Composite Reinforcements

3D woven composite reinforcements preforming simulations are an unavoidable step of composite part processing. The present paper deals with thick composite fabric behavior modelling and issues arising during the numerical simulation of preforming. After the description of the independent deformation modes of initially orthotropic reinforcements, a physically motivated and invariant based hyperelastic strain energy density is introduced. This constitutive law is used to show the limitations of a classical finite element formulation in 3D fabric simulations. Tension locking is highlighted in bias extension tests and a reduced integration hexahedral finite element with specific physical hourglass stabilization is proposed. Instabilities due to the highly anisotropic behavior law, witnessed in bending dominated situations, are exposed and a stabilization procedure is initiated.

Effective Use

Woven composites have been increasingly employed in engineering applications. For effective use of woven composites in engineering applications, it is essential to fully understand the mechanical behavior. In the present study, both tensile and compressive behavior of a carbon/glass hybrid woven composite manufactured by vacuum infusion process was experimentally investigated under in-plane quasi-static loading. The experiments were performed at both the axial and off-axial directions. The results indicated that the in-plane mechanical performance of the studied composite was highly directional dependent and tension/compression asymmetric.
