| titleOfInvention | Reinforcing fiber base material for preform, etc., and manufacturing method of laminated body of reinforcing fiber base material, etc. |
| abstract | The present invention relates to a unidirectional reinforcing fiber base material excellent in formability, mechanical properties, and handling properties and a reinforcing material integrated by laminating a plurality of reinforcing fiber base materials that retain the shapeability of the reinforcing fiber base material. It is intended to provide a fiber substrate laminate, a preform and FRP, and to provide a method for producing such a preform and FRP with high productivity and low cost. The reinforcing fiber substrate of the present invention is a unidirectionally arranged reinforcing fiber substrate having a woven structure in which at least reinforcing fiber yarns are arranged in parallel in one direction and auxiliary yarns are arranged in the other direction, and The length L of the auxiliary yarn over one reinforcing fiber yarn measured in a state where the reinforcing fiber yarns are integrated only by the auxiliary yarn is between the width H of the reinforcing fiber yarn, L = H / cos θ (where θ is the amount of in-plane shear strain, θ is 3 ° or more and 30 ° or less), and the surface of at least one side of the unidirectionally reinforced fiber base material is An adhesive resin having a glass transition temperature Tg of 0 ° C. or more and 95 ° C. or less is attached within a range of an adhesion amount of 2 g / m 2 or more and 40 g / m 2 or less, and the adhesion form is dotted, linear or discontinuous. It is linear. The reinforcing fiber substrate laminate of the present invention is a planar reinforcing fiber substrate laminate formed by laminating a plurality of the above reinforcing fiber substrates, and the adhesive resin adhering to each reinforcing fiber substrate is facing. The reinforcing fiber base is partially bonded over the entire surface, and the maximum length of each bonded portion is 1 mm or more and the width H or less of the reinforcing fiber yarn. The preform of the present invention is obtained by shaping the reinforcing fiber base laminate, and has a reinforcing fiber volume content Vpf in the range of 45% to 62%. |
