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 ...

Polymer International, EarlyView.Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels
steel research international, EarlyView.The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation
European Journal of Oral Sciences, EarlyView.Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Fatigue life of high strength steel for cold forming
Metalurgija, 2017 The article presents the results of fatigue tests carried out on STRENX-type high-strength cold forming steel. For high-cycle fatigue tests carried out using low cycle loading frequencies of around 30 Hz, a ROTOFLEX machine was used. For ultra high-cycle
