Multi-mode ultrasonic visualization of porosity in composites using a focused transducer with high sensitivity and near-surface resolution

Composites Part C: Open Access, 2021
Porosity ranging from 0.15% to 2.33% in carbon fiber-reinforced polymer composites (CFRPs) is detected and characterized by multi-mode visualizations including ultrasonic A-Scan, B-Scan, C-Scan and Tomography-Scan using a focused ultrasonic transducer ...

Effect of Heterogeneous Resin Curing Agent on Micro-mechanical Uniformity of Resin Matrix of Composites

Cailiao gongcheng, 2018
Preparation of prepregs by hot melt method is generally involved the infiltration of resin. For the epoxy resin with a heterogeneous curing system, the preparation of large thickness prepregs may be affected by the uneven distribution of curing agent.

Quantum decoherence in the entanglement entropy of a composite particle and its relationship to coarse graining in the Husimi function [PDF]

, 2015
I investigate quantum decoherence in a one-body density matrix of a composite particle consisting of two correlated particles. Because of a two-body correlation in the composite particle, quantum decoherence occurs in the one-body density matrix that has
