中文摘要 複合材料是由兩種以上的材料所構成,複合材料有許多優點,如質量輕、高強度且與其他材料相較之下有更優異的機械性質。近年來,複材於航太與汽車工業的應用也十分普遍。而無壓力釜製程因無須使用傳統的高壓熱壓釜,因此成為眾人矚目的新選擇。
本論文之研究目的為利用碳纖維預浸材和乾纖維製作出兩種複合材料,乾纖維分為編織玻璃纖維布、單向碳纖維布。第一種組合是碳纖維預浸材加上編織的玻璃纖維布,第二種為碳纖維預浸材加上單向碳纖維布,在真空袋下加熱成型。
此研究的核心乃探討含有樹脂的碳纖維預浸材於加熱時,是否能將原本在預浸布中的樹脂填滿乾纖維,並擁有適當的纖維、樹脂體積百分率與低孔隙含量之特性,我們可以利用掃描式電子顯微鏡(SEM)觀察樹脂在積層板中的分布狀況。於製程中,控制固化過程與最終成品孔隙率的最關鍵參數為適當厚度的預浸布、固化週期與良好的真空條件。
英文摘要 Composite materials are composed by two or more materials. It has various advantages of less weight and good mechanical properties compared to other materials in industry. Composites are highly popular in aerospace and automobile industries in recent years. Out of autoclave (OOA) process came into limelight as an alternative to traditional high-pressure autoclave process. The purpose of this research is to manufacture two combinations of composite materials using carbon fiber prepreg (CFRP) and dry fibers namely, woven glass fabric or unidirectional (UD) carbon fabric. Combination 1 has CFRP and woven glass fabric. Combination 2 has CFRP and UD carbon fabric. Core idea of this research is to check the feasibility of manufacturing a composite material using CFRP as a source of resin to fill the dry fibers. This is a process similar to the OOA process. Experiments were conducted to check if an acceptable fiber volume fraction in a composite laminate with less void content could be achieved. Scanning electron microscope (SEM) is used to study the resin distribution of the fabricated laminate composites. With the combination of proper thick prepreg and fiber fabrics, laminate composites with less void content could be fabricated without using the autoclave.
