INTERMEDIATE LAYER MATERIAL, AND COMPOSITE LAMINATE PLATE |
摘要 |
<p>Disclosed is an intermediate layer material which comprises a curable resin composition and a fiber base material and can be used for forming an intermediate layer for a composite laminate plate. When the intermediate layer material is cured, a cured product has the following properties (i) and (ii): (i) the linear expansion coefficient (E1) in the plane direction at a range from 25°C to a glass transition temperature (Tg) is 20 ppm/°C or lower; and (ii) the Barcol hardness at 25°C is 40 to 65. Also disclosed is a composite laminate plate which is formed by laminating at least one sheet of the intermediate layer material, laminating at least one sheet of a surface layer material on each of the front side and the back side of the laminated intermediate layer material, and curing the resulting laminate structure.</p> |
