ISS Science for Everyone

Science Objectives for Everyone
Demonstrating the Effect of Restoring the Form of Billets Made of Cellular Polymer Materials (MATI-75) demonstrates the ability of polyurethane foam to restore and lock their shapes, sizes, and the pore structure during heating and cooling in microgravity.
Science Results for Everyone
To celebrate the 150th birthday K.E.Tsiolkovsky, for whom the K.E.Tsiolkovsky Russian State Technological University is named, researchers demonstrated that a piece of plastic exposed to heating and cooling distorts and regains its shape in the same way in both microgravity and on Earth. The distortion is most likely caused by uneven heating by thermal convection, suggesting that a method for even heating is needed in order to use these materials for practical use. Foamed polymer shaped in blocks, a MATI-75 logo and a bas-reilef of Tsiolkovsky were used, and the shape-recovery process captured on video.

Applications

Space Applications
MATI-75 focuses on 2 areas: character and kinetics of restoring the sizes and shapes of foam samples in microgravity as well as the results of the subsequent studies of their structure and properties on the ground in comparison with the results of a similar ground investigations. The data gained during the investigation can be used during the development of intelligent composite materials that have shape memory for transforming large-scale space structures.

Earth Applications
Graduate students were involved in the creation of the procedures for the MATI-75 investigation.

Results/More Information

MATI-75 demonstrated the memory of the shape and sizes of a cellular polymer material made of polyurethane foam with a specified type of open porous structure and porosity value in microgravity conditions. An analysis of photographs showed that shape restoration occurred practically the same aboard the International Space Station (ISS) and in ground conditions.

A distortion of the shape of samples was observed both aboard the ISS and in ground conditions due in large measure to a twist appearing in samples with a small cross-section (cylinders with a diameter of 10 mm). The twist of the main axis of samples was 45  5. The twist of the shape was explained, most likely, by the uneven heating of the samples, caused by the fact that the samples were heated using heating elements, located on the bottom of the case. The convective air thermal currents that occurred were unevenly distributed around the case volume and heat was unevenly transferred to the samples. In connection with this, the development of a method for evenly heating the foam in the case of their practical use to create transforming structures will be necessary. The degree of restoration of the sizes of the flight samples was slightly less in comparison with the ground samples, which may be explained by the lack of or minimal intensity of the convective currents during heating of the samples in microgravity conditions. The constituent porosities (opened and closed) of the samples vary in considerably large ranges and depend on both the height and the depth of the layer being used for the studies.
