The orb web is a spectacular evolutionary innovation that enables spiders to catch flying prey. This elegant, geometric structure is woven with silk fibers that are renowned for their superior mechanical properties. We used silk gland expression libraries to address a long-standing controversy concerning the evolution of the orb-web architecture. Contrary to the view that the orb-web design evo...

Electrospinning is a versatile method for the generation of ultrathin fibers forming highly porous mats. To extend technique to preceramic polymers, rheological properties SiCN-precursor/solvent solutions are investigated systematically control and predict non-woven morphology during electrospinning as described in article number 2100321 by Luiz F. B. Ribeiro, Günter Motz, Sergio Y. G. González...

To enhance the design process of high-performance woven fibers, it is vital to clarify evolution particle dendrites, dynamic pressure drop, and capture efficiency with respect dust loading during non-steady-state filtration process. A general element (orthogonal elliptical fibers) filter cloths numerically simulated using 3D lattice Boltzmann-cell automation (LB-CA) method, where gas dynamics s...

Abstract The accurate characterization of fabrics used in vacuum assisted resin transfer molding (VARTM) is essential order to model the flow through these porous preforms. A wide range are available for composite manufacturing VARTM and thus brings about a need opt methodology which characterizes in-plane permeability These values can then be simulations that track front progression mold filli...

We present an in-depth study of CNT growth on commercially-available woven alumina fibers, and achieve uniform growth of dense aligned CNTs on commercially-available cloths up to 5 · 10 cm in area. By systematically varying the catalyst concentration, catalyst pre-treatment time, and sample position within the tube furnace, we isolate key factors governing CNT morphology on fiber surfaces and c...

Stretchable fiber and yarn triboelectric nanogenerator are sought for such applications as wearable sensing system such as cloth communication devices, electronic textiles, and robotic sensory skin. Unfortunately, previously reported triboelectric fiber and yarn are difficult to have stretchable property. We introduce here a new type of stretchable and weavable triboelectric fibers with microdi...

Electrospinning allows the production of fibrous networks for tissue engineering, drug delivery, and wound healing in health care. It enables the production of constructs with large surface area and a fibrous morphology that closely resembles the extracellular matrix of many tissues. A fibrous structure not only promotes cell attachment and tissue formation but could also lead to very interesti...

This study represents the first works on manufacture of reinforcements for composite applications such as yarns and fabrics using a tropical fiber extracted from bast Cola Lepidota (CL) plant. Different types products were produced, including twisted untwisted woven quasi-unidirectional to samples. At each scale, experimental characterizations textile mechanical properties carried out; these ar...
