A copolymer of P(S-co-BCB-co-GMA) synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization was coated on the surface of poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibres, followed by grafting 2, 2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane (AHHFP) to obtain 6F-PBO@P-GMA fibres. The corresponding 6F-PBO@P-GMA fibres/modified cyanate ester wave-transparent laminated composites are then fabricated. The introduction of copolymer membrane and AHHFP reduces interfacial polarization and enhances the interfacial strength of the wave-transparent laminated composites. The corresponding flexural strength and interlaminar shear strength (ILSS) of the 6F-PBO@P-GMA fibres/modified cyanate ester wave-transparent laminated composites are 701.5 and 46.4 MPa, 19.3% and 12.9% higher than those of laminated composites reinforced by pristine PBO fibres, respectively. Meantime, the obtained wave-transparent laminated composites also possess the lowest complex permittivity, and wide high wave-transparent rate area at X-band (|T|² > 93.5%, thickness: 0–2.10 mm).

将通过可逆加成断裂链转移 (RAFT) 聚合合成的 P(S- co- BCB- co- GMA)共聚物涂覆在聚 ( p-亚苯基-2,6-苯并双恶唑）（PBO）纤维，然后接枝2, 2-双（3-氨基-4-羟基苯基）六氟丙烷（AHHFP）得到6F-PBO@P-GMA纤维。然后制造相应的 6F-PBO@P-GMA 纤维/改性氰酸酯透波层压复合材料。共聚物膜和AHHFP的引入降低了界面极化并增强了透波层压复合材料的界面强度。6F-PBO@P-GMA纤维/改性氰酸酯透波层压复合材料的相应弯曲强度和层间剪切强度（ILSS）分别为701.5和46.4 MPa，比原始增强的层压复合材料高19.3%和12.9%分别为 PBO 纤维。同时，所得透波层压复合材料还具有最低的复介电常数，T | ² > 93.5%，厚度：0–2.10 毫米）。
