Analysis of the Interfacial Bond Strength in Overmoulded Thermoplastic Composites

open access: yesPolymer Composites, EarlyView.
Two‐step injection overmoulding process investigated in this work, showing selective gate injection over a 450 mm demonstrator beam to vary flow length and rib pull‐off mechanical testing with fractographic characterisation of the overmoulded interface.

Acrylonitrile Styrene Acrylate (ASA) With Optimized Aluminum Oxide (Al2O3) Nanofiller Content for MEX Additive Manufacturing: Thermomechanical, Rheological, and Quality Metrics

open access: yesPolymer Composites, EarlyView.
Characterization processes for ASA/Al2O3 nanocomposites in MEX 3D printing. ABSTRACT As additive manufacturing (AM) continues to expand, the demand for durable components for outdoor applications is increasing. Acrylonitrile styrene acrylate (ASA), a weather‐resistant polymer, is widely used in these applications, and improving its performance could ...

Mechanical and Impact Response of Adhesively Bonded ASA/PA12 Sandwich Structures Produced by Fused Filament Fabrication

open access: yesPolymer Engineering &Science, EarlyView.
Adhesively bonded ASA/PA12 FFF sandwich structures reveal that interfacial compliance governs mechanical performance. Cyanoacrylate enhances strength but induces brittle failure, while polyurethane improves ductility and impact resistance, demonstrating that adhesive properties and stacking sequence are critical design parameters for optimizing multi ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

open access: yesJournal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.
