Australia's place in the world
Australia ranks 5th for research impact in this technology with Swinburne University of Technology ranked 7th globally. China has the highest research impact in this area and also has 3 institutions in the top 10 internationally—including the top institution, the Chinese Academy of Sciences—and the United States is second. Eight of Australia’s research institutions are ranked in the top 50 internationally.
Germany has the highest venture capital (VC) investment ahead of the United States, while Australia is unranked. Internationally, VC investment has been decreasing by around 5% p.a. since 2016. Globally, the number of patents has been steady since 2015.
Given the sensitive nature of this technology much cutting-edge research is unlikely to be in the public domain, meaning this assessment may not be a true reflection of overall research capability. This assumption is also supported by the limited patent activity in this area. China has the greatest number of patents, more than triple that of 2nd ranked United States; Australia is ranked 18th.
Opportunities and risks
Advanced composite materials are an example of a niche, high‑technology, high value-add form of manufacturing with a range of applications, and which also enable many other critical technologies. The Australian composites market was valued at $480 million in 2020, and is expected to grow to over $10 billion by the end of 2030. These materials may prove important for Australia’s defence capabilities in aerospace and other operational requirements in equipment and vehicles. The importance of these materials is highlighted by their inclusion in each of the 2, 5 and 10 year success measures for research & development in the Space National Manufacturing Priority road map. Advanced composite materials are quickly becoming an important part of the clean energy and manufacturing sectors, and will play a role in energy transition; for example, new wind turbine blades, materials to reduce the weight of advanced vehicles and more efficient hydrogen storage.
Advanced composite materials are not without their drawbacks. Some materials require high levels of investment and expertise to produce. For example, Borophene—which can be used in next generation electronic devices, superior battery electrodes and safer hydrogen storage capabilities—is difficult and expensive to produce. Metal organic frameworks—which can be used in gas masks and removal of low‑concentration gases in confined spaces—have issues with their stability, working capacity and scalability. Ongoing investment and effort is required to develop efficient and cost-effective production methods for these materials is essential in order to realise their potential benefits.
Applications for advanced composite materials can be very diverse and go beyond the original use they were designed for; this is often not obvious to inventors or manufacturers. These materials thus represent a potential espionage target, especially given their enabling capabilities for various military and security applications. Given Australia’s relative strength in this area, it is a risk that must be carefully managed.
Research impact (RI)
China has the highest research impact in this area, ahead of the United States. Australia is ranked 5th. Total volume of published research has been increasing at 7% p.a. over the 5 year period 2016–2020, with 21% of research involving international collaboration.
- China - 2301
- USA - 1708
- India - 806
- UK - 454

The research impact provides an indication of the productivity of a country or institution. Here, productivity was assumed to be represented by the volume of publications (i.e. scholarly output) as an indicator of the resources & facilities, and the level of interest in the publications as an indicator of quality.
Germany has the highest amount of VC investment in advanced composite materials, ahead of the United States and China. Globally, investment in this area has been declining at around 5% p.a. since 2016. Australia is unranked.
