High Temperature Coatings for Composites
Abstract
With state-of-the-art capabilities and a proven track record in supplying advanced coating solutions for industry, Swinburne Univers ity of Technology (SUT) will carry out an accelerated R&D program to develop a new generation of protective coatings for carbon fibr e reinforced composites. This will be executed in partnership with ONR stakeholders so that this new functional coating solution wil l address the needs for improved thermal protection and appropriate mechanical properties; while maintaining the production cost at an acceptable level. To achieve the objectives of the project, industrially accepted coating methods such as thermal and cold spray technologies will be employed. In particular, thermal spray processes use a high temperature flame jet that melts and accelerate pow ders towards the chosen substrate, whilst the contemporary coating process is cold spray that employs a supersonic gas jet to form a coating by impingement of particles at a threshold velocity onto a solid surface. Processing using these spray technologies enables the flexible fabrication of multilayered-functional coatings with each layer possessing the desired characteristics such as high ad hesion bond strength or low thermal conductivity. SUT has proprietary knowledge of fabricating such coating-substrate combinations f or high temperature applications.In this project, ONR will be able to leverage SUTs dedicated coating facilities located in Melbour ne, Australia, and will jointly work with SUT researchers on high temperature coating development for their choice of composite subs trate. Apart from coating development, SUT will contribute its current know-how and access to specialist kit to validate key thermal performance characteristics of the coated product, as well as benchmarking against baseline materials.
