Strength of composites with long-aligned fibers: fiber–fiber and fiber–crack interaction
Composites Part B: Engineering, 1998Abstract This paper presents a finite element formulation of elasticity to model elastic fracture in composites with long aligned fibers. We have employed a B-bar type approach which is applicable to compressible as well as nearly incompressible material systems.

Fiber–fiber interaction in concentrated suspensions: Disperse fibers
Journal of Rheology, 1999A hypothesis for fiber–fiber interaction in planar randomly oriented concentrated fiber suspensions is proposed and tested. The idea is that at sufficiently high fiber concentrations, friction and lubrication at fiber–fiber contact points are the dominant interaction mechanisms.

Numbers of Fiber-to-Fiber Contacts in General Fiber Assemblies
Textile Research Journal, 1977General formulas are derived for the estimation of the number of fiber-to-fiber contacts in fiber assemblies with arbitrary distributions of orientation and fiber length. The average number of contacts per unit volume of an assembly ñv is given by [Formula: see text] where [Formula: see text] In this equation fi is the density function of ...

> MODERN ALCHEMY is changing not base metals, but polymers into gold. The manufacture of polymer fibers is one of today's fastest-expanding industries. With increasing demands for fibers for clothing, tires, space applications and a variety of other needs, the consumption of both natural and man-made fibers has increased by leaps and bounds during the ...

Application of Optical Fibers for Acoustic Fibers
Optical Fiber Sensors, 1986An analogy between guided wave properties of optical fibers and acoustic fibers is introduced. Cladded glass fibers can be used for either fiber acoustic or fiber optic waveguides or both. Sensor applications are discussed.

Low-power infrared beams, which do not harm the eyes, are the means by which free-space optics (FSO) technology transmits data through the air between transceivers, or link heads, mounted on roof-tops or behind windows. It works over distances of several hundred meters to a few kilometers, depending upon atmospheric conditions. The authors believe that

Fiber fuse effect in microstructured fibers
OFC 2003 Optical Fiber Communications Conference, 2003., 2003In this paper we report the first observation of the fuse effect in a microstructured fiber. The fiber was fabricated by drilling holes in a silica rod and subsequent drawing of a fiber with output diameter of 125 /spl mu/m. The threshold intensity of laser radiation and some features of catastrophic damage differ strongly from those for conventional ...

The role of dietary fiber in colon cancer is still not clear. Ecological studies suggested a protective role for high fiber intake, but more recent analysis shows similar intakes of dietary fiber in populations with high or low incidence of colon cancer. Case-control studies generally do not support a protective role for fiber.

Fiber sensing with photorefractive fiber
SPIE Proceedings, 2002Optical fibers have been widely used for transmitting temporal signal. However, the transmission of spatial signal has not been fully exploited. Although multimode fiber has a large space-bandwidth product, transmitting spatial signals by using a fiber is rather difficult.
