Abstract: |
A new kind of gluing technology was introduced for the forming of honeycomb sandwich based on hot-breaking using adhesive film. The principle, operating process, and technological parameters of the hot-break gluing technology were discussed comparing with other traditional gluing methods. Moreover, mechanical properties of the honeycomb sandwich undergoing the hot-break gluing process were studied. The results show that the hot-break gluing process contributed well-distributed adhesive to fully form strong bonding interface between honeycomb and skin, reduced the impact on pre-curing of adhesive, and improved its mechanical properties. |
