| description | PROBLEM TO BE SOLVED: To provide a production method for a sheet-like semifinished product for producing FRP in which carbon fibers are oriented in the longitudinal direction.SOLUTION: A sheet-like web is formed by feeding a mixture of carbon fibers and thermoplastic conjugate fibers into a carding machine. The thermoplastic conjugate fiber is a core sheath conjugate fiber comprising a high-melting point polymer component as a core component and a low-melting point polymer component as a sheath component. A nonwoven fabric is formed by heating the sheet-like web to soften or melt only the low-melting point polymer component as the sheath component and binding carbon fibers with the core component, thereby obtaining a nonwoven fabric. The nonwoven fabric is drawn in the longitudinal direction while it is heated to the temperature only the low-melting point polymer component as the sheath component melts, thereby obtaining the sheet-like semifinished product for producing FRP in which the carbon fibers are oriented in the longitudinal direction.SELECTED DRAWING: None
【課題】 炭素繊維が長手方向に配向したＦＲＰ製造用シート状半製品を製造する方法を提供する。【解決手段】 炭素繊維と熱可塑性複合繊維の混合物をカード機に投入して、シート状ウェブを作成する。熱可塑性複合繊維は、芯成分である高融点重合体成分と鞘成分である低融点重合体成分とで構成された芯鞘型複合繊維である。シート状ウェブを加熱して、低融点重合体である鞘成分のみを軟化又は溶融させて、炭素繊維と芯成分とを結合させて不織布を作成する。この不織布を、低融点重合体成分である鞘成分のみが溶融する温度に加熱しながら、長手方向に延伸する。これにより、炭素繊維が長手方向に配向したＦＲＰ製造用シート状半製品が得られる。【選択図】 なし |
