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

Marianne Liebi, Manuel Guizar Sicairos

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 ...

Scanning Small-Angle X-ray Scattering of Injection-Molded Polymers: Anisotropic Structure and Mechanical Properties of Low-Density Polyethylene

Marianne Liebi, Manuel Guizar Sicairos

Injection molding is known to create a layered anisotropicmorphologyacross the sample thickness due to varying shear and cooling ratesduring the manufacturing process. In this study, scanning small-angleX-ray scattering was used to visualize and quantify t ...

Novel tooling for direct melt impregnation of textile with variotherm injection moulding: Methodology and proof of concept

Véronique Michaud, Vincent Werlen, Christian Rytka

Thermoplastic compression resin transfer moulding coupled with injection moulding is an appealing process for the production of thermoplastic composites. However, its implementation at an industrial scale remains challenging as variotherm injection mouldin ...

Resin Transfer molding of High-Fluidity Polyamide-6 with modified Glass-Fabric preforms

Véronique Michaud, Damiano Salvatori, Baris Çaglar, Robin Samuel Trigueira, Colin Gomez

In Resin Transfer Molding (RTM), resin precursors of thermoset or, more recently, thermoplastic polymers are generally employed, raising issues related to the chemical reaction taking place during and after part processing. In this study, already polymeriz ...

New perspectives for design of lightweight structures by using textile reinforced concrete

Aurelio Muttoni, Miguel Fernández Ruiz, Patrick Lorenzo Valeri

Nowadays, reinforced concrete (RC) is one of the most widely spread construction materials: allowing to build robust and durable structures. Traditionally, due to cover requirements of the reinforcement and to casting and vibration needs, it has yet been a ...

3D spacers enhance flow kinetics in resin transfer molding with woven fabrics

Véronique Michaud, Damiano Salvatori, Baris Çaglar

Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...

Numerically-based method for fracture characterization of Mode I-dominated two-dimensional delamination in FRP laminates

Thomas Keller, Anastasios Vassilopoulos, Aida Cameselle Molares

A new numerically-based method suitable for determining the total strain energy release rate (SERA) involved in two-dimensional (2D) Mode I-dominated delamination under opening loads in FRP laminates is presented. The method is based on the mutual dependen ...
