Buckling of fibers in fiber-reinforced composites

Composites Part B: Engineering, 2012
Abstract Elastic stability of fibers in fiber-reinforced composite materials subject to compressive loading is studied. The transversal buckling mode is considered, and two limiting cases, the dilute and non-dilute composites are analyzed. In the case of a non-dilute composite, the cylindrical model and the lubrication approximation are applied.

The Elastic Moduli of a Fiber-Reinforced Composite

Journal of Applied Mechanics, 1977
A composite consisting of a homogeneous isotropic elastic matrix containing infinitely long parallel circular cylinders is considered. The cylindrical fibers have identical physical properties and are firmly bonded to the matrix with uniform spatial distribution. Only plane problems are considered.

Reinforcing Fibers for Composites

1993
The paper focuses on carbon fibers including carbon fiber preparation, the physical properties of carbon fibers, functional groups present on carbon fiber surfaces and the relationship of surface chemistry to composite properties. Specific topics include thermal treatment of PAN-based carbon fibers, carbon fiber structure, tensile breaking strength and

MODELLING FIBERS IN FIBER-REINFORCED COMPOSITES [PDF]

, 2017
In this work we present a concept for modelling fibers in fiber- reinforced composites, such as fiber- reinforced concrete (FRC). This heterogeneous material is composed of different constituents which exhibit complex behaviour. In the first part of the work, the numerical model is described, and in the second part experimental results for bond-slip ...

Fungal Degradation of Fiber-Reinforced Composite Materials

CORROSION 1996, 1996
Abstract We described in a previous report that a fungal consortium isolated from degraded polymeric materials was capable of growth on pre-sterilized coupons of five composites, resulting in deep penetration into the interior of all materials within 5 weeks.1 Data describing the utilization of composite constituents as nutrients for the

The Fiber-Reinforced Composite

1975
Exact elastodynamic solutions within the context of classical elasticity theory are not available for fiber-reinforced composites. It is, however, to be expected that qualitatively a difference analogous to the one observed in laminated solids, should exist for dispersion of waves propagating in the direction of the fibers, and normal to the fiber ...

Extruded Fiber-Reinforced Composite

2002
Publisher Summary High performance fiber-reinforced cementitious composites (HPFRCC) exhibit increased tensile strength, enhanced toughness, and sometimes, a strain-hardening response. The amount of fiber reinforcement needed to achieve this behavior is higher than what can typically be added to conventional cast-in-place concrete.

Fiber reinforced composites orthodontic retainers.

Minerva stomatologica, 2015
Retention is the phase of orthodontic treatment that attempts to hold teeth in their corrected positions after orthodontic therapy is completed. The aim of this study was to consider fiber-reinforced composites (FRC) as a possible alternative to conventional multistranded stainless steel wire for retention through SEM analysis.Two different FRC ...

Thermoplastic composites reinforced with keratin fibers

2011
In this work, composite materials based on wool fibers, raw or chemically modified, and thermoplastic matrices, either polyolefins or biodegradable polyesters, were prepared and thoroughly characterized in terms of morphology, thermal properties and mechanical performances.
