چکیده
|
In this study the mechanical properties of composites will be examined which made from Kenaf fabric and the hybrid fabric with a simple structure that coated with epoxy resin and nano silica particles. This fabric cotton has a different situation in terms of yarn score and the type of fiber that is used in textiles. 200 nm nano silica particles, polyethylene glycol with 200 molecular weights and ethanol with mechanical weight molecular with ratio of 6: 1 will be mixed. 60% Suspension choose according to the Silica particles. The D6264 standard test for concentrated force was carried out through the cone edge to determine the strength of each of the samples. Increasing of resistance against penetration in the Kenaf samples from the raw until impregnated with the shear thickening fluid is less than the hybrid samples. Slippage of the fibers with the change of round edge indenter to cone edge indenter has changed. Penetration by cone edge to the cloth is done with lower force that it shows the effect of slippage of fibers on the resistance of the penetration. Samples impregnated with the shear thickening fluid in compare with epoxy resin have lower resistance. Slippage of natural fibers in compare with synthetic fibers is lower and on the other hand the average of friction between fibers in the natural fibers is more than synthetic fibers.
