Effect of Fatigue Damage in Woven Composites on Thermo-Mechanical Properties and Residual Compressive Strength

Journal of Composite Materials, 1996
The long term mechanical and thermal fatigue of a Celion G30-500/PMR-15 woven composite system is investigated to study the interrelationship between thermo-mechanical properties, namely the thermal expansion coefficent (TEC) and the compressive strength.

Mechanical property optimisation of materials by nanostructuring: reduction of residual compressive stress in ta-C film

Materials Science and Technology, 2004
Abstract Optimisation of the mechanical properties of a tetrahedral amorphous carbon (ta-C) thin film was attempted by nanostructuring. In this study, nanoscale multilayer films of ta-C and Si incorporated ta-C:Si layers were prepared. The residual compressive stress of the multilayer films decreased drastically without a decrease in the hardness and ...

Post‐fire behavior of steel slag fine aggregate concrete

Structural Concrete, 2022
Using steel slag fine aggregate (SSFA) to replace river sand (RS) in making concrete offers a sustainable solution for mitigating the environmental issues owing to the large‐scale mining of RS and disposal of a large amount of steel slag.

Compressibility factors, densities, and residual thermodynamic properties for methane-water mixtures

Journal of Chemical & Engineering Data, 1989
Smoothed compressibility factors and residual thermodynamic properties for mixtures of 50, 25, and 10 mol% water vapor in methane are presented along with experimental densities. Pressure-enthalpy diagrams for the three mixtures are also provided. The measured densities cover a temperature range of 498.15-398.15{Kappa} and a pressure range of 72 kPa to

Residual stresses and properties of epoxy-polymers in tension and compression

Mechanics of Composite Materials, 1986
1. A procedural approach was developed for studying residual stresses and their effect on the physicomechanical properties of stiff epoxy binders. 2. The formation of residual stresses in the polymer block leads to a regular distribution of the percentage of free volume and the nonrandom formation of defects. 3. Tensile tests

Post-impact residual high strain rate compressive properties of carbon fiber laminates

Journal of Reinforced Plastics and Composites, 2013
The purpose of the present study is to investigate the residual high strain rate compressive properties of cross-ply carbon fiber laminates after drop-weight impact. The tested laminate is divided into four quadrants and specimens are extracted from each quadrant for high strain rate compression testing using a split–Hopkinson pressure bar.

Cold compression deformation method for reducing residual stress and uniformizing micro-property in ferrite steel

Journal of Iron and Steel Research International, 2021
To reduce internal residual stress and homogenize micro-property of hot-rolled ferrite steel, the cold compression deformation method with small reduction rate has been performed in the hot-rolled samples, and X-ray diffraction and nanoindentation test have been used to detect the residual stress and micro-property. The samples with deformation rate of
