Statistical Theory of the Strength of Fiber Bundles

Journal of Applied Mechanics, 1983
Following 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 ...

Fiber Properties and Paper Fracture – Fiber Length and Fiber Strength

Trans. of the XIth Fund. Res. Symp. Cambridge, 1997, 1997
Phenomenological 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 ...

Bend Strength versus Tensile Strength of Fiber‐Reinforced Ceramics

Journal of the American Ceramic Society, 1994
The bending strength of fiber‐reinforced glasses and ceramics is often observed to be higher than their tensile strength; the difference varies, however, from one material to another. To gain an understanding of the relationship between these two measure of strength, we have carried out an analysis of bending which accounts for the deviations from ...

Effect of Fiber Orientation and Fiber Contents on the Tensile Strength in Fiber-Reinforced Composites

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.

Fiber strength and fiber/matrix bond strength in single crystal Al2O3 fiber reinforced Ni3Al based composites

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.

Strength of Fiber-Reinforced Concrete

Journal of the Structural Division, 1972
The results of experimental and analytical studies on the characteristics of concrete reinforced with uniformly distributed short wire pieces are presented. The experimental program includes tests on workability, modulus of rupture strength, and compressive strength of 75 batches of concrete; the major variables are water-cement ratio, percentage of ...

High strength electrospun fibers

Polymers for Advanced Technologies, 2011
AbstractElectrospinning provides a simple method to process solutions or melts, mainly of polymers, into continuous ultrathin fibers. However, the mechanical properties of electrospun fibers are low due to non‐optimized macromolecular orientation in the fibers. The methods of CNT reinforcement and heat‐induced orientation of rigid macromolecular chains

Fiber With High Tensile Strength

SPIE Proceedings, 1986
Glass as the optical fibre material is very sensitive to the damaging effect of flaws. Fracture mechanics theory shows up this influence and gives the possibility of predicting fiber strength in long-length application and time-to-failure based on examinations of short samples.

Tensile Strength of Fiber-Reinforced Composites: III. Beyond the Traditional Weibull Model for Fiber Strengths

Journal of Composite Materials, 2000
Commercially available graphite and ceramic fibers exhibit statistical strength distributions having separate Weibull moduli p' for the scaling of strength versus fiber length and p for the distribution of strengths across a collection of fibers at fixed length.

The Strength and Weakness of Cotton Fibers

Textile Research Journal, 1951
The 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.
