Eddy Current Examination of Carbon Fibres in Carbon-epoxy Composites and Kevlar
This paper proposes a special eddy current transducer, send receive type and a holographic method for signal processing, able to emphasize the delaminations and massive breaking zones in carbon fibres. To evaluate individual fibres breaking, a eddy current microscopy method is proposed.
متن کاملThermal Problems in Hyperbaric Environments
This paper reviews thermal problems in hyperbaric environments and provides information how to estimate thermal comfort zones in hyperbaric environments. Divers are exposed to hyperbaric helium-oxygen atmospheres when engaged in saturation diving operations. However, some difficulties to control thermal environments arise from the extremely high thermal conductivity of helium used as a breathin...
متن کاملThermal analysis of fibres and films in solvents and vapours
The thermomechanical and dynamic mechanical properties of films and fibres in vapour laden atmospheres and simulated dye baths were investigated in order to understand their processing behaviour. Acetone and water vapour acted as plasticisers for cellulose acetate film. 2-phenoxyethanol was found to penetrate poly(ethylene terephthalate) film above its glass transition temperature and consequen...
متن کاملSpace Environment Characterisation of Kevlar
Kevlar® is a material extensively used for the design and manufacturing of the shields protecting the manned elements of the International Space Station (ISS) from the threat posed by meteoroids and space debris that increasingly pollute the Earth orbits. Kevlar has been also selected for extensive use in the manufacturing of innovative flexible structures under development for future manned ex...
متن کاملsuppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
