“…Advanced CAD software, Pro/Engineer, is used to construct the inner fiber (cylinder) and concentric outer (matrix) cylinder as individual fiber and matrix parts which are assembled to form a composite to represent a fiber pull-out CAD model. Only a quarter of the pull-out test was modeled using Pro Engineer as the state of stresses will be symmetrical which is in line with the work carried out by Sun and Lin [10]. Then, the Pro/Engineer model was converted into a Pro/ MECHANICA model for finite element analysis.…”

Fabrication properties are strongly influenced by the proportions and properties of matrix and reinforcements. The chemical and strength characteristics of the interface between fibers and matrix are particularly important in determining the properties of the composites. The interfacial bond strength has to be sufficient for a load to be transferred from the matrix to the fibers if the composite is to be stronger. To get good interfacial bonding surface treatment, chemical method and temperature must be considered. To study the interface/interphase, it was primarily decided to prepare and test a pull-out specimen. The pull-out test was carried out for different specimens to study the effect of fiber surface roughness and embedded length of the fiber. It was carried out for different specimens, and the pattern of load v/s displacement pattern was observed. One or more peaks in the ascending part of the curve were found which shows that the debonding process is stepwise for steel polyester composite. The CAD/FEA tool was used to simulate a fiber pull-out mechanism, and the results obtained had a deviation of 5% to 8% with the experimental displacements.

“…The study of the composite simulation by FEA packages has been reported, extensively, in literature by various investigators [24][25][26][27][28]. The present problem is modeled as a core cylinder representing fiber attached with a hollow cylinder of matrix material to form a single representative volume element bonded at the surfaces between fiber and matrix as shown in Figure 2(a) without considering interphase, while core cylinder representing fiber attached with hollow cylinder of interphase which is further attached with a hollow cylinder of matrix material to form a single representative volume element bonded at the surfaces between fiber and interphase and interphase and matrix, as shown in Figure 2(b).…”

Composite materials have become a necessity in recent times due to their attractive properties. The use of natural fibers is also having enough potential in the formation of feasible composites. The use of such composites in structural application as a low cost material has created a new horizon for investigation. Jute is a stiff fiber and its application in the packaging industry as a load-bearing fiber is quite common. The structure of jute is porous and it has a tendency to absorb moisture from the atmosphere, which results in its deterioration at the interface. The theoretical model for prediction of strength for such composites having porous reinforcement is developed in the present work, by considering a hexagonal fiber packing. The area occupied by voids is considered as a region of ineffectiveness for load transfer to the fibers through the matrix. The region of interphase between fiber and matrix is introduced to represent impurities in the composite. The interphase volume and property are evaluated using a modified rule of mixture (ROM). The results are also compared with FEM results obtained using licensed package ANSYS and IDEAS, with interphase properties obtained from a theoretical model. The experiments are carried out for jute— polyester composite with variation in volume fraction from 4 to 36%. The specimens are prepared at a constant pressure of 3.43 104 N/m2 by the compression molding method and special care is taken to maintain a long continuous aligned reinforcement. The strengths of the specimen are measured as per ASTM D 3039-76. The results obtained by experiments are observed to be between 0.307 and 2.41% with the theoretical model and simulated FEM results, while it is deviating 25.87% with ROM.

“…On the other hand, the continuum-mechanics based approach is able to depict the contact and friction between materials and tools since the material property can be considered in the numerical calculation. In the micro-or meso-scale continuum models [7][8][9][10], fibers in yarns (or yarn structures in a unit cell) are modeled as three dimensional solid elements and the representative material properties are predicted. However, such micro-or meso-scale methods require the enormous computation cost.…”

Through the international corporative benchmark works, the material characterization of the woven fabric composites has been examined to better understand their mechanical properties and to provide the process design information for numerical analysis. As the second stage of the benchmark work, the double-dome geometry has been used to illustrate the effect of numerical schemes on the forming behaviors of the woven composites parts. To account for the change of fiber orientation under the large deformation, the non-orthogonal constitutive model was utilized and nonlinear friction behavior was incorporated in the simulation. The equivalent material properties based on the contact status were used for the thermo-stamping process. Furthermore, we incorporated a recently developed non-orthogonal model which captures the dependency of shear behavior of woven fabric composites on the tensions in yarns. Simulation results showed the effect of coupling on the predicted forming behavior for the double-dome parts. As numerical results, blank draw-in, punch force history and fiber orientation after forming have been compared based on various numerical models and methods.
