摘要

纖維與金屬複合層板（Fiber metal laminate, FML）是同時利用金屬結構強度與複材輕量化等材料優勢的混合材料，以各取所長的概念可針對性的依據產品的需求，設計疊層方式及材料的選用。目前已經廣泛應用在高值化的運輸產業中，針對近來越來越嚴苛的能源法規與安全規範問題，FML製版與成形製程已是各國研發單位相繼投入的主要研究目標。本文針對目前FML的模擬分析的發展現況進行介紹，包含成形模擬資料庫建立、機械性質測試及機械性接合方式的分析，以及模擬準確度的優化等。並探討FML成形使用之模具架構，包含沖壓（stamping）、鋪疊（Lay-up）、液壓成形（hydroforming）等，進行文獻回顧與討論，並針對未來主要的研發方向進行說明。

Fiber metal laminate (FML) is a mixed material that simultaneously utilizes the strength of metal structure and the lightweight of composite materials. The material's strengths can be designed according to the needs of the product and the selection of materials. At present, it has been widely used in the high-value transportation industry. In view of the increasingly stringent energy regulations and safety regulations, FML has become the main research trend in various countries. This article introduces the current development status of the FML analysis, including the establishment of forming simulation database, the mechanical properties testing, the mechanical joining methods and the optimization of simulation accuracy. Furthermore, we discuss the mold structure commonly used in FML forming including the stamping, layup, hydroforming, etc. The literature review and discussion about future development directions are conducted.
