Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

Quasi-static and low-velocity impact behavior of intraply hybrid flax/basalt composites [PDF]

, 2019
In an attempt to increase the low-velocity impact response of natural fiber composites, a new hybrid intraply woven fabric based on flax and basalt fibers has been used to manufacture laminates with both thermoplastic and thermoset matrices.

Fiber reorientation in hybrid helicoidal composites

Journal of the Mechanical Behavior of Biomedical Materials, 2020
Naturally occurring biological materials with stiff fibers embedded in a ductile matrix are commonly known to achieve excellent balance between stiffness, strength and ductility. In particular, biological composite materials with helicoidal architecture have been shown to exhibit enhanced damage tolerance and increased impact energy absorption. However,

Hybrid fiber alterations in exercising seniors suggest contribution to fast‐to‐slow muscle fiber shift

Journal of Cachexia, Sarcopenia and Muscle, 2019
Background Human skeletal muscle is composed of a functional and metabolic continuum of slow (Type I) and fast fibers (IIa and IIx). Hybrid fibers co‐expressing different myosin heavy chains are also present and seem to be more prominent in aging muscle.

Effect of Glass Fiber Hybridization on the Behavior Under Impact of Woven Carbon Fiber/Epoxy Laminates [PDF]

, 2010
The low-velocity impact behavior was studied in hybrid laminates manufactured by RTM with woven carbon and glass (S2) fabrics. Specimens with different thicknesses and glass fiber content (from 0 to 21 vol.%) were tested with impact energies in the range
