Experimental investigation of cold and melt crystallization of polyactic acid (PLA) and its critical influence on mechanical properties Experimentelle Untersuchungen von Kalt‐ und Schmelzkristallisation von Polyactid (PLA) und deren kritischer Einfluss auf die mechanischen Eigenschaften

Materialwissenschaft und Werkstofftechnik, EarlyView.
Based on the DSC investigations, suitable annealing temperatures were identified to promote the crystalline fraction of PLA. The 3D‐printed specimens were annealed at these crystallization temperatures. An increasing crystalline fraction led to an improvement in the material's strength.

Effects of Polyamide‐6 Bulk Plasma Treatment on Morphology, Crystallinity and Mechanical Properties of Microfibrillar Composites

Polymer Composites, EarlyView.
Microfibrillar composite containing highly oriented, plasma‐treated PA6 microfibrils embedded within the polymer matrix. ABSTRACT Plasma treatment is often used to alter chemical surface characteristics of fibers or polymers, improving dispersion of components and interfacial adhesion between incompatible constituents in composites.

Behavior of a Novel Cyclic Olefin‐Based Hot‐Melt Adhesive in CFRP Adhesive Joints Compared to Conventional Epoxy‐Based Structural Adhesives

Polymer Composites, EarlyView.
Rate‐dependent performance of composite adhesive joints using thermoset and thermoplastic adhesives, in terms of toughness and fatigue behaviour. ABSTRACT A recently developed hot‐melt adhesive (HMA) based on cyclic olefin chemistry, supplied as a transparent, non‐tacky thermoplastic film with a distinctive polymer microstructure, was evaluated in this

Rheology–Performance Framework for PA6/GO Nanocomposites via a Hybrid Processing Route

Polymer Engineering &Science, EarlyView.
Hybrid PA6/GO nanocomposites with tuned melt rheology and improved thermal–mechanical performance. ABSTRACT Balancing melt processability with stiffness and heat resistance remains a central challenge for PA6 nanocomposites. Here, graphene oxide (GO) was synthesized by a modified Hummers method and incorporated into PA6 via a hybrid route (solution ...

Enhancing the Properties of PA6 and PA6/Ionomer Scraps Blend With CaCO3 Nanoparticles: Rheological, Mechanical, Thermal, and Morphological Evaluation

Polymer Engineering &Science, EarlyView.
ABSTRACT This study investigated the effects of incorporating ionomer scraps and CaCO3 nanoparticles on the rheological, mechanical, thermal, and morphological properties of neat polyamide 6 (PA6) and a PA6/ionomer scraps (80/20) blend. The ionomer formed an immiscible dispersed phase within the PA6, acting as an impact modifier; however, it reduced ...
