“…They demonstrated that the LWSFICs have excellent energy absorption characteristics, and their threshold load could be delayed by decreasing inner air pressure in its use to give them more space for deformation during impact loading (up to 90%). According to Ref 26, the differences in mechanical properties between the membrane surfaces of inflatable composites with woven structure and knitted structure fabric applied as reinforcement were systematically studied. The experimental results showed that the inflatable composites reinforced with woven spacer fabric have the characteristics of lighter weight and higher strength, which also means that the HDWSFICs could have better compressive strength than knitted ones.…”

High-distance woven spacer fabrics have been developed into a variety of special textile products for a wide range of applications. As a type of sandwich structure, their applications are heavily dependent on their compressive properties. In this study, the compressive properties of high-distance woven spacer flexible inflatable composites (HDWSFICs) have been evaluated by varying the indenter diameter, initial inflation pressure, and spacer yarn density. The experimental results showed that the compression process can be divided into three stages, including the Contact Stage, the Stress Transition Stage and the Densification Stage. In the Stress Transition Stage, the HDWSFICs can transform compressive load into tension stress, and especially local stress into integral stress, which can be considered a “Stress Transformer”. The existence of the spacer yarns allows the inflatable composites to bear more than three times the compressive load of the inflatable membrane material itself. The compressive modulus increases with spacer yarn density and initial inflation pressure, thus the stiffness of HDWSFICs can be designed. The findings of this study may provide ideas for the design of a “Stress Transformer” and theoretical references for the development of high-distance woven spacer inflatable composites with excellent mechanical properties.

In this paper, a fiber-reinforced resin matrix composite missile wing with a wave-transparent function is studied, which has the function of wave-transparent and meets the requirements of the mechanical properties of the missile during flight, and the missile wing structure is made of aluminum alloy, carbon fiber composite material, and glass fiber composite material, and the weight reduction is about 30.3% compared with the overall aluminum alloy structure of the missile wing. In the design process, the finite element simulation method is used, the plastic deformation of aluminum alloy is fully considered, and the antenna is built into the airfoil of glass fiber composite material, which successfully realizes the wave-transparent function of the missile wing and provides a new design idea for the composite wing.

Mechanical Behavior and Energy Dissipation of Woven and Warp-Knitted Pvc Membrane Materials under Multistage Cyclic Loading

In order to study the mechanical behavior and energy dissipation of architectural membrane materials under multistage cyclic loading, the deformation behavior, energy dissipation, and damage characteristics of four kinds of warp-knitted and woven polyvinyl chloride (PVC) membrane materials were analyzed using multistage cyclic loading experiments. The results show that, compared with the uniaxial tensile strength, the peak values of the cyclic loading and unloading of the four material samples are lower in the warp direction but higher in the fill (weft) direction. Under multistage cyclic loading, the loading and unloading moduli of the warp knitting membrane increase with the increase in fabric density. At the same fabric density, the loading modulus and the unloading modulus are smaller than those of the warp knitting material. The total absorbed strain energy, elastic strain energy, and dissipation energy of the fill samples are higher than those of the warp samples at a low load level but lower than those at a high load level. PVC membrane materials’ use strength should be controlled below a 15% stress level under long-term external force loading. In the cyclic loading process, the four PVC membrane materials are viscoelastic–plastic, so it is reasonable to define the damage variable based on the accumulation of plastic deformation.
