Description

（強化繊維トウ）
トウプレグに用いる炭素繊維トウについては、何ら制限されるものではないが、炭素繊維フィラメント数が１０００〜１０００００本程度の炭素繊維トウであることが好ましい。また、本発明に使用する炭素繊維トウは、積層体表面の凹凸が減少する傾向にあることから、無撚りであることが好ましい。撚りがある場合は撚り数にして５回／ｍ以下が好ましく、２回／ｍ以下がさらに好ましい。 (Reinforced fiber tow)
The carbon fiber tow used for the tow prepreg is not limited at all, but is preferably a carbon fiber tow having about 1000 to 100,000 carbon fiber filaments. Moreover, since the carbon fiber tow used for this invention exists in the tendency for the unevenness | corrugation on the surface of a laminated body to reduce, it is preferable that it is untwisted. When there is a twist, the number of twists is preferably 5 times / m or less, more preferably 2 times / m or less.
