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 (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.

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.
