本研究係採玻璃纖維為強化材,以熱可塑性聚丙烯樹脂為基材,經由中空錠子精紡機,紡製成複合紗。再將所紡製之複合紗,以纏繞模具的方式施以熱壓成型,藉以改善複合材料之含浸效果,並探討其機械性質。 由實驗結果得知以複合紗所製成之熱可塑性複合材料,對含浸效果之改善有其正面的影響。機械性質在成型溫度為190°C∼230°C時,隨著成型時間的增加有漸升的趨勢;成型溫度在 205°C∼230°C時,則隨著成型時間的增加而有降低的趨勢。
Glass fiber and polypropylene were used as the reinforced fiver and the matrix fiber in this study. The commingled yarn was spun by Hollow-spindle spinner. The wrappin mold method was employed to form the sample of hot press, and to improve immersion effect of the thermoplastic composite material and investigate their mechanical properties. The results, show that the immersion effect of the composite material manufactured using commingled yarn can be improved. The tensile strength and impact energy of the thermoplastic composite material increased with increasing treatment temperature in lower the treatment temperature region, decreased with increasing treatment temperature in higher the treatment temperature region.
