Nonwoven rCF/PA6 Thermoplastic Composites: Hybrid Commingled Fibers vs. Powder Impregnation—Effects on Microstructure and Mechanical Properties

open access: yesPolymer Composites, EarlyView.
Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

open access: yesPolymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

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 ...
