For the unidirectional glass fiber reinforced plastic materials, the wedge indentaion experiments were accomplished to clarify the relation between tool and work-piece during cutting. The indenting speed was changed form 0. 01 to 10. 0 cm/min.. The main results obtained are as follows : (1) The indenting load increasing indenting speed. (2) At the high indenting speed range, the specimen broke when the wedge angle was small, while cracks appeared near the contact part between wedge face and specimen when the wedge angle became large. (3) The inclination angle of yarn to the side of rectangular specimen strongly affected the fracture of specimen. (4) The indenting speed scarcely affected both deformation of matrix and the fracture of glass fiber under the wedge face.
