Investigation of the penetration behavior of silicon dioxide epoxy hybrid nanocomposites

Abstract

The use of nanomaterials is gradually increasing with the progress of nanotechnology. In particular, the production of nanocomposites incorporating nanoparticles is one of the most significant areas in which nanomaterials are being used increasingly. The first objective of this research was to detect the punch shear or penetration resistance behavior and damage mechanisms of hybrid nanocomposites obtained by using silica (SiO2) nanoparticles. For that purpose, six different SiO2 hybrid nanocomposites with different laminations three layer (3La), 5La, 7La, 11La, 15La and 21La and different thicknesses (HC) of 0.95∼4.98 mm, were made by using vacuum assisted transfer molding (VARTM). During this research, quasi-static punch-shear (QS-PS) tests at span punch ratios (SPRs) of 1.16, 1.33, 1.67, 2.00, 2.33, 2.67, and more were conducted to determine quasi-static penetration mechanics and penetration resistance behavior. Moreover, deflection, energy dissipation, damage area, stiffness, and peak force values were investigated through experimental results and scanning electronic microscope (SEM) images.

Determination of Optimal Parameters for Silicon Dioxide Production

“…For several decades, silica remains the material of a large number of studies of scientists around the world, the main reason for which is its wide use in all industries [1][2][3][4][5], mainly as a filler and modifier of various materials: building materials, glass and carbon plastics, rubbers, plastics, epoxy resins, etc. [6][7][8][9][10][11][12][13]. Wide use is justified by high growth of technological and operational properties of materials when modifying them with silicon dioxide [14][15][16].…”
