a material required by a structural member between an aviation transparent structural member and a fuselage metal framework, on one hand, the material has good mechanical properties, and the load of the aviation transparent structural member is uniformly transmitted to the edge so as to effectively reduce stress concentration; therefore, the service life of the aviation transparent structural member is prolonged. And on the other hand, the material also has wave absorbing performance, and the defect that a traditional fuselage edge connecting material is poor in wave absorbing performance is overcome.
本申请公开了一种吸波聚甲基丙烯酸复合树脂组合物、复合树脂板及其制备方法与应用,属于航空材料技术领域。本申请的吸波聚甲基丙烯酸复合树脂组合物包括如下质量份的各化学组分:聚甲基丙烯酸预聚体:30份~40份;聚酯纤维织物:30份~40份;羰基铁粉:25份~35份;防沉淀剂:0.3份~1.2份。本申请提供的聚甲基丙烯酸复合树脂组合物用于制成航空透明结构件与机身金属骨架之间的结构件所需要的材料,一方面该材料具备良好力学性能,通过将航空透明结构件载荷均匀传递到边缘以有效减小应力集中,进而延长了航空透明结构件的使用寿命。另一方面,该材料还兼具吸波性能,克服了传统机身边缘连接材料吸波性能差的缺点。
