This study demonstrates a new and sustainable methodology for recycling continuous carbon fibers from end-of-life thermoset composite parts using Joule heating. process addresses the longstanding challenge of efficiently recovering scrap reusing them to make fresh composites. The conductive volumetrically heat up when an electric current is passed through them, which in turn rapidly heats surrounding matrix sufficiently degrade it. Fibers can be easily separated degraded after direct (DC)...
Humidity-responsive soft actuators can be driven by external stimuli and provide biomimetic environmental adaptations. Here, we report a humidity-responsive axial actuator of sulfonated polyether ether ketone which shows greatly tailorable actuation performance upon embedding graphene nanoplatelets (GNPs). Analysis the experimental data that adding only 0.5 wt % GNP increases 50% provides maximum stroke 24% work capacity 230 J/kg. In addition, facilitates faster actuation, with significantly...
Polymers that undergo shape changes in response to external stimuli can serve as actuators and offer significant potential a variety of technologies, including biomimetic artificial muscles soft robotics. Current polymer possess major challenges for various applications they often require extreme non-practical actuation conditions. Thus, exploring with new or underutilized may broaden the application polymer-based muscles. Here, we introduce an all-solid fuel-powered actuator contracts...
Nanoscale reinforcements have the potential to improve mechanical properties of fiber reinforced composite. Here, effect nanofiller morphology and dispersion in augmenting mode I fracture toughness unidirectional carbon composite materials is studied. The nanofillers used electrospun nanofibers (CNFs). Unlike most which are particulate form, CNFs exist both continuous nanofiber mat forms. This trait allowed us compare (CNFs dispersed B-staged epoxy) vs. dry mats on composites while all other...
Owing to their excellent mechanical properties, carbon fiber-reinforced polymer (CFRP) composites have a broad spectrum of applications in aerospace, civil engineering, automotive, and numerous industrial fields. Despite many advantages, the inherent lack thermal stability matrix results loss composite's properties when exposed elevated temperatures. In an effort provide protection, multilayer film composed tris(hydroxymethyl)-aminomethane (THAM)-buffered polyethylenimine (PEI) vermiculite...
Efficient and nontoxic delivery of foreign cargo into cells is a critical step in many biological studies cell engineering workflows with applications areas such as biomanufacturing cell-based therapeutics. However, effective molecular involves optimizing several experimental parameters. In the case electroporation-based intracellular delivery, there need to optimize parameters like pulse voltage, duration, buffer type, concentration for each unique application. Here, we present protocol...
Polymer artificial muscles encompass a broad research area that can address the need for soft, light and flexible actuators in many disciplines. Chemically-driven muscles, such as pH-triggered polymers, lead to significant advancements muscle performance due reversible tunable nature of actuation. In this work, size-dependent actuation pH-responsive polyacrylonitrile (PAN) fibers are investigated by addressing effect fiber radius. First, thermal stabilization temperature on was examined...
