چکیده

New designs for lightweight deployable structures require materials able to undergo high curvatures without damage. A possibility is the use of carbon fiber composites with a soft elastomeric matrix, such as silicone rubber. This type of composites can be folded to very high curvatures, while it retains the high axial stiffness of traditional epoxy-based composites. The reason is that the soft matrix allows the fibers on the compression side of the material to form elastic microbuckles. Through this mechanism, the composite can be subjected to a large curvature while the strain in the fibers is relatively small [4]. In this contribution we present an experimental and numerical study of this novel composite.

Folding of fiber composites with a hyperelastic matrix

This paper presents an experimental and numerical study of the folding behavior of thin composite materials consisting of carbon fibers embedded in a silicone matrix. The soft matrix allows the fibers to microbuckle without breaking and this acts as a stress relief mechanism during folding, which allows the material to reach very high curvatures. The experiments show a highly non-linear moment ...

Pitch-matrix composites for electrical, electromagnetic and strain-sensing applications

Pitch-matrix composites for deicing, electromagnetic shielding and strain sensing have been developed by using carbon fiber (discontinuous) and carbon black as electrically conductive fillers. A composite with carbon fiber (5 vol%) as the sole filler is effective for strain sensing, which functions by the electrical resistivity increasing reversibly with tensile strain. A composite with carbon ...
