Prediction of the Mechanical Properties of the Additive Friction Stir‐Deposited Al2219 Using Machine Learning

Materials Genome Engineering Advances, EarlyView.
In this work, three prediction machine learning (ML) models (MLP, RBF, BP) are developed to predict the ultimate tensile strength (UTS) and elongation (EL) of the AFSDed Al2219 samples. ABSTRACT Additive friction stir deposition (AFSD) is an effective method for fabricating high‐performance deposits, with process parameters directly influencing the ...

Rehabilitation paired with vagus nerve stimulation for motor function of chronic ischemic stroke patients in China: Study protocol of a multicenter randomized controlled trial (Repair Study)

Neuroprotection, EarlyView.
Mechanism of vagus nerve stimulation (VNS) paired with movement: VNS activates cholinergic nucleus basalis and noradrenergic locus coeruleus neurons, modulating motor cortex activity (light green and red areas) in a task‐specific manner during targeted movements. VNS: vagus nerve stimulation.

Water‐Borne Erosion of Reinforced Polymer Composites: Application to Shallow Offshore Marine Environment

Polymer Composites, EarlyView.
Comparison of experimental and model‐predicted erosion rates for carbon fibre‐reinforced polymer (CFRP) and glass fibre‐reinforced polymer (GFRP) under low‐velocity (2 m/s) and at varying angles and sand concentrations (0.0, 0.05, 0.4 g/L). The results demonstrate good agreement between experimental data and model predictions across different erosive ...

Effect of Designed 3D Reinforcement in Mitigating Machining Damage on CFRP Plates

Polymer Composites, EarlyView.
Effect of Edge Tufting on Surface Quality, Damage, and Mechanical Performance in CFRP Machining: A Comparative Topographical and Structural Analysis. ABSTRACT Composite materials made of carbon fiber‐reinforced epoxy (CFRP) are widely used in aerospace fields due to their high strength‐to‐weight ratio. However, due to low out‐of‐plane resistance, these

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres

Polymer Composites, EarlyView.
Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...
