Process-Induced Structures of Injection-Molded High-Density Polyethylene-Combining X-ray Scattering and Finite Element Modeling

The success of plastics heavily relies on fast melt processing methods used for large-scale industrial manufacturing, including injection molding. The hierarchical structure of the solid polymer depends on material selection combined with processing condit ...

Fabrication of slender elastic shells by the coating of curved surfaces

François Gallaire, Pedro Miguel Nunes Pereira de Almeida Reis, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun

Various manufacturing techniques exist to produce double-curvature shells, including injection, rotational and blow molding, as well as dip coating. However, these industrial processes are typically geared for mass production and are not directly applicabl ...

Rapid processing of net-shape thermoplastic planar random composite preforms

Véronique Michaud, Patrick Blanchard, Simon Jespersen, Daniel Schmäh

A novel thermoplastic composite preforming and moulding process is investigated to target cost issues in textile composite processing associated with trim waste, and the limited mechanical properties of current bulk flow- moulding composites. The thermopla ...

Stamp forming of carbon fibre/PA12 composites - a comparison of a reactive impregnation process and a commingled yarn system

Pierre-Etienne Bourban, Martyn Douglas Wakeman

Two forms of carbon fibre reinforced polyamide 12 (PA12) were compared during non-isothermal stamp forming. The first was a stretch broken commingled yarn woven into a fabric, studied at three initial preconsolidation levels. The second was produced by in ...

Continuous high-temperature polymerisation of methyl methacrylate

Thierry Meyer, Philip Nising

As the need for lower mol. wt. acrylates for specialty and molding applications increases, industry is looking for substitute prodn. processes. An alternative to the increasing of initiator and chain transfer agent concn. is working at higher temps. Howeve ...
