Abstract
The present invention relates to a test specimen for testing the through-thickness properties of a fiber-reinforced composite material. The specimen comprises a first loading portion having a first longitudinal axis in a first plane and a second loading portion having a second longitudinal axis in a second plane. The first and second planes are substantially parallel and the first and second axes are oblique. The first and second loading portions partially overlap to form a test gauge portion that is integral with the first and second loading portions. The first loading portion extends beyond the test gauge portion in opposite directions along the first axis and the second loading portion extends beyond the gauge portion in opposite directions along the second axis. This allows a force be applied to the test gauge portion through the first and second loading portions.
