Document Type and Number:

Japanese Patent JP2591814

Kind Code:

B2

Abstract:

PURPOSE:To obtain the title structure freed from inadequate torsional rigidity, by constructing at least one of plural plates integrally conjugated in a crossed state with laminate(s) of pentaxially oriented type three-dimensional fibrous yarns. CONSTITUTION:At least one of plural (2) plates 1, 2 integrally conjugated in a crossed state is constructed with laminate(s) of pentaxially oriented type three-dimensional fibrous yarns. A beam reinforced with the resultant material will give practically adequate rigidity not only under tensile or compressive load, but also under torsional load.
