CORE MATERIAL FOR FRP STRUCTURE, METHOD FOR MANUFACTURING CORE MATERIAL FOR FRP STRUCTURE, AND FRP STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a core material for an FRP structure which can uniformly and quickly distribute a liquid resin, a method for manufacturing the core material, and the FRP structure being excellent in surface smoothness using the core material.;SOLUTION: This core material for the FRP structure has a recess section having a depth of 0.1 to 0. 5 mm along at least one direction of the surface, and with an interval of 2 to 10 mm on at least one surface. Also, the core material for the FRP structure has a recess section having a depth of 0.1 to 0.5 mm in a direction crossing the above direction.;COPYRIGHT: (C)2008,JPO&INPIT
