To accurately measure the physical property value of a fiber-reinforced plastic composite material during molding and/or after molding.SOLUTION: In this system, a part or the whole of an outer periphery of an oblique-type fiber bragg grating optical fiber sensor 10 is brought into contact with a fiber-reinforced plastic composite material during molding and/or after molding, a laser beam is made to enter the oblique-type fiber bragg grating optical fiber sensor 10 to obtain a transmission spectrum, and the physical property value of the fiber-reinforced plastic composite material during molding and/or after molding is monitored on the basis of a transmission light spectrum.SELECTED DRAWING: Figure 1 【課題】成形中及び／又は成形後の繊維強化プラスチック複合材料の物性値を正確に測定すること。【解決手段】このシステムでは、成形中及び／又は成形後の繊維強化プラスチック複合材料に傾斜型ファイバブラッググレーチング光ファイバセンサ１０の外周の一部又は全部を接触させ、傾斜型ファイバブラッググレーチング光ファイバセンサ１０にレーザ光を入射して透過スペクトルを得て、透過光スペクトルに基づき成形中及び／又は成形後の繊維強化プラスチック複合材料の物性値をモニタリングする。【選択図】図１
