A 3D shear-lag model considering micro-damage and statistical strength prediction of unidirectional fiber-reinforced composites

A new numerical model is proposed for simulating the mechanical behavior of unidirectional composites which is based on a three-dimensional (3D) shear-lag model. The 3D shear-lag model considers the micro-damage phenomena of interfacial debonding and inter ...

Three-phase nitrobenzene hydrogenation over supported glass fiber catalysts: reaction kinetics study

Albert Renken, Lioubov Kiwi, Volker Höller, Dagmar Wegricht

The catalytic properties of Pd and Pt supported on woven glass fibers (GF) were investigated in the three-phase hydrogenation of nitrobenzene (NB). Over all catalysts, a 100% yield of aniline was attained. The catalytic activity for the best catalysts was ...

Tensile strength of fiber-reinforced composites: II. Application to polymer matrix composites

William Curtin

An analytic model for predicting the tensile strength of uniaxial fiber-reinforced composites is applied to several different graphite-fiber composites and shows good agreement with measured strengths. The model includes the effects of fiber statistical st ...

Kinetic undercooling in solidification of a hypereutectic Al-Si alloy; Effect of solidifying within a ceramic preform composite

Andreas Mortensen

Dendrite tip temperature measurements are reported for the hypereutectic alloy Al-30% Si, directionally solidified as a bulk (non-composite) alloy, and also as the matrix of a fibrous metal matrix composite. Over the range of tip velocities studied (10-100 ...

Fracture and Interface Properties of a Composite with Long Aligned Fibers

John Botsis

Results on fracture, fatigue crack growth and debonding on compact tension specimens of a specially made composite material are reported. The specimens consisted of an epoxy matrix and layers of equally spaced long aligned glass fibers. The experimental da ...

STRENGTH DISTRIBUTION OF CARBORUNDUM POLYCRYSTALLINE SIC FIBERS AS DERIVED FROM THE SINGLE-FIBER-COMPOSITE TEST

William Curtin

The single-fibre-composite (s.f.c) test, in which a fibre is embedded in an epoxy matrix and the composite tested in tension, was employed to obtain the statistical strength distribution of Carborundum SiC ceramic fibres over the range of gauge lengths fro ...

EXACT THEORY OF FIBER FRAGMENTATION IN A SINGLE-FILAMENT COMPOSITE

William Curtin

An exact theory is developed to describe the evolution of fibre fragmentation in a single-filament composite test as a function of the underlying fibre statistical strength and fibre/matrix interfacial shear stress, tau. The fragment distribution is a comp ...

FIBER FRAGMENTATION IN A SINGLE-FILAMENT COMPOSITE

William Curtin

The fiber fragment distribution obtained from tensile testing of a single-filament composite contains vital information on the in situ strength of the fiber at short gauge lengths and on the shear stress across the fiber/matrix interface. Here, this fragme ...
