Special Issue Information

Dear Colleagues,

This Special Issue of Materials is devoted to “Structural Design and Mechanical Properties of Fiber Composites” to develop structural applications for textile fiber composite materials, fundamental approaches for analysis and design for tensile, shear, and flexural design are needed; the nature of fiber composite materials, the conventional fibers and nanoscale fiber composite lie in chemistry and physics in fibers and textiles, high-performance fibers and composites, carbon nanotube fibers and graphene fibers, multifunctional and multi-material fibers, environmentally friendly fibers, and fiber-related materials. This Special Issue aims to encourage the exchange of ideas among material scientists, energy/environmental/biomedical researchers, engineers, and other researchers who are active at the frontiers of all fiber-related fields. The latest knowledge on advances in theoretical, experimental, and structural design and analysis of fiber composites is also welcome.

Potential topics of interest include, but are not limited to, the following: polymer materials in the application of composite materials; functional fiber composite materials preparation and characterization; carbon fiber and its composite; fiber-reinforced composites; organic fiber composites; modification of chemical fibers and polymer materials; laboratory testing methods; laminated materials; nanotechnologies in fibers and polymers; design, fabrication, and application of nanofibers; natural fibers and biomimetic polymers; smart fibers; textiles; and wearable intelligent devices.

There are no particular restrictions on the thematic areas of this Special Issue as long as the submissions are related to the structural design and analysis of fiber composites. The readers and authors of Materials are encouraged to send their latest research studies in these areas, with an emphasis on experimental validation and empirical proof for all areas related to the structural design and analysis of fiber composites.

The continuous increase in the operating speed of rail vehicles demands higher requirements for passive safety protection and lightweight design. This paper focuses on an energy-absorbing component (circular tubes) at the end of a train. Thin-walled carbon fiber-reinforced polymer (CFRP) tubes were prepared using the filament winding process. Through a combination of sled impact tests and finite element simulations, the effects of a chamfered trigger (Tube I) and embedded trigger (Tube II) on the impact response and crashworthiness of the structure were investigated. The results showed that both triggering methods led to the progressive end failure of the tubes. Tube I exhibited a mean crush force (MCF) of 891.89 kN and specific energy absorption (SEA) of 38.69 kJ/kg. In comparison, the MCF and SEA of Tube II decreased by 21.2% and 21.9%, respectively. The reason for this reduction is that the presence of the embedded trigger in Tube II restricts the expansion of the inner plies (plies 4 to 6), thereby affecting the overall energy absorption mechanism. Based on the validated finite element model, a modeling strategy study was conducted, including the failure parameters (DFAILT/DFAILC), the friction coefficient, and the interfacial strength. It was found that the prediction results are significantly influenced by modeling methods. Specifically, as the interfacial strength decreases, the tube wall is more prone to circumferential cracking or overall buckling under axial impact. Full article
