In-plane compressive properties of 3D braided jute/epoxy composite honeycombs
Structure-property relationships
To achieve the integrity of the honeycomb structure without interlocking or bonding, a 3D braided honeycomb structure was designed and developed using natural fiber (jute) reinforced epoxy resin. To optimize the in-plane compressive performance of 3D braided composite honeycombs,

FLAx-REinforced Aluminum (FLARE)
A Bio-Based Fiber Metal Laminate Alternative Combining Impact Resistance and Vibration Damping
Fiber metal laminates (FMLs) have mainly been used in aerospace applications with synthetic fibers. To improve their environmental credentials and address issues regarding the end-of-life of these materials, a shift to FMLs based on natural fibers can be a promising course of act

Crashworthiness in preliminary design
Mean crushing force prediction for closed-section thin-walled metallic structures
To design crash structures for disruptive aircraft designs, it is required to have fast and accurate methods that can predict crashworthiness of aircraft structures early in the design phase. Axial crushing is one of the key energy absorbing mechanisms during a crash event. In th

Ageing is known to have significantly detrimental effect on mode I fatigue delamination growth (FDG) in unidirectional (UD) composite laminates. However, composite structures are usually designed with multidirectional (MD) layups, which raises the question that is it enough to on

Corrigendum to “Crashworthiness in preliminary design
Mean crushing force prediction for closed-section thin-walled metallic structures” [International Journal of Impact Engineering, Volume 188, June 2024, 104946](S0734743X24000708)(10.1016/j.ijimpeng.2024.104946)
The authors regret to inform that an error has been identified in the numerical dataset presented in the original paper (Appendix C.1) for square tubular structures. The mean force values were taken for the entire range (including the peak) instead of the plateau phase of the cru
