Optimal Design of FRP Taper Spring Using Response Surface Analysis
Composites Research, volume 17, issue 2, 2004, Pages 1~8
The present paper is concerned with the optimum design of taper spring, in which the static spring rate of the fiber-reinforcement composite material spring is fitted to that of the steel leaf spring. The thickness and width of springs were selected as design variables. The object functions of the regression model were obtained through the analysis with a common analytic program. After regression coefficients were calculated to get functions of the regression model, optimal solutions were calculated with DOT. E-glass/epoxy and carbon/epoxy were used as fiber reinforcement materials in the design, which were compared and analyzed with the steel leaf spring. The result of the static spring rates show that optimized composite leaf springs agree with steel leaf spring within 1%.
An Analytical Investigation on the Flexural Behavior of FRP Reinforced Concrete Slab by Orthotropic Plate Theory
Composites Research, volume 17, issue 2, 2004, Pages 9~14
In this study, analytical investigations on the flexural behavior of FRP reinforced concrete slab were discussed. In the derivation of analytic solution, the FRP reinforced concrete slab was modeled as a structural orthotropic plate. To determine the flexural rigidities of an orthotropic plate model, the elastic equivalence method was employed. In the finite element analysis, the approximate method to determine the rigidity matrix of orthotropic plate element was also suggested using the elastic equivalence method. The results obtained by the analytical solution and the finite element analysis were compared with that of experiment.
Study on Evaluation of Carbon Fiber Reinforced Composite Groove Using Inverse Ballistics Technology
Composites Research, volume 17, issue 2, 2004, Pages 15~20
It is a primary object of the present study to test and evaluate the shear load carrying capability of a carbon fiber reinforced thermoses composite structure with buttress grooves for military applications. The buttress form of groove is an effective structure in any applications where high shear loads are transferred in one direction between structural components. Inverse ballistics methodology was introduced to investigate the high strain rate properties of composite groove specimens. In comparison with the conventional methods, inverse ballistics technique is a proper one under dynamic environment
A study on the manufacture of polymer concrete using the waste paint
Composites Research, volume 17, issue 2, 2004, Pages 21~27
In this paper, the polymer concrete using the chemically treated waste paint and polystyrene foam was manufactured and their mechanical properties were evaluated. The compressive strength, specific gravity and water absorption with respect to the volume percents of the waste paint and resin were tested. From the tests, the specific gravities of the polymer concretes using the waste paint were lower than that of the conventional polymer concrete and it was recommended that they can be used for building exterior materials.
Failure detection of composite structures using a fiber Bragg grating sensor
Composites Research, volume 17, issue 2, 2004, Pages 28~33
Failure detection in a cross-ply laminated composite beam under tensile loading were performed using a fiber Bragg grating (FBG) sensor. A Passive Mach-Zehnder interferometric demodulator was proposed to enhance sensitivity and bandwidth. The proposed FBG sensor system without active device such as a phase modulator is very simple in configuration, easy to implement and enables the measurement of high-frequency vibration with low strain amplitude such as impact or failure signal. Failure signals detected by a FBG sensor had offset value corresponding to the strain shift with vibration at a maximum frequency of several hundreds of kilohertz. at the instant of transverse crack propagation in the 90 degree layer of composite beam.
Tensile Behaviour of Foamed Metal Matrix Composite Using Stochastic FE Model
Composites Research, volume 17, issue 2, 2004, Pages 34~39
In this paper, a modified and representative unit cell model was employed to study the tensile behaviour of closed-cell metallic foams with varying spatial density distribution as well as material imperfections. The density variation was assumed to follow a statistical probability distribution of the Gaussian type. A multiple cell finite element model, utilising the modified unit cell, was developed. The model exhibits deformation patterns similar to those observed in tensile testing. The nominal stress-strain curve obtained from quasistatic tensile of the foam was compared with experimental findings and was found to be in good agreement in the scheme of maximum strength only if the appropriate density distribution and volume fraction of internal imperfections are taken into account. Moreover, maximum tensile strength of the aluminium foam was found to be more sensitive to the volume fraction of imperfection than standard deviation of the density.

Nomaguchi, Kanemasa ; Forsdyke, Ken L. ; Brown, Denver E. ;
Composites Research, volume 17, issue 2, 2004, Pages 41~48
"Phenolic composite", one of safety composites was chosen to build rolling stock in England while it was applied to building materials in London Underground facilities. This paper was written by Mr. Denver E. Brown. He emphasizes, from visibility and toxicity points of view, phenolic is the best and Mr. Forsdyke says, there is no question, passenger's lives are No. 1 issue, material recycling is not No.1! not No.1!
