Abstract Vacuum assisted resin infusion (VARI) has attracted more and attentions in the aerospace field monitoring of process variables been one milestones for most companies. This study focuses on flow front curing degree in‐suit using a piezoelectric (PZT) sensor network. In transfer stage, propagation characteristics Lamb waves were extracted from different paths to characterize front, quadratic regression models three established. cure leaky electromechanical impedance based PZT sensors...
As is known, hybrid quadratic and subquadratic attention models in multi-head architectures have surpassed both Transformer Linear RNN , with these works primarily focusing on reducing KV complexity improving efficiency. For further research expressiveness, we introduce our series of distilled from Qwen 2.5, based pure native RWKV-7 attention, which aims to make more expressive demonstrates state tracking ability beyond transformers. We work QRWK 32B RWKV-6 architecture, another approach...
In this study, a supramolecular polymer gelator functionalized with phosphate anion, PMUS-P, has been successfully synthesized through radical polymerization, and its physicochemical, rheological properties tribological performance were carefully evaluated as gel lubricant formed non-covalent self-assembly in 500SN base oil. The results showed that the dense network structure, providing excellent stability mechanical strength. Additionally, PMUS-P exhibits good shear-thinning behavior creep...
Abstract The vacuum-assisted resin infusion (VARI) technique provides considerable advantages in manufacturing large-scale composite structures. An accurate and consecutive structural health monitoring system is urgently required to determine the initial quality assess integrity of a structure. In this paper, real-time active smart diagnostic (SDS) based on piezoelectric sensor network proposed monitor whole life-cycle Experiments were conducted carbon fiber reinforced plastic specimens with...
Abstract Vacuum-assisted resin infusion (VARI) process has been proven to be an effective-cost technology for manufacturing large-scale composite structure with complex geometries and a broad development prospect in industry fields, especially aerospace. The impregnation, crucial stage of the VARI process, can easily lead dry spots seriously reduce product quality or even scrap due improper flow. non-invasive piezoelectric sensor (NPS) network embedded (EPS) composed Stanford Multi-actuator...
Many studies have used fractal theory to characterize pore structure distribution heterogeneity through mercury intake curves. However, there is relatively little research on the model calculation of removal In this study, a high-pressure intrusion test describe and fracture (PFDH). The physical meaning curve was determined by calculating change in curve’s dimension value. results are as follows. (1) According efficiency porosity, samples can be divided into types A (mercury above 35%) B...
In this paper, an in situ piezoelectric-fiber hybrid sensor network was developed to monitor the life-cycle of carbon fiber-reinforced plastics (CFRPs), from manufacturing phase life service. The piezoelectric lead-zirconate titanate (PZT) sensors were inserted inside composite structures during process important curing parameters, including storage modulus resin and progress reaction (POR). strain that is related state measured by embedded fiber Bragg grating (FBG) sensors, gelation moment...
