Abstract: |
The cylinder peel strength of honeycomb sandwich structure were studied in this paper. NH-1-2.75-72 Nomex aluminium honeycomb used as sandwich material, SW-280A/3218 glass fabric reinforced epoxy resin solidified at 130℃ were selected for skin. FM 73M and SY-24C-300 adhesive film for bonding skin and honeycomb. By applying one step autocalve and one step oven cure cycle,The honeycomb sandwich structure were produced. The cylinder peel strength were tested. The material of honeycomb sandwich structure has been used in manufacturing large-scale flat radome. |
Key words: honeycomb sandwich structure;cylinder peel strength;NH-1-2.75-72 Nomex honeycomb |
