Dynamic mechanical analysis for rapid assessment of the time-dependent recovery behavior of shape memory polymers

Jan-Anders Edvin Maansson, John Christopher Plummer, Charly David Azra

Thermally activated shape memory polymers (SMPs) recover from a secondary shape induced by mechanical deformation to a primary equilibrium shape when they are heated to their actuation temperature. In certain applications, for example in the biomedical fie ...

Adhesion of thermoplastic polyurethane elastomer to galvanized steel

Jan-Anders Edvin Maansson, Véronique Michaud, Basile Golaz

When a thermoplastic polyurethane elastomer (TPU) is co-molded with galvanized steel, the subsequent adhesion and its durability are very sensitive to the chemical bonds created at the interface. Silane coupling primers are known for enhancing adhesion bet ...

Vacuum-bag processing of sandwich structures: role of honeycomb pressure level on skin-core adhesion and skin quality

Jan-Anders Edvin Maansson, Véronique Michaud

Non-autoclave processing of honeycomb sandwich structures generally leads to poor compaction and high porosity of the skins, along with a decreased skin-core adhesion. The pressure level inside the honeycomb cells plays an important role and is controlled ...
