Abstract

- The work concerns the inelastic response of composite preforms when subjected to large deformations. The Kawabata equipment has been used to measure the shear and bending properties of the textile reinforcements. In addition, the newly developed triaxial rheometer for out-of-plane shear and compression testing is presented and used. The triaxial rheometer is capable of simultaneous compression and two independent shear deformation modes, allowing for triaxial deformation states. Compared to previous techniques the main benefits are triaxiality, elimination of edge effects and suitability for anisotropic materials. Also, a constitutive theory for the modelling of a wide range of fibrous performs based on hypoplasticity is also presented. The experimental results indicates that even dry preforms behaves viscoelastoplastic as well as showing unsymmetrical behaviour in bending.
