Educational Demonstration of the Effects of Shape and Size on the Recovery of Precompressed Plastic Material (MATI-75) - 11.22.16
Information Pending 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. Experiment Details

Space experiment MATI-75 is dedicated to the 75th anniversary of MATI - K.E.Tsiolkovsky Russian State Technological University and 150 th anniversary of the founder of the theoretical space science Konstantin Eduardovich Tsiolkovsky. It is a demonstration effect of shape recovery of blanks made from cellular polymeric materials. To demonstrate the effect of shape and size recovery and stabilization when exposing to heating and cooling in zero gravity a plastic piece precompressed on the ground. To give students and post-graduate students practical skills in staging a space experiment and conducting ground studies of foamed polymer material structure obtained in the ground and space environments.
