N2 - 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.
