Unidirectional flax fiber reinforced epoxy composites (FFRC) were fabricated using a hot pressing process.The effect of stacking sequence on the impact and post-impact behavior of the sequentially FFR
Effects of processing temperature on both static and dynamic mechanicalproperties of flax fiber reinforced composites (FFRC) were investigated.Initially, thermogravimetric analysis (TGA), Fourier tran
In this paper, relative humidity and temperature dependence of mechanical degradation of natural fiber composites are studied.A theoretical model is accordingly proposed based on the nonlinear constit
Zcarbon/Yttrium Iron Garnet (C/YIG) composites with different carbon content were prepared via a facile impregnation-carbonization process.The permittivity and permeability have been studied at radio
The purpose of this study is to prepare an iron-nickel alloy layer on the surface of continuous stainless steel fibers (SSFs) to improve the magnetic properties of the SSFs using conventional electrod
Barium ferrite micro/nano fibers were successfully prepared via the electrospinning by using Dimethyl Formamide (DMF) as the solvent, poly vinyl pyrrolidone (PVP) as the spinning auxiliaries and iron
Metamaterials have aroused tremendous interests in recent years owing to their peculiar electromagnetic (EM) properties and fascinating potential applications, e.g., invisibility cloak, perfect lens,
In this paper, we studied the centrifugal casting of Ti-47.5Al-2.5V-1Cr alloy, and explored the effects of pouring temperature on the interracial reaction.Castings at 1600, 1650 and 1700 ℃ were obtain
Radar absorbing material (RAM) has been used for electromagnetic wave shielding and/or absorption, since the electromagnetic interference deeply affects the function of electrical and electronic devic
为提高C/C复合材料在高温有氧环境中的抗氧化性能,采用刷涂法+化学气相沉积法在C/C复合材料表面制备了由Zr-Si过渡层、ZrB2-SiC基主陶瓷涂层和SiC封填层组成的ZrB2-SiC陶瓷基复合涂层,并研究了涂层的微观结构及其在1500℃的等温抗氧化性能。研究结果表明,涂层总厚度在100-130 u m之间,涂层结构较为完整,没有明显的贯穿性裂纹;过渡层中的部分Zr、Si原子渗入C/C基体与炭发
