Fabrication of hybrid thin ply tapes

Biomimetic fabrication of 3D structures by spontaneous folding of tapes.

This paper describes a biomimetic strategy for the fabrication of 3D structures-including an electrically functional light detector-modeled on the folding of biological macromolecules into globular shapes. The process started by fabricating precursors to 3D, millimeter-sized structures using flexible polymer tapes. These tapes were patterned with metal features supporting liquid solder, crimped...

Investigation of Mode I Delamination Resistance in Inter-ply and Intra-ply Hybrid Composites Reinforced with Basalt/Nylon Woven Fabrics

Due to their sensitivity to impact-induced delamination, woven fabric reinforced polymer composites have limited practical applications. Hybridization of polymer composites has been proposed as a solution to this problem. In this study, the effects of fiber reinforcement type, hybridization method, plies stacking sequence and loading rate on mode I delamination behavior of pure basalt, pure nyl...

Nanostructures fabrication via self-assembly of hybrid block copolymer/nanoparticles in thin film

Hierarchical nanostructure of gold nanoparticles via self-assembled block copolymer have been investigated on native oxide-terminated Si(111). Au-nanoparticles were prepared via simple wet chemical method by using Poly styrene-block-4-vinylpyridin (PS-b-P4VP) as stabiliser in nonaqueous solvents. Transmission Electron Microscopy (TEM) is used to characterise the size of the Aunanoparticles. How...

Study on Bending Damage of Intra-Ply Basalt/Nylon Hybrid Composites

Fabrication of MEMS Resonators in Thin SOI

A simple and fast process for micro-electromechanical (MEM) resonators with deep sub-micron transduction gaps in thin SOI is presented in this paper. Thin SOI wafers are important for advanced CMOS technology and thus are evaluated as resonator substrates for future cointegration with CMOS circuitry on a single chip. As the transduction capacitance scales with the resonator thickness, it is imp...
