摘要

混成疊層板可克服分別單獨使用各種材料的缺點。由於混成疊層板具輕量化、高性能（耐用／強度）、可加工等特性，在汽車、船舶、航空和土木工程行業受到越來越多的關注。然而對於此材料之成形條件，國內業者多以嘗試錯誤法（Try and error）進行，導致耗時耗能等問題。成形極限試驗在產品設計與製程規劃過程可先透過模擬比對應變數值，推測製程中材料是否產生缺陷，本研究依循ISO-12004-2規範製作等比例縮小試片，並依循ASTM E2218（2015）測試規範進行試驗。並將測試後之成形極限曲線配合模擬分析進行比對，此技術未來在開發混成疊層板相關產品時可先行評估再投入打樣，減少開發成本以及開發時程。

Hybrid laminates can overcome the disadvantages of using each material separately. Due to its lightweight, high performance (durability/strength), and processability properties, hybrid laminates have received increasing attention in the automotive, marine, aerospace and civil engineering industries. However, for the forming conditions of this material, domestic manufacturers mostly use the try and error method, which leads to problems such as time-consuming and energy-consuming. In the process of product design and process planning, the forming limit test can first compare the strain values through simulation, and infer whether there are defects in the material during the process. This study follows the ISO-12004-2 specification to make equal-scale test pieces and follow ASTM E2218 (2015) Test specifications to test. The forming limit curve after the test is compared with the simulation analysis. In the future, when developing products related to hybrid laminates, this technology can be evaluated first and then put into proofing, reducing development costs and development time.
