There is a growing interest in exploring novel material combinations and processing technology to manufacture complex 3D shaped polymer and composite structures. In the field of prosthetics and orthotics, this need is significant with additional challenges ...
EPFL2017Soft Pneumatic Gelatin Actuator for Edible Robotics
Dario Floreano, Jamie Paik, Yegor Piskarev, Jun Shintake, Harshal Arun Sonar
We present a fully edible pneumatic actuator based on gelatin-glycerol material. The actuator is monolithic, fabricated via a molding process, and measures 90 mm in length, 20 mm in width, and 17 mm in thickness. Thanks to the material mechanical character ...
2017On the Limits of Precision Glass Molding for Diffractive Optical Elements
Diffractive optical elements (DOEs) consist of surface reliefs with dimensions in the micrometer range and nanometer precision. Two technologies dominate: Elements replicated in plastic and directly microfabricated elements in fused silica. Plastic DOEs ar ...
EPFL2017Experimental investigation into bond behavior of FRP-to-concrete under mixed-mode I/II loading
The main purpose of the current study is to investigate bond behavior of fiber reinforced polymer (FRP)-to-concrete under mixed-mode I/II loading. To attain this end, 150 × 150 × 330 mm concrete prisms were cast and strengthened by carbon fiber reinforced ...
Elsevier2017Bond Behavior of CFRP Sheets Attached to Concrete through EBR and EBROG Joints Subject to Mixed-Mode I/II Loading
The bond behavior of carbon fiber–reinforced polymer (CFRP) sheets attached to concrete surface subject to mixed-mode I/II loading through single lap-shear tests is assessed. A 63 concrete prism specimens of 150 × 150 × 330 mm were prepared through externa ...
American Society of Civil Engineers2017Precision glass molding of high-resolution diffractive optical elements
Hans Peter Herzig, Toralf Scharf, Karin Prater
The demand of high resolution diffractive optical elements (DOE) is growing. Smaller critical dimensions allow higher deflection angles and can fulfill more demanding requirements, which can only be met by using electron-beam lithography. Replication techn ...
Spie-Int Soc Optical Engineering2016Fabrication of slender elastic shells by the coating of curved surfaces
François Gallaire, Pedro Miguel Nunes Pereira de Almeida Reis, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun
Various manufacturing techniques exist to produce double-curvature shells, including injection, rotational and blow molding, as well as dip coating. However, these industrial processes are typically geared for mass production and are not directly applicabl ...
Nature Publishing Group2016Micro-structuring of glassy carbon for precision glass molding of binary diffractive optical elements
Hans Peter Herzig, Toralf Scharf, Karin Prater
Precision glass molding is a more cost efficient process for the large volume manufacturing of highly complex optical surfaces than direct manufacturing. Glassy carbon (GC) molds are used for precision glass molding, because they can be operated at tempera ...
Optical Society of America2016Multilevel Micro-Structuring of Glassy Carbon Molds for Precision Glass Molding
Hans Peter Herzig, Toralf Scharf, Karin Prater
Replication techniques for diffractive optical elements (DOEs) in soft materials such as plastic injection molding are state of the art. For precision glass molding in glasses with high transition temperatures, molds with extreme thermal resistivity, low c ...
