Abstract: In this study,we prepared by adding antibacterial fungicide and without adding antibacterial fungicide honeycomb sandwich composite materials. Based on NH-1-2.75-32 Nomex honeycomb core material land mixing resin impregnated glass cloth presoak material for composite panels, the two kinds of Nomex honeycomb sandwich composite materials mechanical properties and antibacterial mouldproof performance were tested. We found that, by adding antimicrobial agent,the horizontal and longitudinal shear strength and the shear modulus were improved. Meanwhile, the aramid honeycomb composite exhibited excellent mildew antibacterial proof property, such as Escherichia coli, Staphylococcus aureus, Candida albicans,Staphylococcus epidermidis.

Key words: sandwich structure, mechanical properties, honeycomb, antibacterial mildwproof property
