Abstract :Subject of this paper is to provide information about mechanical behavior of a novel material to the literature: carbon fiber reinforced silicone matrix composite insert ignore into journalissuearticles values(CFRS-C);. Under a mechanical load, silicone matrix allows large elastic deformations while carbon fiber reinforcement can bear high tensile stresses. This rare behavior of CFRS-C allows us to design foldable materials without being in a bind for mechanical hinges which bring additional weights. Foldable materials are used in space structures to gain advantage of smaller volumes. In this study, CFRS-C were manufactured with two different silicone type can be found in market and one type of plain weave unidirectional carbon fiber fabric. Specimens were prepared and kept folded 90º statically in various periods of time. They were subjected to tensile testing afterwards, to investigate effect of number of layers, silicone type and duration of folding to mechanical behavior.
