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 ...
متن کاملConstitutive modeling of fiber composites with a soft hyperelastic matrix
This paper presents an experimental and numerical study of unidirectional carbon fiber composites with a silicone matrix, loaded transversally to the fibers. The experiments show nonlinear behavior with significant strain softening under cyclic loading. The numerical study uses a plane-strain finite element continuum model of the composite material in which the fiber distribution is based on ex...
متن کاملInstabilities of Hyperelastic Fiber Composites: Micromechanical Versus Numerical Analyses
Macroscopic instabilities of fiber reinforced composites undergoing large deformations are studied. Analytical predictions for the onset of instability are determined by application of a new variational estimate for the behavior of hyperelastic composites. The resulting, closed-form expressions, are compared with corresponding predictions of finite element simulations. The simulations are perfo...
متن کاملFolding and Strain Softening of Carbon Fiber Composites with an Elastomeric Matrix
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 ...
متن کاملRubber/Carbon Nanotube Nanocomposite with Hyperelastic Matrix
An elastomer is a polymer with the property of viscoelasticity, generally having notably low Young's modulus and high yield strain compared with other materials. Elastomers, in particular rubbers, are used in a wide variety of products ranging from rubber hoses, isolation bearings, and shock absorbers to tires. Rubber has good properties and is thermal and electrical resistant. We used carbon ...
