Numerous methods have recently emerged for fabricating cellular lattice structures with unit cells that can be repeated to create 3D space filling systems with very high interconnected pore fractions. These lattice structures possess exceptional mechanical strength resulting in highly efficient load supporting systems when configured as the cores of sandwich panels. These same structures also provide interesting possibilities for cross flow heat exchange. In this scenario, heat is transported from a locally heated facesheet through the lattice structure by conduction and is dissipated by a cross flow that propagates through the low flow resistant pore passages. The combination of efficient thermal conduction along the lattice trusses and low flow resistance through the pore channels results in highly efficient cross flow heat exchange. Recent research is investigating the use of hollow truss structures that enable their simultaneous use as heat pipes which significantly increases the efficiency of heat transport through the lattice and their mechanical strength. The relationships between heat transfer, frictional flow losses and topology of the lattice structure are discussed and opportunities for future developments identified.

Hydroxyapatite ceramics have been fabricated by microwave sintering in a 500 W microwave oven. Circular-plate specimens of various green densities were sintered in the oven at 1200 and 1300 °C, for 5, 10, and 20 min, respectively. Ceramics with density up to 97% of the theoretical were obtained. Density, grain size, microstructure, and strength of the ceramics sintered by microwave and by conventional methods were compared. The results show that microwave sintering of hydroxyapatite is not only highly efficient in saving time and energy, but can also improve the microstructure and thus enhance mechanical strength of the ceramics.

System A

This study was to accomplish a design process of 10-sp cassette system consisting of different material sprockets and a spider. Main purpose of this design was developing a lightweight and highly efficient cassette system for road bicycle. For this it is necessary to determine the materials and the shapes considering various important factors. Especially sprockets of 10-sp cassette system must become thinner than sprockets of low speed cassettes. Thus it is necessary to carry out a series of structural analyses so as to secure sufficient mechanical strength and rigidity. To verify the safety of this system, a series of finite element analysis was conducted under various boundary conditions. Single sprocket analysis and assembled parts separately were analyzed and compared each other. The analysis results were sufficiently satisfied. In fact how to manufacture the system must be considered.
