三明治蜂巢結構有效減輕結構重量、增加結構機械特性被廣泛應用於航空結構件上，三明治結構的芯材大多是選擇質量輕的材料，如Nomex®紙蜂巢結構或是發泡性高分子材料；而表面材以高強度以及高勁度的玻璃纖維或是碳纖維或是金屬板材。三明治結構主要承受整體均勻負載及整體彎曲應力。而核心製作技術及結構破壞均呈現於表面材與蜂巢結構介面的膠合技術。本研究將探討三明治蜂巢結構的膠合技術及其結果強度。實驗應用三明治蜂巢結構選用標準蜂巢板做為芯材，而表面材用手積層法以玻璃纖維及碳纖維預浸布製作層板。製程採用符合標準航空製件規範的片膠以及以環氧樹脂自製的片膠做為膠合劑。自行開發膠合方法分別以預浸纖維材與樹酯含量1:1、1:2、1:3之環氧樹脂製作膠合介面。為了分析抗彎曲模數，並與比較現行標準航空製件規範的片膠，規劃一系列材料試驗彎曲試驗。實驗結果驗證自行開發膠和技術可提高並改善三明治蜂巢結構強度，並可應用於質輕以及高性能之複合材料結構上。

Honeycomb sandwich structure has lightens of structural weight, more increases the mechanical characteristic of the structure. It has been widely used in the aviation structure. The core of the sandwich structure mostly makings of choosing quality to be light, such as Nomex® paper bee's nest structure or foaming macromolecule material. The face sheet material is made by high strength of fiberglass or prepares carbon fiber or sheet metal panel. The sandwich structure mainly bears uniform load and whole bending stress. The key manufacturing technology and structural damage appear and lie between bounding technology in material of face sheet and honeycomb core structure. This research will discuss the bounding technique between the honeycomb and fiber face sheet of sandwich structure technology and result of those bending intensity. The experiment employs the honeycomb structure of sandwich to choose the standard honeycomb board as the core. The surfaces face sheet is hand accumulates layers of fiberglass and carbon fiber prepays cloth. A standard aviation sheet of glue panel is choice to used compare sheet of glue panel that the epoxy resin makes by our self. Developed method is separately in amount of resin impregnated order to 1:1, 1:2, 1:3 of epoxy resin to fibrous material and content of epoxy resin interfaces are made by our self. In order to analyze that resist the bending modulus, and comparative current standard aviation adhesive method, plan a series of material bending test. The experimental result proves that developed adhesive technology improves the honeycomb structural strength, and can apply to the quality on lightweight high-performance composite material structure.
