Fiber-fabric composites have the characteristics of lighter texture, higher strength, higher damage resistance, better toughness, and flexibility than laminated composites, but their complex structures have not been well studied. This paper is aimed at study the complex structure of woven fabrics in fiber art creation based on multisensor Internet of Things technology and at studying the impact of its composite material mechanical properties. In this paper, it is proposed to use glass fibers and carbon fibers to weave the required structural preforms in a two-dimensional braiding machine and then use the obtained preforms and epoxy resin to prepare three-dimensional two-dimensional braided composite materials with different structures through a molding process. The composites were tested in tension, bending, and compression to obtain data and their failure modes, and the data were compared to obtain correlations. The experimental results in this paper showed that through the tensile, bending, and compression tests of the three kinds of hybrid structure braided composites, the tensile properties of the glass fiber braided composites decreased by about 77%; the influence of angle on the bending properties of carbon fiber braided composites has the largest downward trend of 63%. Two-dimensional biaxial and two-dimensional triaxial preforms are made by weaving glass fiber and carbon fiber, and the angle deviation is basically kept within 2.2%.

Fabrication of Nanoprotrusion Surface on AISI 316 Stainless Steel via Ar–N<sub>2</sub> Plasma Etching

Argon (Ar) plasma etching of stainless steel is known to form a unique surface texture consisting of nanopillars of several hundred nanometers due to the use of carbide precipitates as a template. The present study demonstrates that adding a small amount of nitrogen (N 2 ) gas to Ar plasma discharge gas reduces the pillar size and enhances the pillar density, thereby resulting in a densely arranged nanoprotrusion surface. Admixing 1% N 2 to the discharge gas decreased the height of each nanopillar to approximately a quarter of its original height. A further increase in N 2 gas hardly changed the size of the nanoprotrusions, yet its number density increased up to 5% N 2 addition. Admixed N 2 gas generates N 2 + species in the plasma, which form tiny chromium nitride (CrN) precipitates on a stainless steel surface. These CrN precipitates have become an alternative template for plasma etching. Nanoprotrusion surfaces are expected to improve the tribological properties of stainless steel surfaces; thus, the introduced process has potential for industrial applications.
