Mechanical Strength of Microstructured Optical Fibers
Journal of Lightwave Technology, 2014An experimental study of the mechanical reliability of microstructured optical fibers (MOFs) is reported. Tensile tests were carried on five types of MOFs and two reference fibers, and the tensile strengths were analyzed using Weibull statistics. Optical microscopy of the surfaces of rupture allowed identifying the critical flaws and determining the ...

Statistical Theory of the Strength of Fiber Bundles
Journal of Applied Mechanics, 1983Following a review of statistical models of the failure of single fibers and bundles of these fibers, algebraic recurrence formulas are derived that generate expressions for the failure probabilities of bundles of classical fibers. One of these recurrence relations is suitable for the accurate numerical calculation of failure probabilities of bundles ...

The Fiber/Matrix Bond Strength of CFRP Deduced from the Strength Transverse to the Fibers
The Journal of Adhesion, 1995Abstract The strength transverse to the fibre (or the transverse fracture strain) of CFRP is directly related to the fibre/matrix bond strength. This enables the determination of a fibre matrix bond strength based on transverse fracture data. In crossply laminates, the transverse ply usually fails many times, so that principally these experiments ...

Journal of Nanoscience and Nanotechnology, 2010
The study for strength calculation of one direction fiber-reinforced composites and the study measuring precisely fiber orientation distribution were presented. Need the systematic study for the data base that can predict mechanical properties of composite material and fiber orientation distribution by the fiber content was not constructed.

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.

Metallurgical and Materials Transactions A, 1994
A series of single-crystal A12O3 fiber (Saphikon), reinforced Ni3Al-based composites were fabricated by a liquid metal infiltration technique, pressure casting. Tensile testing and indentation techniques have been employed to measure fiber strength and fiber/matrix interfacial debond shear stress.

Fiber Properties and Paper Fracture – Fiber Length and Fiber Strength
Trans. of the XIth Fund. Res. Symp. Cambridge, 1997, 1997Phenomenological theories on the effect of pulp fiber properties on the fracture energy of paper are discussed. The effect of fiber length and strength is clarified experimentally. Fiber length appears to affect fiber failure probability only slightly. When fiber strength is changed, the fracture energy decreases greatly with only a small increment in ...

The Strength and Weakness of Cotton Fibers
Textile Research Journal, 1951The structural reversals in cotton fibers are a preferred location of break when the fiber is ruptured in tension. With the aid of a polarizing microscope, observations were made of the fraction of fibers breaking at the reversals under various conditions of moisture content, specimen length, and chemical treatment.

Journal of the American Ceramic Society, 1987
Fine‐grained polycrystalline zirconia fibers have been formed from an acetate precursor. The fibers contained a Y 2 O 3 additive, which inhibited grain growth (grain size ≤0.5 μm) and allowed the tetragonal phase to be retained at room temperature ...

The Strength and Weakness of Cotton Fibers
Textile Research Journal, 1955Previous work has shown that the structural reversals of cotton fibers are points of weakness at which the fibers prefer to break. The present paper is concerned with the distribution of these reversals in the individual fibers and with differences in reversal frequencies for various cotton varieties.
