Abstract : The study describes the IMASH-11 machine which was designed and developed at the Moscow Institute of Machine Science for the purpose of determining strength and deformation properties of sheet plastic specimens. The machine is designed for shear, tension, and compression testing in conditions of automatic programmed one-sided heating of specimens up to 1300 K with a temperature increase rate of up to 50 degrees per second in air and in an enclosed gas medium. A movable electric oven open on one side is used for maintaining the programmed temperature. Regulation of the specimen temperature is effected by automatically varying the distance between the oven and the specimen surface. The construction and the methods of conducting tests with the IMASH-11 machine are described. Results for FRP/phenol- formaldehyde and FRP/epoxy-phenol composites are presented.
