Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

An Analysis of Radiographers' False Preliminary Image Evaluation Comments in One New Zealand District

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Preliminary image evaluation (PIE) comment errors were evaluated for common errors. These include missed avulsion fractures in the finger, hand, and wrist, while accessory bones in the feet and ankle were mistaken for abnormalities. Identifying these errors provides guidance for ongoing, regular, targeted training to help improve PIE accuracy rates ...

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

open access: yesPolymer 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 ...

Poly(L‐Lactide‐Co‐ε‐Caprolactone)/glass Fiber Composites: Toward Improved Mechanical Properties of Polylactide‐Based Composites

open access: yesPolymer Composites, EarlyView.
Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...

Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades

open access: yesPolymer Composites, EarlyView.
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...
