Crashworthiness of poplar wood veneer tubes

R. Guelou et al.

Summary: The study found that wooden tubes have significant energy absorption performance in crash applications, especially with a specific configuration ([90/0(4)/90]). Additionally, wood has advantages such as being natural, ecological, recyclable, and low cost compared to other materials, such as composite materials.

Prediction of strength and modulus of discontinuous carbon fiber composites considering stochastic microstructure

Philip R. Barnett et al.

Summary: This paper presents a stiffness and strength laminate analogy model for discontinuous fiber composites, which successfully predicts the mechanical behavior of these composites, and applies the master ply invariant approach to them for the first time. By using constituent properties readily obtained from material datasheets, accurate predictions of strength and stiffness for discontinuous fiber composites are achieved.

Thermo-mechanical characterization of discontinuous recycled/repurposed carbon fiber reinforced thermoplastic organosheet composites

Philip R. Barnett et al.

Summary: This study focused on optimizing the performance of repurposed and recycled carbon fiber organosheet composites through multiscale material characterization and post-process annealing. The results showed that post-process annealing is an effective method for improving the mechanical properties of the composites.

Crashworthiness of recycled carbon fiber composites

Philip R. Barnett et al.

Summary: The crashworthiness of discontinuous recycled carbon fiber composites was studied by testing samples at various strain rates and temperatures, and analyzing the effects of manufacturing flaws on energy absorption capabilities. The results show great promise for discontinuous fiber organosheet composites as a novel material for automotive crash structures.
