    摘要: A new thermocurable composition is disclosed which comprises a Bisphenol A-type epoxy resin having a number average molecular weight of 650-1300, 10-40% by weight of the Bisphenol A-type epoxy resin having an epoxy equivalent of 180-195; 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.

    摘要: A continuous reinforcing fiber sheet in which reinforcing fibers are arranged at an arbitrary angle to the main axis. The continuous reinforcing fiber sheet is well applicable to pultrusion forming without the risk of the reinforcing fibers being dispersed. This permits use of the continuous reinforcing fiber sheet in a long fiber-reinforced plastic structural member having remarkably improved torsional rigidity. The continuous reinforcing fiber sheet 1 has a continuous resin-penetrable support sheet 2 and a reinforcing fiber layer 3 held by the resin-penetrable support sheet 2. Long reinforcing fibers 4 in the reinforcing fiber layer 3 have substantially a certain length (F) and are arranged in the longitudinal direction of the resin-penetrable support sheet 2 at a prescribed angle (&agr;) to the longitudinal direction of the resin-penetrable support sheet 2.
