Abstract Fundamentals of composite material technology are applied to the investigation of multi-ply cord-reinforced rubber systems as used in pneumatic tires. The stiffness parameters of such multi-ply systems are determined through the use of the elastic properties of the constituent cord and rubber components. The effects of coupling between the bending and stretching modes of deformation are discussed along with the limitations of present composite material technology as applied to soft rubbery systems. The predicted stiffness parameters are related to tread wear, obstacle envelopment, vibration, and stress analysis of tires.

Saccharomyces Kudriavzevii

Recent developments in synthetic biology enable one-step implementation of entire metabolic pathways in industrial microorganisms. A similarly radical remodelling of central metabolism could greatly accelerate fundamental and applied research, but is impeded by the mosaic organization of microbial genomes. To eliminate this limitation, we propose and explore the concept of “pathway swapping,” using yeast glycolysis as the experimental model. Construction of a “single-locus glycolysis” Saccharomyces cerevisiae platform enabled quick and easy replacement of this yeast’s entire complement of 26 glycolytic isoenzymes by any alternative, functional glycolytic pathway configuration. The potential of this approach was demonstrated by the construction and characterization of S. cerevisiae strains whose growth depended on two nonnative glycolytic pathways: a complete glycolysis from the related yeast Saccharomyces kudriavzevii and a mosaic glycolysis consisting of yeast and human enzymes. This work demonstrates the feasibility and potential of modular, combinatorial approaches to engineering and analysis of core cellular processes.

Recent Developments

High pressure processes like water-jet cutting, hydroforming or LDPE production require high pressure tubing with nominal sizes of 2 to 90 mm for pressures of up to 4,000 bar. The most common materials for these applications are either cold drawn austenitic steels type 304 / 316 or low alloy martensitic steels from the A723 series. Recent developments in material technology made it possible to increase the yield strength of the cold drawn austenitic steel from 700 MPa to 1100 MPa maintaining high toughness values, even for relatively large tube sizes. This steel grade, referred to as “HP160” (nitrogen strengthened 21Cr 10Ni 3Mn 2.5Mo stainless steel), is now increasingly being utilised in the high pressure industry. In this paper the fatigue performance of HP160 under pulsating internal pressure will be compared to fatigue results from conventional steels. The results will also be compared with the requirements of the ASME high pressure code Section VIII Division 3.

Bending Behavior

In combination with the composite material technology, add the glass fiber grid into gussasphalt deck pavement system to form glass fiber grid reinforced gussasphalt. Analysis shows that adding the grid can increase the bending performance. Three point bending test was did to do verification and results were indicate that glass fiber grid can improve the anti-bending strength and anti-bending strain in high temperature.
