They control the vibrational behaviour of composite structures and are also an ideal tool for monitoring of the development of ...
A universal correction factor of 0.925 resolved the non-uniformity involved in the V-notched rail shear test. This enabled the in-plane shear modulus of unidirectional carbon fiber- or glass fiber-reinforced composites to be accurately determined....
Values of G12 were found to be approximately proportional to the shear modulus Gm of matrix material but were about 30% lower than predicted by the theory of Hashin and Rosen. The anisotropy of the carbon filaments and voids in the composite samples were proposed to account for the ...
Specimens of the material (carbon fiber/phenolic resin composite) were subjected to heat treatment at 500, 1,000, 1,500 and 2,000°C, and measurements of shear strength and shear modulus were performed using the Iosipescu mode. Experimental data were compared with the results obtained ...
The main aim of the present work was the determination of the shear modulus (G12) and the maximum shear strength (ô12) using the Iosipescu Shear Test. Tests were carried out on two types of composites, carbon fiber/epoxy and glass fiber/epoxy, used in the aerospace industry, and ...
That allows you to define the "area" of the beam and the "modulus" of the beam as separate values as required by many programs. Another comment: I am guessing that the stiffness of the foam is much less than the stiffness of the carbon fiber shell. In that case, the main thing that...
The decrease in ultimate tensile strength, shear strength, tensile modulus, and shear modulus of fiber reinforced composites exposed to fire or to high temperature was investigated. A simple model was developed for calculating the mass loss of the material and the thickness of the char layer. The...
BASED ON NUMEROUS TESTS ON A SPECTRUM OF DISTURBED AND UNDISTURBED SOILS, THE SHEAR MODULUS DECREASES AND THE DAMPING RATIO INCREASES VERY RAPIDLY WITH INCREASING STRAIN AMPLITUDE. THE RATE OF INCREASE OR DECREASE DEPENDS ON MANY PARAMETERS: EFFECTIVE MEAN PRINCIPAL STRESS; DEGREE OF SATURATION; VOID...
1.02.6.1.1 Modulus (i) Experimental The axial modulus of carbon fibers is simple in principle to measure. The difficulties are that the fibers have small diameters and only require small loads for mechanical loading. The fiber cross-section is the largest error in the modulus determination, and...
