현대 산업에서 복합재료를 폭넓게 사용하고 있다. 특히 섬유를 기반으로 하여 레진으로 경화시킨 섬유 강화 플라스틱의 재료는 우수하면서도 비강도, 비강성이 뛰어난 경량화 소재로 주목받고 있다. 이 중에서도 탄소섬유를 이용한 탄소섬유강화 플라스틱은 다른 섬유와 달리 뛰어난 기계적 특성을 지녀 차량과 항공기 등 고강도와 경량성을 동시에 필요로 하는 곳에 쓰이고 있다. 본 논문에서는 탄 소섬유강화 플라스틱으로 구성된 CT시험편으로 섬유 설계에 따른 인장특성을 해석적 연구를 통해 규 명한다. 구멍을 가진 CFRP복합재료의...

This paper has prime focus on the query optimization problem in distributed database environment. Query Processing is the major concept involved in distributed system. Data that is dispersed geographically at different locations is too gathered at resulting user site. There are many different execution actions that lead to same query result but differ in the cost incurred in query processing. We have to consider the execution strategy that yields optimal result. Communication cost is the major...

Electrical energy can be converted into heat energy through ohmic joule heating. Metallic materials are typically used in electrical heating elements because of their great electrical conductivity. However, metallic materials have several weaknesses, such as corrosion susceptibility, heavy weight, high manufacturing costs, and electromagnetic wave emissions [1,2]. To resolve these problems, carbon materials with good electrical conductivity, such as carbon fibers, graphite fibers, carbon...

that have attracted much interest in the aerospace industry, but their high manufacturing cost and low yield are still problems that prevent their wide applications in practice. This paper presents a laser-based process for graphitization of carbon fiber (CF) and explores the effect of laser radiation on the microstructure of CF. The obtained Raman spectra indicate that the outer surface of CF evolves from turbostratic structures into a three-dimensional ordered state after being irradiated by a...

Polyacrylonitrile/pitch nanofibers were prepared by electrospinning as a precursor for a gas sensor material. Pitch nanofibers were properly fabricated by incorporating polyacrylonitrile as an electrospinning supplement component. Polyacrylonitrile/pitch nanofibers were activated with steam at various temperatures followed by subsequent carbonization to make carbon nanofibers with a highly conductive graphitic structure. Steam activation was effective in facilitating gas adsorption onto the...

to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption effects of SPME fiber. This review introduces the preparation methods and applications of different kinds of carbon-based material coatings on fibers. In addition, directions for future research on carbon material composites are discussed.

Polyurethane (PU) nanofibers containing graphene oxide (GO) and Ag doped functionalized reduced graphene oxide (Ag-RGO) were successfully prepared via the electrospinning technique. The uniform distribution of GO sheets along with Ag nanoparticle in the nano?bers was investigated by scanning electron microscopy and the elemental mapping technique. X-ray diffraction and thermal gravimetric analysis veri?ed the presence of GO and Ag in the bicomposite nano?brous mats. Antibacterial tests against...

carbon fiber reinforced plastic (CFRP) to ethylene vinyl acetate (EVA) laminations. The ratios of CFRP to EVA were changed from 10:0 (pure CFRP) to 9:1, 8:2, 6:4, and 5:5 by manufacturing five different types of samples, and at the same time, the mechanical/thermal properties were analyzed with thermo-graphic images. As the ratio of the CFRP lamination was increased, in which the energy absorbance is dispersed by the fibers, it was more likely for the brittle failure mode to occur. In the cases...
