Abstract Aerogels excel in thermal insulation due to their porous structure, but limited mechanical strength restricts broader applications. Thus, the development of aerogel composites for equipment/personnel against and hazards extreme environments necessitates more design paradigm. Herein, a novel double‐crosslinked polyimide composite (PIAC) with an organic–inorganic hybridization approach is prepared. This composite, incorporating amino‐modified SiO 2 nanoparticles reduce...
The mechanical/thermal/electrical properties on-demand design of CNTs-reinforced nanocomposites is a key scientific issue that limits the development new-generation smart nanomaterials, and establishment corresponding unified theoretical prediction model for foundation nanocomposites. Based on equivalent medium theory (EMT) obtained by Maxwell far-field matching, modified EMT established introducing Young's modulus, thermal conductivity, electrical conductivity to thin filler-matrix's...
Abstract A CF/PEEK‐reinforced Al metal‐composite hybrid structure (CF/PEEK/Al) and CF/PEEK bar were subjected to high strain rate compression tests with a split Hopkinson pressure (SHPB). With the increase in rates, both CF/PEEK/Al showed strengthening effect, microscopic fracture surface of changes from rough smooth. In plastic rheological stage stress–strain curve, shows plateau while weakening effect. When exceeds 3800 s −1 , curve exhibits secondary wave peak. The peak values are larger...
The mimicry of human skin to detect both oncoming and physical-contacting object is great importance in the fields manufacturing, artificial robots vehicles, etc. Herein, a novel bioinspired flexible highly responsive dual-mode strain/magnetism composite sensor, which works via contact contactless modes, first fabricated by incorporating Fe3O4/silicone system into carbon fiber aerogel (CFA). distance dependence magnetic field endorses CFA/Fe3O4/silicone possible for spatial sensing due...
ABSTRACT The tissue analog targets (TATs) are widely used in biodamage and weapon damage effectiveness evaluation research. Given the issues of commonly TATs, such as low plasticity gelatin environmental pollution caused by fabrication soap, this paper innovatively proposes to use paraffin raw material for making TATs. Firstly, target samples prepared melt casting process, quasi‐static mechanical properties, antibullet corresponding ballistic characteristics obtained MTS test 7.62 mm gun...
Abstract When thermoplastic composite cylindrical shell structures are applied to large‐scale structures, their connection issues remain a challenge in engineering. Particularly, the mechanical properties and structural stability of welding areas shells under external forces critical considerations design manufacturing process. This paper prepared glass fiber/polypropylene (GFPP) complete (CCS) GFPP resistance‐welded (RWCSS) using vacuum hot‐pressing technology resistance processes. Through...
Carbon-fiber-reinforced polyetheretherketone (CF/PEEK) composites are widely utilized in aerospace, medical devices, and automotive industries, renowned for their superior mechanical properties high-temperature resistance. Despite these advantages, the thermomechanical coupling behavior of CF/PEEK under dynamic loading conditions is not well understood. This study aims to explore effects at elevated strain rates, employing Hopkinson bar impact tests scanning electron microscopy (SEM)...
Abstract ZrB 2 –SiC ceramics are the potential candidates for ultrahigh‐temperature thermal protection materials of sharp‐bodied reentry and hypersonic vehicles. However, their mechanical behaviors have been rarely reported. In present work, an testing method tensile properties is proposed. The –20 vol% SiC studied up to 1950°C in air 2050°C nitrogen atmosphere first time. stress–strain curves, Young's modulus, strength obtained. microstructure evolutions, including crystallization sintering...
Abstract Glass fiber reinforced plastics (GFRPs) is a key material for the outer protecting layer of ships as well energy storage tanks. Its ballistic and blast resistance closely related to inclusion structure its glass polyester matrix, however, detailed studies have not been reported. In this paper, shooting tests finite element simulations are both employed investigate limit velocities (V50) GFRPs reveal effects layers matrix thickness on V50.
