Abstract Combining method of dopamine/polyhedral oligomericsilsesquioxane (DA/POSS) was firstly performed to functionalize the surface of Kevlar (POSS-g-Kevlar@PDA, f-Kevlar) cloth. And then the corresponding f-Kevlar cloth/bisphenol A cyanate ester (BADCy) matrix wave-transparent laminated composites were successfully fabricated by the method of impregnation, lamination followed by mould pressing. The obtained wave transmission efficiency (T) of 92.0% for f-Kevlar cloth/BADCy wave-transparent laminated composites was higher than that of pristine Kevlar cloth/BADCy wave-transparent laminated composites (T of 88.4%). Flexural strength and interlaminar shear strength (ILSS) of the f-Kevlar cloth/BADCy wave-transparent laminated composites were also significantly increased to 236.3 MPa and 28.5 MPa, increased by 28.8% and 73.7%, in comparison to that of pristine Kevlar cloth/BADCy wave-transparent laminated composites (flexural strength of 183.5 MPa and ILSS of 16.4 MPa), respectively. And the corresponding glass transition temperature (Tg) and heat resistant index (THRI) of the f-Kevlar cloth/BADCy wave-transparent laminated composites was 226.3 °C and 232.8 °C, respectively.

多巴胺/POSS功能化凯夫拉布增强氰酸酯基透波层压复合材料的制备及性能

摘要 首次采用多巴胺/多面体低聚倍半硅氧烷（DA/POSS）复合方法对凯夫拉（POSS-g-Kevlar@PDA，f-Kevlar）布表面进行功能化。然后通过浸渍、层压、模压的方法成功制备了相应的f-Kevlar布/双酚A氰酸酯(BADCy)基体透波层压复合材料。f-Kevlar布/BADCy透波层压复合材料获得的透波效率（T）为92.0%，高于原始Kevlar布/BADCy透波层压复合材料（T为88.4%）。f-Kevlar布/BADCy透波层压复合材料的弯曲强度和层间剪切强度（ILSS）也显着提高到236.3 MPa和28.5 MPa，分别提高了28.8%和73.7%，分别与原始 Kevlar 布/BADCy 透波层压复合材料（弯曲强度为 183.5 MPa 和 ILSS 为 16.4 MPa）相比。而f-Kevlar布/BADCy透波层压复合材料的相应玻璃化转变温度（Tg）和耐热指数（THRI）分别为226.3℃和232.8℃。
