Abstract
The present invention relates to a Test apparatus (10) for testing the interaction between through-thickness compression and shear in a test piece (16). The apparatus comprises first and second chocks (12, 14) arranged in use to securely retain a test piece, and first and second races (18, 20) which can be controllably urged towards each other to transmit a known force to the first and second chocks. The first and second chocks and the test piece together form a substantially cylindrical body of a first diameter and. The first and second races define therebetween a substantially cylindrical space of a second diameter for accommodating the chocks, and wherein the second diameter is greater than the first diameter.

Test apparatus for testing the interaction between through-thickness compression and shear in a test piece, the apparatus comprising first and second chocks arranged in use to securely retain a test piece, and first and second races which can be controllably urged towards each other to transmit a known force to the first and second chocks, wherein the first and second chocks and the test piece together form a substantially cylindrical body of a first diameter and wherein the first and second races define therebetween a space for accommodating the chocks, and are arranged to provide a single, controllable contact point between the first chock and the first race and a single controllable contact point between the second chock and the second race.
A method of testing the interaction between through-thickness compression and shear in a test piece, the method comprising mounting the test piece between first and second chocks shaped such that the chocks and test piece together form a substantially cylindrical body having a first diameter, mounting the chocks and test piece between first and second races which define a space therebetween and arranged to provide a single, controllable contact point between the first chock and the first race and a single controllable contact point between the second chock and the second race, and urging the races towards each other so as to apply a known force to the chocks.
