This study investigated the effects of high temperature exposure on the compressive, tensile, and flexural strengths of concrete containing glass fiber. A total of 108 cubic specimens (150 mm × 150 mm × 150 mm), cylindrical specimens (300 mm × 150 mm), and prismatic specimens (500 mm × 150 mm × 150 mm) were prepared for compressive, tensile, and flexural strength testing, respectively. The spec...

Continuous glass fiber polymer–matrix composites are electrically insulating and used for printed wiring boards, but their thermal conductivity needs to be increased without sacrificing the electrical insulation ability. The through-thickness thermal conductivity of these epoxy–matrix composite laminates with in-plane fibers is found to be effectively modeled using the Rule of Mixtures with fib...

Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. In another study the effect of wavelength on the phase variatio...

the value of the permeability in fluid flow through porous media is important for process investigation. in low reynolds number, the classic darcy’s law is suitable for simulation of fluid flow. in this paper, an experimental study for evaluation of preformed fiber permeability has been done. also, the deviations from the classical darcy law by experimental and numerical simulation of the navie...

This paper studies the compressive failure behavior of pw-GFRP (plain-woven glass fiber reinforced polymer) sandwich composite L-joints for ships. Six L-joint specimens were subjected to ultimate tests, which show that damage and stiffness degradation started much earlier than any visible signs. A modified kinking criterion is developed layup structure. Moreover, a hybrid model applied simulate...

In the perspective of environmental advance, significant attentiveness is being displayed in usage natural fibers like reinforcement polymer composites. This paper focuses on building a prosthetic socket arranged from fiber-reinforced composite as an effort to substitute material currently accessible manufacturing socket. The vacuum bagging procedure was adopted yield below-knee laminates encom...

in the present research work, the flexural modulus and strength of glass fiber-epoxy resin and carbon fiber-epoxy resin composites have been enhanced through fiber tension during curing of the polymeric resin. this study showed that the tension applied on the fibers increased the flexural modulus of the glass-epoxy composites up to 12% and the flexural strength up to 19%. the flexural modulus a...
