关于国防科技工业走中国特色军民融合式发展之路的思考

当前国防科技工业走军民融合式发展之路,应建立军民结合、寓军于民的武器装备科研生产体系,将国防科技工业的能力建设根植于国家工业基础之中,推进军民技术的相互转移衣科技资源共享。大力发展军民结合产业,加强宏观管理,深化体制机制改革,加紧制定军民结合战略规划。     

国动委办事机构设置存在的主要问题及对策建议

近年来,在党中央、国务院、中央军委高度重视下,各级国防动员机构建设得到了健康发展,在维护国家安全稳定、促进经济社会发展和应对多种安全威胁中发挥了重要的作用。但也应看到,国防动员体制还不够完善,特别是国动委及其办事机构的设置与担负的职能任务还存在诸多不相适应的方面：一是对国动委的定性不够准确。目前,各级国防动员委员会是由军地双方共同组成、若干领导兼职的议事协调机构,没有列入军队和地方的编制序列,缺乏应有的权威性,     

Recent progress in developing ballistic and anti-impact materials:Nanotechnology and main approaches

With increasing international and civilian conflicts, developing advanced body armor has become an emerging field in academia and industry. Nanotechnology, by means of, incorporating nanomaterials, is considered a highly effective technique to achieve this goal. It has been widely studied in defense applications owing to high strength-to-weight ratios and excellent energy absorption capability of nanomaterials. Hence, this review encompasses the latest application of nanotechnology involving nan...     

Shielding and corrosion properties of the Alloy 709 as canister material for spent nuclear fuel dry casks

The shielding and corrosion properties of the Alloy 709 advanced austenitic stainless steel have been investigated as a candidate canister material in spent fuel dry casks. The results revealed that the experimental and computational data of the linear and mass attenuation coefficients of the alloy are in good agreement, in which the attenuation coefficient values decreased with increasing photon energy.Alloy 709 was shown to exhibit the highest linear attenuation coefficient against gamma rays ...     

Natural vibration of cantilever porous twisted plate with variable thickness in different directions

In this paper, the blade is assumed to be a rotating variable thickness cantilever twisted plate structure,and the natural vibrations of variable thickness cantilever twisted plate made of metal porous material are studied. It is assumed that the thickness of the plate changes along spanwise direction and chordwise direction, respectively, and it changes in both directions. The classical thin shell theory, the first and second fundamental forms of surface and von Karman geometric relationship ar...     

The role of physical properties in explosive welding of copper to stainless steel

This paper investigates the effects of the physical properties on the microstructure and weldability of explosive welding by joining two metals with a significant contrast in thermophysical properties:stainless steel and copper. Sound welds between stainless steel and copper were obtained, and the interfacial morphology was wavy, regardless of the position of the materials. The weldability of dissimilar pairs was found to be more dependent on the relationship between the physical properties of t...     

Ballistic impact response of flexible and rigid UHMWPE textile composites: Experiments and simulations

This study elaborates on the effects of matrix rigidity on the high-velocity impact behaviour of UHMWPE textile composites using experimental and numerical methods. Textile composite samples were manufactured of a plain-weave fabric(comprising Spectra? 1000 fibres) and four different matrix materials.High-velocity impact tests were conducted by launching a spherical steel projectile to strike on the prepared samples via a gas gun. The experimental results showed that the textile composites gradu...     

Effect of interactions of two holes on tensile behavior of patch repaired carbon/epoxy woven laminates

The conventional case of patch repair involves bonding a patch over single damage/hole in the laminate.This work investigates the effect of interaction of two holes on the tensile behavior patch repaired carbon epoxy woven laminates. The specimens of [0°/45°/45°/0°] laminates were repaired with adhesively bonded two-ply [45°]2external patches. Three different cases of drilled specimens were produced with different hole arrangements viz. specimens with single central hole(SH), with two holes alig...
