Abstract Tufting of preforms increases the resistance of the laminated composites to delamination. Draping of the preforms is clearly modified by the presence of tufting threads. A simulation approach for the forming of tufted textile reinforcement stacks is proposed. It determines the state of the tufted preforms after forming and in particular the possible wrinkles. The layers of textile reinforcements are modeled by stress resultant shells. Tufting threads are modeled by rod chains that can s...

Abstract Conductive, flexible and stretchable hydrogel sensors have attracted a lot of interest in human-machine interfaces, medical monitoring, and soft robotics. However, there are still have great challenges in the preparation of conductive hydrogels with self-adhesive, self-power and antibacterial properties. In order to meet the requirements of high sensitivity, convenient carrying and anti-allergic, so as to overcome the problems of traditional sensors, such as non-stickiness, absolute dep...

Abstract Carbon aerogels derived from biomass have been considered as potential microwave absorption (MA) materials because of the intrinsic hierarchical porous structure, low density, and excellent heat resistance. However, high carbonation temperature or long carbonation time is always required to achieve optimized MA performance. Herein, the low-temperature carbonization of carbon nanotube (CNT)/cellulose aerogel was realized to develop a carbon aerogel for efficient MA. Compared with the car...

Abstract Although the fiber reinforced thermoplastic plastics (FRTP) materials has been widely applied in the automotive industry for non-load-bearing or semi-load-bearing parts, they are hardly used in load-bearing parts due to higher performance requirements. This paper focuses on an integrated design method for automotive load-bearing parts by using assembled continuous-FRTP laminates and non-continuous-FRTP materials (referred to as AFRTP). First, aiming for the lightest weight, an integrate...

Abstract Biodegradable polymers, including polybutylene adipate-co-terephthalate (PBAT), can replace traditional plastics to effectively target microplastic pollution; however, their high cost limits their application. In this study, vinyltrimethoxysilane (VTMS)-grafted lignin (VL) was prepared and incorporated into PBAT to reduce its cost and improve its mechanical properties while maintaining its biodegradability. Results show that the tensile strength, Young's modulus, and biodegradation effi...

Abstract Remote control and targeted activation are the elevated goals for shape-memory and self-healing polymers when responses to stimuli. Among so many stimuli, converting light into microstructure change or mechanical motions is now of particular interest. Herein, we report the ingenious design, synthesis and operation to advanced materials that capable of fast near-infrared (NIR) light-actuated targeted shape memory and remote accurately self-healing. Starting from biomass resources, a well...

Abstract The properties of CNT composites are known to suffer changes when exposed to space conditions or simulated space environments. A more in-depth understanding of the magnitude of those changes could help improve the design of systems that contain them, produce more accurate predictions of their performance, or even open the possibility of new applications. In this study, the electrical properties of CNT epoxy composites containing low CNT loadings (less than 1%) were measured in-situ whil...

Abstract Three-dimensional carbon honeycombs (3D C-honeycombs) are considered as a promising matrix material for new composites, while their mechanical behaviors under complex stress status remain unclear. Here, shear response of 3D C-honeycombs is systematically investigated with molecular dynamics (MD) simulations and mechanical analysis. Two deformation modes are observed for 3D C-honeycombs under in-plane and out-of-plane shear loading. A mechanical model is proposed to describe the deformat...

Abstract Flexible electronics have been extensively investigated in recent years because of their potential applications in artificial skin, soft robotics, energy storage, healthcare technology, etc. However, since the rigid and brittle nature of the conductive or semi-conductive materials, it's a huge challenge to project stretchable, self-healable and recyclable soft electronics to mimic skin. Herein, the interpenetrating and synergistic dual-network hydrogel of Diels-Alder chemistry-based dyn...
