Energy-absorption Characteristics of Nacre-inspired Carbon/Epoxy Composite Tubes under Impact Loading

Both continuous square tubes and nacre-inspired composite tubes were tested under different pressure energies, respectively, under different impact energies. In addition, the specific energy absorption of QD tubes was approximately 36% higher than that of QC tubes. The improved energy absorption results were attributed to the crack deflection and parallel propagation of multiple cracks during the crushing process, according to fractographic examinations of the QD tubes.

Evaluation of delamination damage in carbon epoxy composites under swirling abrasives made by modified internal threaded nozzle

Due to their appreciable blend of high strength and low weight, Carbon fibre-reinforced polymer composites are finding increasing use in automotive manufacturing and aircraft industries. The undesirable geometrical defects inherent in abrasive jet machining of layered polymer composites are delamination and surface roughness. This investigation focuses on the delamination and surface roughness of abrasive jet machining of carbon fibre-reinforced polymer composite composites. The paper explores how to impart swirling motion to SiC abrasive particles by inserting internal threads in the newly designed nozzle, focusing on internal threads. The effect of abrasive jet parameters on the delamination factor and surface roughness was investigated. Reduce in delamination and surface roughness in carbon fiber-reinforced polymer composite composites due to maximum pressure and minimal SOD.

Numerical study to investigate the influence of CNTs on delamination resistance in broken ply carbon/epoxy composites

Ply breakage followed by interfacial delamination at the site of ply break is one of the typical failure mechanisms in fibre reinforced polymer composite laminate laminates exposed to low velocity. Improving the delamination resistance at the interface is therefore crucial, and the present research examines quantitative aspects of how adding CNTs to epoxy might increase the resistance to such delamination at the interface. Resistance to delamination has been determined by calculating the essential strain energy release rate using quadratic stress criterion and virtual crack closure integrals. The results reveal that G c is also dependent on the fiber orientation of the adjacent ply and the resin layer thickness. A significant increase in G c is observed as the resin layer thickness rises.
