Description

本発明の繊維強化複合材料における表面のピンホールは、０．３ｍ×０．３ｍの成形品を成形し、そのパネル表面に存在する目視可能なボイド数で定義される。この際、成形時の昇温速度を１．５〜２．５℃／分の範囲に調整するとよい。 The surface pinhole in the fiber-reinforced composite material of the present invention is defined by the number of visible voids formed on a panel surface of a molded product of 0.3 m × 0.3 m. At this time, the temperature rising rate during molding may be adjusted to a range of 1.5 to 2.5 ° C./min.

（実施例３）
実施例１で用いた炭素繊維二方向クロス、樹脂組成を使用し、配合するカーボンブラックをエポキシ樹脂成分１００質量部に対して１．０質量部を含んだクロスプリプレグを作製した。その際、プリプレグ表面の樹脂層の厚みは０．５ｍｍとなるように製造条件を調節した。
(Example 3)
Using the carbon fiber bidirectional cloth and resin composition used in Example 1 , a carbon prepreg containing 1.0 part by mass of carbon black to be blended with respect to 100 parts by mass of the epoxy resin component was produced. At that time, the manufacturing conditions were adjusted so that the thickness of the resin layer on the prepreg surface was 0.5 mm.

Claims (1)

炭素繊維二方向クロス、およびカーボンブラックを含有したマトリックス樹脂からなるクロスプリプレグの製造方法であって、目付が１７０〜８００ｇ／ｍ２である炭素繊維二方向クロスを、エポキシ樹脂成分１００質量部に対して、０．０５〜１．０質量部のカーボンブラックを含有するエポキシ樹脂組成物で含浸させることによって、プリプレグ中のマトリックス樹脂の質量含有率を３０〜５０質量％とするに際して、該プリプレグ表面の樹脂層の厚みを０．１〜０．７ｍｍとすることを特徴とする、プリプレグの製造方法。 A method for producing a cross prepreg comprising a carbon fiber bi-directional cloth and a matrix resin containing carbon black, wherein the carbon fiber bi-directional cloth having a basis weight of 170 to 800 g / m 2 is obtained with respect to 100 parts by mass of an epoxy resin component. When the mass content of the matrix resin in the prepreg is 30 to 50% by mass by impregnating with an epoxy resin composition containing 0.05 to 1.0 part by mass of carbon black, the surface of the prepreg A method for producing a prepreg, wherein the resin layer has a thickness of 0.1 to 0.7 mm .
