本實驗係採用銅纖維為強化材，以熱可塑性樹脂耐隆6為基材，經由中空錠子精 紡機，紡製成複合紗，再將所紡製之複合紗，經梭織打樣機織造成單層及多層梭織物，以 7針橫編針織機織造成羅紋與平紋針織物，施以熱壓成型，藉由不同組織結構，不同的織 物密度，來探討其機械性質。由實驗結果得知，本文可製織高品質的銅複合紗梭織物與針 織物及其由複合紗織物所製成的熱可塑性複合材料，並可運用於電磁波遮蔽等級之熱可塑 性複合材料領域。且在245℃成型溫度及成型時間為1.5min具有最佳的抗拉伸強度及衝擊 強度。熱可塑性複合材料之機械性質隨著複合紗織物密度的增加而有上昇的趨勢。梭織物 複合材料的織物密度、組織結構均優於針織物複合材料，故梭織物複合材料之機械性質優 於針織物複合材料。
The copper fiber is used as the reinforced, and Nylon 6 as the matrix fiber in this study. Firstly, we span the uncommingled yarn by Hollow spindle spinner. We also used the hand loom to weave the single and several layers woven fabrics. We also used the 7G flat knitting machine to make the rib and plain knitted fabrics. Composites with different number of plies were fabricated using compression molding method. The effects of processing parameters, stacking sequence, and loading direction on the tensile properties and failure mechanisms of knitted fabric composites are discussed. The mechanical properties are investigated in different fabric structures and densities. Experimental results indicate that high quality knitted and woven copper fabrics can be produced, and copper thermoplastic composite materials can be manufactured by the unevenness commingled yarn fabrics. These fabrics can also applied to electromagnetic shielding quality thermoplastic composite materials. They have the best tensile strength and impact energy under the conditions of forming time 1.5min and temperature 245℃. The tensile strength and impact energy of the thermoplastic composite materials are raised with increasing the density of fabrics. The woven fabrics reinforced thermoplastic composite materials have the better tensile strength and impact energy than the knitted fabric reinforced composite materials.
