Study Test

In this study, test specimens of nanocomposites were produced through Vacuum Assisted Resin Transfer Molding process, VARTM. By using Epoxy as substrate, test specimens of Nanocomposites were prepared as multiple layers of carbon fibers, clay and carbon nanotube. The carbon fibers are featured in high strength and high thermal conductive. Also, the clay and the carbon nanotube have outstanding nature of strength.To explore the hardness, stress, strain and friction of nanocomposites, various experiments were used in this study, including mechanical hardness test, tensile test and pin on disc bench test. With optimized amount of additives, physical properties of the material, including hardness, tensile strength have increased by 94 % and 111 %. Dry friction is also decreased with the increase of mechanical properties.

Reinforced Plastic

Carbon fiber reinforced plastic (CFRP) is a composite material in which carbon fibers are impregnated with resin to achieve both high strength and high rigidity. CFRP is an excellent material, but it is expensive in terms of materials, manufacturing costs, and capital investment, and it takes a lot of time to complete a product. In order to solve these problems, the demand for de-autoclaving has been increasing in recent years. If molding can be performed without autoclaving, it will be possible to reduce costs and improve productivity in terms of materials and capital investment costs.

Temperature And Humidity

The monitoring of structures is one of the most difficult challenges of engineering in the 21st century. As a result of changes in conditions of use, as well as design errors, many building structures require strengthening. This article presents research on the development of an externally strengthening carbon-fiber textile with a self-sensing option, which is an idea is based on the pattern of resistive strain gauges, where thread is presented in the form of zig-zagging parallel lines. The first laboratory tests showed the system’s high efficiency in the measurement of strains, but also revealed its sensitivity to environmental conditions. This article also presents studies on the influence of temperature and humidity on the measurement, and to separate the two effects, resistance changes were tested on unloaded concrete and wooden samples. The models were then placed in a climatic chamber, and the daily cycle of temperature and humidity changes was simulated. The research results confirmed preliminary observations of resistivity growths along with temperature. This effect is more visible on concrete samples, presumably due to its greater amount of natural humidity. The strain measurement with carbon fibers is very sensitive to temperature changes, and applications of this method in practice require compensation.

AbstractThermal-stable, conductive, and flexible carbon fabric (CF), which is composed of thin carbon fibers prepared by electrospinning, was used for the substrate of carbon nanotube (CNT) field emitter arrays. The field emitter arrays were prepared by chemical vapor deposition (CVD). The current density-electric field characteristics revealed that the CNT field emitter arrays on CF produced a higher current density at a lower turn-on voltage compared to ones on a Si substrate. This emitter integrated with a gate electrode based on hierarchy-structured carbon materials, CNTs on CF, can be used for light sources, displays, and other electronic devices.
