Fiber response to pin penetration in dry woven fabric using numerical analysis

چکیده
A new type of washer with integrated pin structures was developed and presented in a previous study for the use mechanical joints fiber-reinforced plastics (FRP) metal sheets. Thereby, pin-structured significantly increases load-bearing capacity mechanically joined FRP-metal combinations. To do so, FRP hole area is to be relieved by transferring occurring loads into laminate via structures. In thermoset FRP, insertion usually leads fiber breaks. For thermoplastics (FRTP) chance failures during penetration process can reduced inserting an ultrasonic-based locally invasive heating system. By doing this, polymer molten, allowing fibers move around However, does not allow visual observation movement within process. With aim getting information about fibers, that are moved, stressed or broken depending on tip geometries, numerical investigation carried out. Therefore, 3 × twill model dry woven fabric segment based Bézier curve yarn simplifications developed. respect molten process, effect matrix neglected. consideration necessary regarding calculation time, stress distribution regular pattern damage situation could investigated. understand mechanisms behavior three different diameters angles were examined compared simulations.

Influence 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...

In this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. Fabrics are impregnated with Shear Thickening Fluid (STF). The effects of the (STF) have been considered as frictional effect. The STF has been made (Nano Silica and Polyethylene Glycol (PEG)) and then diluted by ethanol proportion of 3:1. Yarn pulling out test from in...

Impact Damage in Woven Fabric Reinforced Composites
INTRODUCTION Very often, woven fabrics are used as the reinforcement in advanced composite materials. Although the resulting inplane stiffness is lower than of their unidirectional counterparts, the excellent drapability of these materials eases the production of more general doubly curved components. In addition, the inherently low out-of-plane strength of these layered materials improves due ...
