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.

Development of Vertical Wind Turbine Blades Using 4D Printing of Composites

Polymer Composites, EarlyView.
Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.

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

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...
