EQUI-DEFLECTION CANTILEVERED BEAM MATERIAL AND PRODUCTION THEREOF

摘要

PURPOSE:To provide a equi-deflection cantilevered beam material for producing a flat plate-shaped equi-deflection cantilevered lever having equi-thickness and equi-width using a continuous fiber reinforced composite material. CONSTITUTION:An equi-deflection cantilevered beam material is formed by alternately and integrally laminating first sheet members each composed of a fiber reinforced composite material wherein reinforcing continuous fibers 21 are fixed by a matrix 22 and containing continuous fibers 21a curved in the direction of an upper side 25 and second sheet members containing continuous fibers 21b curved in the direction of a lower side 26. Therefore, this beam material has such a property that the Young's modulus lowers with the increase of the angle of orientation of the continuous fibers 21 and, as a result, when a load is applied to the other end 24, the property of an equi-deflection cantilevered beam whose curvature (deflection) between one end 23 and the other end 24 is almost constant is developed.
