Instruments Charpy impact

ASTM E 23-66 was applied for the dimensions of standard specimens except that the mat reinforced specimen (GC 33 wt % ) used ASTM D 256-56. Specimens were taken from a molded plate along the longitudinal fiber direction, and V notches were cut edgewise, perpendicular to both fiber direction and molding surface. Occasionally a specimen notched on the molding surface (flatwise) was used. Tests were performed with an instrumented Charpy impact tester (10) with a 30 kg-m or 150 kg-cm capacity. Test temperatures were varied from — 196°-250°C. [Pg.375]

Instrumented Charpy impact tests on unnotched samples are conducted to determine the energy absorbing capability and dynamic fracture behaviour of the C/SiC composites. The dynamic fracture toughness (ak) is calculated using the following equation ... [Pg.177]
