    • A new thermosetting resin composition is disclosed which comprises a Bisphenol A-type epoxy resin having a number average molecular weight of smaller than 650 but not smaller than 450 and a ratio of the weight average molecular weight thereof to the number average molecular weight thereof of in the range of 1.3-3.0; and a curing agent capable of cross-linking the epoxy resin. The curing agent is preferably a compound represented by the following general formula: ##STR1## wherein X is --CR.sub.1 R.sub.2 --, --CO--, --COO--, --SO.sub.2 --, --SO--, --S--, --O--, --NR.sub.1 --, --SiR.sub.1 R.sub.2 -- or --POR.sub.1 -- where R.sub.1 and R.sub.2 each stands for hydrogen, a lower alkyl or a phenyl; Y and Y' each stands for hydrogen, a lower alkyl or an electron attractive group; R is a lower alkyl; and m and n each is an integer of 1-4, or a mixture thereof with a primary amine, a phenolic compound or an acid anhydride.

    • The present invention relates to a hybrid prepreg having reinforcing carbon fibers and foreign fibers. The carbon fibers have a diameter ranging from 5-30 microns and are unidirectionally arranged. The foreign fibers are composed either of single monofilaments having a diameter ranging from between about 50-150 microns or of strands formed by bundling together a plurality of single monofilaments having a diameter ranging from between about 5-50 microns. If strands are employed, they have a conversion diameter (D.sub.0) which is less than about 500 microns. The conversion diameter (D.sub.0) is represented by the following equation: ##EQU1## wherein n is the number of monofilaments used in forming the strand, and wherein d is the diameter of these monofilaments. Examples of foreign fibers which can be used when practicing this invention include boron fibers, metal fibers and organic fibers. These foreign fibers are spaced at fixed intervals, arranged in the same direction as the direction of the reinforcing carbon fibers, and positioned approximately at or near the center of the resulting prepreg. The prepreg prepared in accordance with the present invention also includes a thermosetting matrix resin in which the reinforcing carbon fibers and the foreign fibers are impregnated.
    • 本发明涉及具有增强碳纤维和外来纤维的混合预浸料。 碳纤维的直径范围为5-30微米,并且是单向排列的。 外来纤维由直径范围介于约50-150微米之间的单根单丝组成,或者通过将直径范围介于约5-50微米之间的多根单丝共同组成。 如果使用线,则它们的转化直径(D0)小于约500微米。 转化直径(D0)由以下等式表示:其中n是形成链中使用的单丝的数量,其中d是这些单丝的直径。 在实施本发明时可以使用的外来纤维的实例包括硼纤维,金属纤维和有机纤维。 这些外来纤维以固定的间隔间隔开,与增强碳纤维的方向相同的方向排列,并且大致位于所得的预浸料坯的中心附近。 根据本发明制备的预浸料还包括其中浸渍增强碳纤维和外来纤维的热固性基质树脂。
