Honeycomb sandwich panels (referred as composite panels) are adhesive-bonded structures between thin plate surfaces and honeycomb cores with uniformly arranged hexagons. Honeycomb sandwich panels have the features of lighter weights and higher compressive/bending stiffnesses etc. Adhesive strength between surfaces and honeycomb cores of such panel structure is considered most important for its function realization because of honeycomb core’s structural feature. In this research, adhesive strength improvements are carried out through experimental approaches by changing different bonding process and method. Pure aluminum thin plates and aluminum alloy honeycomb structures are introduced for 4-point bending experiments. Comparisons on adhesive strengths of prototype composite panels fabricated using the conventional and new approached adhesion process method were performed. Improvements on adhesive strengths, reductions of adhesive amounts and costs were confirmed from experimental results under proposed adhesion process/method for composite panels having honeycomb structures as cores.
