Tensile Behavior of Unidirectional Bamboo/Coir Fiber Hybrid Composites

open access: yesFibers, 2019
Natural fibers, such as bamboo, flax, hemp, and coir, are usually different in terms of microstructure and chemical composition. The mechanical properties of natural fibers strongly depend on the organization of cell walls and the cellulose micro-fibril ...

Hybrid Fiber Amplifier [PDF]

open access: yes, 2012
The advent of telecommunications in 1870s completely revolutionized the world of communications. Metallic cables consisting of twisted wire cables, co-axial cables were the media of choice for many years. These could be used efficiently up to frequencies of 10MHz but the system performance degraded beyond this range. However, with the increasing demand

Fiber reorientation in hybrid helicoidal composites

open access: yesJournal 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

open access: yesJournal 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.
