Combined influence of inertia, gravity, and surface tension on the linear stability of Newtonian fiber spinning

Mathias Simon Daniel Bechert

The draw resonance effect appears in fiber spinning processes if the ratio of take-up to inlet velocity, the so-called draw ratio, exceeds a critical value and manifests itself in steady oscillations of flow velocity and fiber diameter. We study the effect ...

High-temperature copolyamides obtained by the efficient transamidation of crystalline-crystalline polyamide blends

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Sylvain Cyril Claude Galland

High-performance thermoplastic composites based on semiaromatic polyamides are prime candidates for metal replacement in lightweight structural applications. However, the low ductility and toughness of semiaromatic polyamides remain major obstacles to thei ...

Twin-shaped CFRP-sandwich pedestrian bridge

Thomas Keller

A concept of a nature-inspired pedestrian bridge which tries to merge architectural, structural and manufacturing aspects in an optimized way is presented. The 18.0-m-span bridge is designed as an overhead spatial frame of a complex double-curved shape, wh ...

Environmental assessment of radical innovation in concrete structures

Emmanuel Denarié, Amir Hajiesmaeili

In the building sector, the contribution of concrete structure to the overall emissions of greenhouse gases is significant. Switzerland is engaged in a 2050 energy strategy where the reduction of the embodied energy of buildings is a key aspect. In this st ...

Rational design of fiber-reinforced hybrid composites: A global load sharing analysis

William Curtin, Varun Parameswaran Rajan

An analytical model based on global load sharing (GLS) theory is developed to guide design of fiber-reinforced hybrid composites with superior mechanical properties to single-fiber-type composites. The hybrid is assumed to comprise two types of fibers-low- ...

Thermal performance evaluation of fiber-reinforced polymer thermal breaks for balcony connections

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Kyriaki Goulouti

The potential effects of high-performance fiber-reinforced polymer thermal breaks for balcony connections on the thermal losses and heating needs of a typical residential building in Switzerland were investigated. In an optimized form, these new thermal br ...
