Modelling and finite element treatment of intra-ply shearing of woven fabric
نویسندگان
چکیده
Diaphragm forming of fibre/epoxy materials is a potential cost-effective approach in manufacturing aerospace components. Significant intra-ply shearing is essential in diaphragm forming a double-curvature geometry. In previous studies, the intra-ply shearing was addressed based on an ideal fibre reinforced fluid (IFRF) model. The IFRF model was tried in the present study for a thermoset material. However, it fails to interpret the experimental results. New models, namely general hinge model and restrained membrane model were thus suggested for intraply shearing simulations. The concept of the restrained membrane model was demonstrated using finite element simulations with determined material properties. The proposed model provided a good reproduction of the experimental results. Discussions were given on inherent limitations of the IFRF model and the effects of fibre in-plane bending. # 2003 Elsevier Science B.V. All rights reserved.

A meso-scale unit-cell based material model for a prototypical plain-woven single-ply flexible armor is developed and implemented in a material user subroutine for use in commercial explicit finite element programs. The main intent of the model is to attain computational efficiency when calculating the mechanical response of the multi-ply fabric-based flexible armor material during its impact w...
متن کاملInfluence of the Dry Woven Fabrics Meso-structure on Fabric/fabric Contact Behaviour
The first stage of the RTM process concerns the preforming of the part. During the preforming of multilayered reinforcements, frictions between the plies occur. An experimental device designed to analyse the ply/ply, ply/tool and yarn/yarn frictions has been set up. Specific contact behaviour for ply/ply friction is directly related to shocks taking place between overhanging yarns of each sampl...

Due to their sensitivity to impact-induced delamination, woven fabric reinforced polymer composites have limited practical applications. Hybridization of polymer composites has been proposed as a solution to this problem. In this study, the effects of fiber reinforcement type, hybridization method, plies stacking sequence and loading rate on mode I delamination behavior of pure basalt, pure nyl...
