Dissipative Properties of Whiskerized Layer in Modified Composites under Different Loads

The effective dissipative properties of the whiskerized layer in modified composites formed by growing special nanostructures (whiskers) on the fiber surface are studied. The whiskerized layer consists of two phases: (1) elastic inclusions (nanowhiskers); (2) viscoelastic binder. The interphase layer is assumed to be a transversally isotropic material with a symmetry axis along the whiskers. Numerical values are given for the loss modulus of the whiskerized interphase layer, under the following types of loading: shear along the whiskers; shear transverse to the whiskers; an omnidirectional load transverse to the whiskers; and uniaxial extension along the whiskers. The influence of the materials in the inclusions and the viscoelastic matrix on the effective properties of the whiskerized layer is investigated.
