Quasi-static indentation analysis on three-dimensional printed continuous-fiber sandwich composites

Vishwesh Dikshit et al.

Summary: In this study, fiber reinforced sandwich structures were fabricated using fused filament fabrication and Inkjet printing techniques, and their quasi-static indentation properties were investigated. Acoustic emission signals were monitored during the indentation testing, and micro-computed tomography analysis was performed to identify failure points and damage propagation. The results showed that sinusoidal sandwich structures had the highest load-bearing capacity and energy absorption capacity, with dominant damage mechanisms being fiber pullout and core shear.

Mechanical behavior of carbon-reinforced thermoplastic sandwich composites with several core types during three-point bending tests

Walid Harizi et al.

Summary: This study investigates the bending behavior of carbon-fiber-reinforced thermoplastic sandwich composites using a mechanical-acoustic experimental coupling approach, monitoring the performance of different sandwich structures in real-time. Results show that aluminum core sandwich structures exhibit the highest stiffness, while thermoplastic PEI core sandwich structures display the best ductility and energy absorption capacity.

An experimental implementation of inverse finite element method for real-time shape and strain sensing of composite and sandwich structures

A. Kefal et al.

Summary: This study experimentally applies the inverse finite element method (iFEM) for real-time displacement reconstruction of a moderately thick wing-shaped sandwich structure using a network of strain sensors and the RZT algorithm. The results show that the iFEM approach demonstrates good consistency with traditional DIC/FEM analysis and experimental strain results.

On the determination of acoustic emission wave propagation velocity in composite sandwich structures

Yuan Wu et al.

Summary: The study focuses on determining the Acoustic Emission (AE) wave propagation velocity in composite laminate and sandwich structures using a closed-form formula. By introducing a corrective factor and correlation ratio, the calculation accuracy and relation between acoustic wave velocities are improved. Results show that the skin properties dominate the acoustic wave velocity in the sandwich, and accurate prediction of velocities in any direction can be achieved by measuring the velocity in only one direction.

Using digital image correlation for in situ strain and damage monitoring in hybrid fiber laminates under in-plane shear loading

Isa Emami Tabrizi et al.

Summary: This study investigates the use of digital image correlation system and resistive strain gauges in V-notch shear tests in fiber reinforced laminates to explore the effect of stacking sequence on spatial microdamage accumulation. Tailoring appropriate region of interest for full field strain measurement at various loading stages allows for proper monitoring of microdamage accumulation and accurate stress-strain behavior. Results show the presence of carbon plies at the surface in hybrid laminates leads to uniform strain distribution, while glass plies at the surface cause non-uniform strain distribution and potential underestimation of average shear strain. Strain maps for hybrid samples tested at 90 degrees configuration are similar regardless of stacking sequence, with damage accumulation likely related to relative volume fraction of fibers in the laminate.

A novel hybrid damage monitoring approach to understand the correlation between size effect and failure behavior of twill CFRP laminates

Raja Muhammad Awais Khan et al.

Summary: In this study, a comprehensive experimental approach using multiple structural health monitoring techniques was conducted to elucidate the size effect in twill woven carbon fiber reinforced polymeric composites. It was found that increase in thickness changes the proportion of microdamage related to fiber failures, and a stagnation period in acoustic emission activity was observed before global failure in thick samples. Moreover, the slower damage growth dynamics in thicker laminates compared to thin laminates were highlighted, assisting in understanding the size effect in laminated composites.
