熱塑複材熱成形與接合技術應用
Application of Thermoplastic Composite Hot Forming and Joining Technology
摘要
未來車用輕量化材料比重將會因應歐美燃料經濟與嚴苛之碳排法規可預期會逐年成長，複合材料用量將漸次提升。複合材料可區分為熱塑複材及熱固複材，其中熱塑複材因可加熱循環再使用，具有回收特性，預計未來將會因環保議題、有機會可量產性及成本降低而陸續取代熱固複材，市場需求量所占其比率將逐漸擴大。熱塑複材本身之熱塑性樹脂加熱會軟化，降至常溫固化，為可逆之物理反應，其板材可經由熱成形製程產出所需曲面特徵，具有可塑性成形及量產的潛力。在複材接合方面，除了複材本身接合外，因塑膠之硬度與金屬相比較差，目前逐漸有與金屬件作Hybrid設計結合之趨勢，本文將介紹熱塑複材加熱成形與接合製程技術研究，及金屬中心新近發展之研究成果，以提供相關業界未來可能之應用需求。

The demand for lightweight materials for vehicles will be expected to grow dramatically in response to European and American fuel economy and strict carbon emission regulations. As such the use of composite materials will gradually increase. Composite materials can be divided into two categories, namely thermoplastic and thermoset composite materials. Thermoplastic composite materials can be recycled and reused. It is expected that the thermoplastic market will expand due to environment-related concerns, demands for mass production and cost reduction. The thermoplastic material is melt processable. It will liquefy when enough heat is added and solidify when the temperature drops below its melt point. This process is reversable. Thermoplastic can be shaped and molded easily due to above mentioned features. Considering the fact that the metal is superior to thermoplastic in hardness, joining of thermoplastics and metals in hybrid design for lightweight constructions are being increasingly employed in industry. This paper introduces the technology of thermoplastic forming and joining process. Recent research and development of MIRDC in this area have been demonstrated.
