ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. Cyclic thermal loading reveals a complex dependence of the physicomechanical properties of fabric glass laminate on the number of cycles. At temperatures of up to 400°C the main changes in the state of the material, reflected in its strength, occur in the first two heating cycles. 2. For stress analysis of structures made of polymer-based composite materials and operating under conditions of repeated thermal loading, the results obtained after a single heating cannot be used. To obtain a more accurate picture of the strength potential of such materials, their physicomechanical properties have to be investigated by modeling the operating conditions of the structure (number of cycles, cycle temperature, heating rate, etc.). 3. In assessing the effect of the repetition of thermal loading on the physicomechanical properties of composite polymer materials, their properties should be evaluated both at normal temperatures between cycles and at the cycle temperatures, so as to obtain the minimum values of the investigated properties (strength, modulus of elasticity). 4. Up to 400°C and ten thermal loading cycles the investigated material retains sufficient strength (up to 40% of the initial value), and it may therefore be recommended for use under corresponding thermal loading.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusion 1. The strength and elastic characteristics of fiberglass laminate with a silicone binder were determined and the rules of their change under single and repeated temperature action were established. 2. It was shown that in tension and compression in the 77–400 K temperature range fracture of the material occurs both as the result of development of microcracks existing in the original structure of the material and preferentially oriented in planes perpendicular to the plane of the reinforcing fabric and as the result of development of defects at the interface of the components in the planes of reinforcing. 3. It was established that with a reduction in temperature the contribution to the fracture process of defects (cracks) developing at the interface of the components increases, as the result of which under low temperature conditions fracture of the material both in tension and in compression is initiated by separation of it.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. Expressions have been obtained for transforming the temperature deformation coefficients under a rotation of axes. 2. It has been shown that for orthotropic materials the generalized Hooke's law expressions written in the principal axes of elastic symmetry (1) do not contain the shear coefficient of temperature deformation; these coefficients do however appear if the coordinate axes are rotated. 3. It has been shown that the graphical construction of the expressions for the transformation of the temperature coefficients is similar to that for the transformation of components of the stress or strain tensors. 4. The curve for the shear coefficient of the temperature deformation takes the particular form of a Cassini oval (lemniscate) which is symmetrical about a straight line making an angle of 45° with the elastic symmetry axes.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. Asbotextolite VTU UKh P 183-60 has a considerable anisotropy of its thermal strains along the axes of elastic symmetry; this must be taken into account when designing structural elements of these materials. Glass Textolite SSFT has a more equally balanced arrangement of the fabric pattern and a more uniform distribution of its filaments with respect to direction; it accordingly has a lower anisotropy of its thermal strains. 2. There are considerable differences between the quantitative estimates of the thermal strains in these materials determined by means of rod and disk samples, respectively, especially in the directions deviating from the axes of elastic symmetry. 3. The method of measuring thermal strains on round (disk) samples may be recommended as more correct, since it eliminates the effects of the severed filaments and also enables shear strains to be measured. 4. A study of the shrinkage of Asbotextolite shows that the latter possesses shrinkage anisotropy of the same character as the anisotropy of the thermal strains. In addition to this, the shrinkage of Asbotextolite is closely related to the loss of weight by this material.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. The character of the change in the mechanical characteristics of carbon-metal-plastics with heating was shown. It was noted that strength and elastic modulus change more rapidly in compression and bending than in tension. 2. Strain-hardening of carbon-plastic and carbon-metal-plastic was observed in compression within the temperature interval 200–400 °C. 3. It was demonstrated that it is possible to approximate the stress-strain diagram of orthotropic materials with an equation of the form ɛ = σ/E [ 1 + k/n (σ/σp. 1.) n−1], the applicability of which was confirmed by the empirical data.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. The investigated materials possess significant anisotropy of mechanical properties in tension and bending and insignificant in compression. With an increase in temperature the parameters of anisotropy increase, especially in carbon and carbon-metal plastics. 2. The relationships of tensile strength and modulus of elasticity of the studied materials to the angle of the test α have the form of steadily dropping curves which with an increase in temperature do not change substantially.Type of Medium: Electronic ResourceURL: -

The rules of the change in the supporting capacity, strength, and degree of damage of carbon composite materials with a ceramic matrix were determined in relation to the time of action of the high temperature oxidizing atmosphere. 2. It was established that oxidation of such materials starts from the fibers of the carbon filler and there is a linear relationship between the thickness of the oxidized layer and heating time. 3. A relationship was proposed for describing the change in strength of the investigated carbon composites in relation to the time of action of the high temperature oxidizing atmosphere based on the experimentally established rules of the degree of damage of materials, which in the case of bend tests may be satisfactorily described by a second power polynomial relative to the thickness of the layer of material damaged by oxidation.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. It has been established that the strength of CRP is most affected by the type of filler in the temperature range 293–1000°K with tension, and least affected with compression. Whereas the maximum amplitude between the greatest and least values of relative strength for CRP with compression is a little more than 20%, with tension it is 50%. 2. Reinforcement of CRP by different types of filler in the test temperature range also has a marked effect on their elasticity properties. For example, under tensile conditions at 873°K the elasticity modulus of CRP reinforced with TMP-4 fabric is maintained at 80% of the initial value, whereas the elasticity modulus for CRP reinforced with carbon knitted cloth with a pyrocarbon coating is only retained at 10%.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The article established the regularities of change of the physicomechanical characteristics and strength of glass textolites in single and repeated thermal loading. It shows that under multiple loading the intense loss of strength of the investigated materials is due to increased porosity on account of the large number of microcracks appearing in the structure. A correlation is obtained between the elastic and strength characteristics and porosity in dependence on the temperature of multiple heating which in the first approximation is described by a polynomial of second degree with respect to temperature, multiplied by the reciprocal of porosity.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9325Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Conclusions 1. The deflection is a linear function of the load within the elastic region with free support (Fig. 1a) and with free edges (Fig. 1b). 2. The deflection is a function of the angle from the principal axes (Fig. 3) in a circular plate having cartesian orthotropy and subject to an axially symmetrical load. 3. The deflection of a circular orthotropic plate along the principal axes of anisotropy is very sensitive not only to the thicknesses and relation between the layers but also to the reinforcement direction, not only in the case of free hinging (Fig. 2, fiber ratio 1:2) but also with free edges (Fig. 3), except in the direction π=45°. 4. The rigidity of the plate varies with the angle from the principal axes along a convex curve, whose maximum lies at π=90°, which corresponds to the layer direction with a fiber ratio of 2 (Fig. 3).Type of Medium: Electronic ResourceURL:
