Gearing Scientific has invested in a TA Instruments Pukka TMA apparatus for measuring the thermal expansion of materials even where this is very small.

Gearing Scientific says that, for example, on a recent composite sample test in three orthogonal directions, it measured slightly positive expansion in one direction, a slightly negative one in the fibre direction and a larger positive expansion in the 3rd direction.
