FIBER-REINFORCED SHEET

PROBLEM TO BE SOLVED: To provide a fiber-reinforced sheet which is reinforced biaxially so that the biaxial directions may be symmetric with respect to the longitudinal direction of the sheet. SOLUTION: The fiber-reinforced sheet 1 is produced by the following process: a fibrous sheet 3 made by unia...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fiber-reinforced sheet which is reinforced biaxially so that the biaxial directions may be symmetric with respect to the longitudinal direction of the sheet. SOLUTION: The fiber-reinforced sheet 1 is produced by the following process: a fibrous sheet 3 made by uniaxially arranging fiber bundle 2 in parallel is wrapped by sequentially turning back so as to be mutually superimposed at an angle of inclination of θ° along a pair of turn back guides 12 to obtain the objective sheet 1 composed of a first fibrous sheet layer 4 with an angle of +θ and a second fibrous sheet layer 5 with an angle of -θ° with the longitudinal direction of the final sheet 1.
