Plain weave fabrics of polyacrylonitrile pre-oxidation yarns (PANOF) were prepared by small rapier loom. The flame retardation properties, mechanical properties and wear behaviors of PANOF plain weave fabrics were tested. The limiting oxygen index (LOI) of these PANOF plain weave fabric samples was 31%, which meets the criterion of flame-retardant fabrics. These fabrics neither melt nor shrunk when left in flame for a short period of time and the fabric structures were well maintained. Compared with flammable polyacrylonitrile fabrics, the polyacrylonitrile pre-oxidation fabrics exhibited excellent flame retardation properties, with satisfactory mechanical properties and comfortable handle.

In the present research, a micromechanical-analytical model was developed to predict the elastic properties and strength of balanced plain weave fabric composites. In this way, a new homogenization method has been developed by using a laminate analogy method for the balanced plain weave fabric composites. The proposed homogenization method is a multi-scale homogenization procedure. This model divides the representative volume element to several sub-elements, in a way that the combination of the sub-elements can be considered as a laminated composite. To determine the mechanical properties of laminates, instead of using an iso-strain assumption, the assumptions of constant in-plane strains and constant out-of-plane stress have been considered. The applied assumptions improve the accuracy of prediction of mechanical properties of balanced plain weave fabrics composites, especially the out-of-plane elastic properties. Also, the stress analysis for prediction of strain–stress behavior and strength has been implemented in a similar manner. In addition, the nonlinear mechanical behavior of balanced plain weave composite is studied by considering the inelastic mechanical behavior of its polymeric matrix. To assess the accuracy of the present model, the results were compared with available results in the literature. The results, including of engineering constants (elastic modulus and Poisson’s ratio) and stress–strain behavior show the accuracy of the present model.

AbstractIn a woven fabric composite, arrangement and behavior of the fibers contained in the yarn and the yarns themselves lead to an intricate deformation mechanism. The current research, therefore, intends to propose a simplified mathematical micromechanics model for calculating mechanical properties of the plain weave composite using finite element analysis (FEA). A repetitive volume element (RVE) cell approach has been adopted for properties evaluation of plain weave composites. The FEA allows the modeling and portrayal of fabrics by taking into account various geometric parameters such as the yarn undulation, the probability of existence of consonances in a unit cell and interaction between warp and fill tows. These factors help in generating a mesh close to the actual fabric/composite. Additionally, a technique to represent the internal layout of composite structure employing actual dimensions of yarn geometry using conventional measurement devices, rather than using the demanding method of obtaining measurements from photomicrographs of sectioned laminates, is also proposed. The geometric symmetries as reported in the available literature were also incorporated during the model formulation. The theory of comparative displacements was then used to construe these symmetries into appropriate mechanical terms. Consequently, this leads to the formulation of boundary conditions for the RVE. The proposed finite element micromechanics model is different from the existing models in a way that it defines the yarn cross-sectional path based upon computational fluid dynamics technique rather than conventionally obtained photomicrographic results or the proposed sinusoidal paths by various researchers. Experiments were then performed on the laminates used for obtaining the geometric parameters with the aim of supporting the validity of the suggested model. The results of computational analysis were found to be in good agreement with the outcomes of experimental investigation.

The present research is conducted on GFRP (Glass-Fiber Reinforced Plastic) composite which is fiberglass reinforced with epoxy matrix and find its mechanical properties that can be compared with other hybrid composite which include plain weave copper strips mesh in between the layers of fiberglass in GFRP composite. Both type of composites are made using hand layup technique i.e., placing of chopped fiberglass sheet and then epoxy resin layer by layer, after filling of epoxy and fiberglass at 20% fiber loading which is measured by digital scale, then a pressure is also applied on this sandwich. After 24 hours it is ready to be demolded and after 48 hrs. samples was cuts as per ASTM standards then testing was done on both GFRP and Hybrid composites to find their Mechanical & Physical Properties. Results shows improvement as we introduce plain weave copper strips mesh in between the GFRP laminate to make it hybrid.
