摘要

異質複材具輕量化、高性能（耐用／強度）、可加工等特性，近年在運輸（航太／汽車／自行車）、消費性電子產品、通訊、機械設備、熱管理等產業需求大增。全球複材材料市場將由2017年4.4億美元成長至2026年12.9億美元；其中，以金屬為主的複材材料，預期2022年產值將達4.4億美元，而產量將由2012年1,900公噸成長至2022年3,400公噸。異質複材其組成可含非金屬及金屬層，相互面結合成為板、殼件，其非金屬層可為熱固或熱塑複材，相較於熱固複材為非循環再用材料，熱塑複材具備可回收再利用，預浸材料無需冷藏，加温後成形性佳等優點，其本身之熱塑性樹脂加熱軟化，常溫固化，為可逆物理反應。複材板材可經由熱成形製程產出所需曲面特徵之殼件，具有可塑性成形及量產的潛力。本文將介紹金屬中心新近發展之複材材料加熱製板、殼件熱成形製程與模具技術研究成果，以提供相關業界之參考。

Heterogeneous composite materials have the characteristics of light weight, high performance in durability and strength, and process ability. In recent years, the demand for transportation, consumer electronics, communications, mechanical equipment, thermal management and other industries has greatly increased. The global composition market will grow from USD 440 million in 2017 to 1.29 billion in 2026. Among them, metal-based composition are expected to have an output value of USD 440 million in 2022, and output will grow from 1,900 metric tons in 2012 to 3,400 metric tons in 2022. The heterogeneous composition can contain non-metallic and metal layers, which are combined with each other to form a blank and shell structure. The non-metallic layer can be a thermosetting or thermoplastic composition, which is non-recyclable compared to a thermosetting one. Thermoplastic composite material has the advantages of recyclability and good formability after heating. The required curved features of composite blank can be produced through the thermoforming process, which is suit for plastic forming and mass production. This article will introduce the composite blank and shell thermoforming process and die technology recently developed by MIRDC to provide the reference for the industries.
