Composite Reinforcement

Shear deformation of composite reinforcement is the most significant and important mechanism of material characterization. So, in-plane shear properties of composite reinforcement are important parameters for determining application and use of this category of materials. The bias extension test is frequently employed to investigate the in-plane shear behavior of composites fabrics with a length equal to or greater than twice its width. In the first part of this work, bias extension tests on non-crimp fabrics have been conducted. Force and displacement were measured and registered. From obtained data, shear angles and normalized shear forces were theoretically determined. The second part was a finite element analysis of the same test based on hypo elastic model at macroscopic scale. The software ABAQUS/Explicit was used to carry out the finite element analysis in the work.

A particular pantographic sheet, modeled as a two-dimensional elastic continuum consisting of an orthogonal lattice of continuously distributed fibers with a cycloidal texture, is introduced and investigated. These fibers conceived as embedded beams on the surface are allowed to be deformed in a three-dimensional space and are endowed with resistance to stretching, shearing, bending, and twisting. A finite element analysis directly derived from a variational formulation was performed for some explanatory tests to illustrate the behavior of the newly introduced material. Specifically, we considered tests on: (1) bias extension; (2) compressive; (3) shear; and (4) torsion. The numerical results are discussed to some extent. Finally, attention is drawn to a comparison with other kinds of orthogonal lattices, namely straight, parabolic, and oscillatory, to show the differences in the behavior of the samples due to the diverse arrangements of the fibers.
