Remote Inspection of Internal Delamination in Wind Turbine Blades using Continuous Line Laser Scanning Thermography
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 7 - Trang 699-712 - 2020
This study proposes a continuous line laser scanning thermography (CLLST) system for remote inspection of internal delamination in wind turbine blades. The CLLST system offers the following advantages: (1) remote delamination inspection can be achieved by mechanically scanning a line laser beam and simultaneously capturing the corresponding thermal waves in nondestructive and noncontact manners; (......
Development of composite micro-patterns on polymer film using repetitive ultrasonic imprinting
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 1 - Trang 341-345 - 2014
Ultrasonic imprinting is a novel process in which micro-patterns can be replicated on thermoplastic polymer with short processing time and low energy consumption. Ultrasonic imprinting uses ultrasonic vibration energy to soften thermoplastic polymer, and to replicate micro-patterns on the softened polymer surface from a patterned horn or mold. In this study, a new patterning method based on ultras......
The State of the Art of Finite Element Analysis in Mechanical Clinching
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 9 - Trang 1191-1214 - 2021
Clinching technology is a mechanical connection technology that is applied to connect metal or non-metal sheet materials. It is widely used in different applications, such as automobile, aircraft, household appliances and other industries. In order to reduce weight, save energy, reduce fuel consumption, reduce pollution and curb global warming, lightweight structures with clinched joint are increa......
Study on manufacturing of recycled SiC powder from solar wafering sludge and its application
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 1 - Trang 299-304 - 2014
Slurry containing SiC powder and oil is used to cut ingots with a wire in a solar cell wafering process. The slurry, which is generally recycled due to its high price, produces a residue known as sludge during the recycling process. The sludge is mainly composed of SiC, Si, and oil. This study proposed a method to remove Si and oil from sludge to obtain a high-purity SiC powder of approximately 98......
Superhydrophobic Polymer Surface with Hierarchical Patterns Fabricated in Hot Imprinting Process
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 7 - Trang 493-503 - 2019
Superhydrophobic surfaces have been widely applied to solve environmental issues using their many functions such as drag reduction, oil–water separation and self-cleaning. It is well known that superhydrophobicity of materials can be enhanced by imparting micro/nano hierarchical patterns on its surface. Although several techniques, such as MEMS, coating, and laser ablation, have been suggested to ......
Advanced metal lift-offs and nanoimprint for plasmonic metal patterns
International Journal of Precision Engineering and Manufacturing-Green Technology - - 2014
An effective and reliable fabrication approach for silver nanostructure arrays was developed using UV nanoimprint with a lift-off resist and a Si-based etch mask for enhanced plasmonic resonance-driven device performance. Since a tapered nanopillar array is imprinted on the resist, by coating it with a Si-based etch mask layer and carrying out the etching procedure, a reverse-tapered nanohole arra......
A Review on Intense Pulsed Light Sintering Technologies for Conductive Electrodes in Printed Electronics
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 8 - Trang 327-363 - 2020
Intense pulsed light (IPL) sintering or annealing technology has attracted tremendous attention from many researchers and a variety of industries owing to its unique features. In IPL process, the pulsed white flash-light from xenon lamp is irradiated on the target materials and converts it to the desired conductive layer. The IPL process is ambient condition and room temperature process. The irrad......
Development of Multi-layer Tubular Vascular Scaffold to Enhance Compliance by Exhibiting a Negative Poisson’s Ratio
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 8 - Trang 841-853 - 2021
Synthetic small diameter vascular grafts frequently fail owing to intimal hyperplasia, results from mismatched compliance between the vascular graft and native vessels. A vascular graft with a negative Poisson's ratio (NPR, materials expand transversely when pulled axially) was suggested to enhance compliance. We produced a three-layer tubular vascular scaffold with NRP properties. The luminal sid......
Recent Progress in Strain-Engineered Stretchable Constructs
International Journal of Precision Engineering and Manufacturing-Green Technology - - Trang 1-31 - 2023
A variety of natural biological tissues (e.g., skin, ligaments, and blood vessels) exhibit a J-shaped stress–strain behavior, combining soft, compliant mechanics and large levels of stretchability together with a natural ‘strain-limiting’ mechanism to prevent damage from excessive strain. This review provides an extensive overview of recent advancements in the field of strain-engineered stretchabl......
Exergoeconomic Analysis of a Novel Zeotropic Mixture Power System
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 9 - Trang 1-24 - 2020
A parametric investigation of a novel ammonia water mixture power generation system is performed in this study. The overall performance and feasibility of the system of the proposed system are assessed from thermoeconomic, conventional exergy and advanced exergy perspectives. For better heat recovery in the existing medium-temperature heat recovery Kalina system, auxiliary solar heater is consider......
