Mapping water uptake in an epoxy-phenolic coating

Modelling Cyclic Moisture Uptake in an Epoxy Adhesive

This paper presents a methodology for predicting moisture concentration in an epoxy adhesive under cyclic moisture absorption-desorption conditions. The diffusion characteristics of the adhesive were determined by gravimetric experiments under cyclic moisture conditions and the dependence of diffusion coefficient and saturated mass uptake on moisture history was determined. Non-Fickian moisture...

Development of Coating Thickness Instrument for Graphite/epoxy Composites

The ability to measure the thickness of paint on graphite/epoxy composite structures directly would be of benefit in the aerospace industry. The weight reduction would increase fuel mileage for the airline customer. An additional reason for reducing the thickness of paint on graphite/epoxy composites is not as obvious as the weight savings. A concern in the use of composite structures has been ...

Applications of FTIR on Epoxy Resins – Identification, Monitoring the Curing Process, Phase Separation and Water Uptake

Wear resistant solid lubricant coating made from PTFE and epoxy

A composite coating of polytetrafluoroethylene and epoxy shows 100 · improvements in wear resistance as compared to either of its constituents alone and reduced friction coefficient under testing on a pin-on-disk tribometer. This coating is made by impregnating an expanded PTFE film with epoxy, which provides three unique functions: (1) the epoxy compartmentalizes the PTFE nodes, which is belie...
