ーＩ−状物（プリプレグ）を複数枚積み重ね、それを金
型に挿入して加熱加圧するようにしていた。Conventionally, in order to mold a fiber-reinforced resin laminate reinforced with continuous fibers into, for example, a thick plate, a plurality of resin-impregnated continuous fiber sheets (prepreg) were stacked and inserted into a mold. It was then heated and pressurized.
しかし、このようにして成形された繊維強化樹脂積層体
は、第４図に示すように、その繊維強化樹脂積層部材４
０に強い捩り荷重Ｐを加えると、剪断応力が最も大きく
なる端部付近に眉間剥離によるクランクｄが発生する。However, as shown in FIG. 4, the fiber-reinforced resin laminate formed in this way is
When a strong torsional load P is applied to 0, a crank d occurs due to glabella peeling near the end where the shear stress is greatest.
従来、このような眉間剥離を防止するため、三次元織物
のように連続繊維シート状物の眉間を繊維によって連結
した特殊織物を使用するとか、或いは連続繊維シート状
物の眉間をステッチ加工して連結するなどして眉間剪断
強度を高めるよ・うにしていた。Conventionally, in order to prevent such peeling between the eyebrows, special fabrics such as three-dimensional fabrics in which the eyebrows of a continuous fiber sheet are connected by fibers are used, or the eyebrows of a continuous fiber sheet are stitched. The shear strength between the eyebrows was increased by connecting them.
しかし、特殊な三次元織物を作ったり、ステッチ加工し
たりすることは、それだけ余分な加工工程が必要となり
、大幅にコスト高となることは避けられない。また、特
殊な織物形状が有する制約から成形品が採りうる加工形
態にも制約が加えられることになり、成形品形状の自由
度が小さくなる等の欠点もあった。However, creating special three-dimensional fabrics and stitching requires extra processing steps, which inevitably leads to a significant increase in costs. In addition, there are also disadvantages such as restrictions on the form of processing that the molded product can take due to the limitations of the special woven fabric shape, which reduces the degree of freedom in the shape of the molded product.
（発明が解決しようとする課題］
本発明の目的は、上述した従来の繊維強化樹脂積層体が
有する欠点を解消し、コスト高を招くことなく層間剪断
強度を大幅に向上する繊維強化樹脂積層体を提供するこ

がシート自体により互いに連続した状態になっている。FIG. 1 is a sectional view showing an example of the fiber reinforced resin laminate of the present invention. This fiber-reinforced resin laminate 1 has a rectangular cross section as a whole, and is formed by endlessly winding a single continuous fiber sheet 2 in a spiral manner. Since the sheet is endlessly wound to form a rectangular shape, the laminated layers are continuous with each other at both ends of the rectangular cross section due to the sheet itself.
本発明の繊維強化樹脂積層体の断面形状は矩形断面だけ
に限定されるものでなく、用途に応じて適宜の異形断面
を採用することができる。The cross-sectional shape of the fiber-reinforced resin laminate of the present invention is not limited to only a rectangular cross-section, and an appropriately irregular cross-section can be adopted depending on the application.

Good too. Continuous fiber sheets used in this way include those based on woven or knitted fabrics impregnated with resin, as well as so-called unidirectional prepreg, in which continuous fibers aligned in one direction are impregnated with resin. There may be.
