Single Versus Double Screw Extrusion: Impact on Mechanical Performance and Crack Resistance for a Virgin, Recycled, and Blended Polypropylene

Polymer Engineering &Science, EarlyView.
Schematic overview of the study approach and key findings. ABSTRACT To evaluate the influence of extrusion on material performance, three processing methods, single extrusion (1x Ex), double extrusion (2x Ex), and double screw compounding (C), were investigated for virgin polypropylene (vPP), recycled PP (rPP), and a blend containing 10% rPP (rPP10 ...

Effect of Crystal Polymorphism on Elastic Modulus and Hardness of Poly(Butylene 2,6‐Naphthalate) (PBN)

Polymer Engineering &Science, EarlyView.
The research provides insight into the mechanical behavior of the high‐performance polyester Poly(Butylene 2,6‐Naphthalate) containing different crystal polymorphs, adjustable by the conditions of melt‐crystallization. ABSTRACT The modulus of elasticity and hardness of poly(butylene 2,6‐naphthalate) (PBN) were investigated at different length scales ...

Performance evaluation of thick carbon fiber‐reinforced laminates manufactured using six‐magnetron microwave system

Polymer International, EarlyView.
IM7/Cycom 5320‐1 unidirectional prepreg has been used to fabricate 64‐layer laminated composites. A custom‐built six‐magnetron microwave applicator and an autoclave were employed to manufacture the composite panels. Mechanical performance of the microwave‐cured composites has been juxtaposed to autoclave‐cured composites in terms of uniaxial tensile ...

Hydrological dynamics and morphological physiognomies of Dzüdza River, Nagaland, India: A Geographical Information System‐based quantification of drainage morphometry

River, EarlyView.
Abstract The assessment of the morphometric characteristics of the Dzüdza River basin in Nagaland has been critically important for hydrological analysis, flood risk assessment, soil erosion evaluation, and sustainable regional development, owing to its strategic location on the northern fringes of the Himalayas and flanked by hills to the east.

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...
