PROBLEM TO BE SOLVED: To provide a test method for a hot platen precision which can be analyzed on a condition adapted to an actual molding. SOLUTION: A prepreg in which a grid like marking 1 and a circular marking 2 capable of discrimination after a heat pressurization are formed on a surface is placed between the press hot platens and is carried out the heat pressurization. Then, a variation of the grid like marking 1 and the circular marking 2 is checked after the heat pressurization, thereafter, a parallelism of the hot platen is checked. COPYRIGHT: (C)2006,JPO&NCIPI
