PROJECTS

We are constantly engaged in a number of interesting projects. We are a small company, but our study topics have wide-ranging implications. We are grateful for our clients who challenge us with various exciting projects.

Energy and Environmental Studies
 

Energy is a global business, and as such, everything and everyone involved in energy resource extraction, transportation, distribution, and end-use are interconnected. We have been studying the impacts of national energy and environmental policies on global energy trade and identified unintended consequences of strict ecological protection that cause an increase in greenhouse gas emissions on a global scale.

Underground Infrastructure Analysis

 

Since the days of Thomas Edison and George Westinghouse, the use of electricity and industrialization of a nation created a synergistic effect. Now, we only think of such essential services as light, water, and clean toilets when these utilities fail. Unfortunately, many of our utilities were buried underground and difficult to access, making it almost impossible to assess the well-being of the critical utility network. We have developed a tool to evaluate these “hard-to-access” facilities and provide repair and upgrade advice to our customers before they fail.

Aerospace and International Trade

 

As energy and environmental science have a global implication, the growth of the aerospace industry has brought nations and peoples closer together. We have been studying the growth of this industry and development of global supply chains to support aircraft and satellite production. We got into this business from the energy side as airplanes, satellites, and airports have their own special energy needs. Having cultivated a network of clients in the aerospace industry, we have been creating beneficial business partnerships and advising gaps in parts supply-and-demand to identify niche markets for small businesses.

 

Carbon Composite Research

 

Infra Innovations is involved in a research and development program to create a new way to improve repair methods for thermoset carbon composites in aerospace applications. As carbon fiber reinforced plastics (CFRP) are gaining wide acceptance, it is becoming more and more important to develop fast and efficient repair techniques for structures made of such materials. In our development, we addressed the issues surrounding CFRP repair methods, such as: (1) reduction of heating time, (2) reduction of curing time, (3) more precise control of temperature, location, and heating time for thermal curing, and (4) a conceptual design of a robotic system to assist repair technicians to assure uniform quality and to facilitate automation.  The pictures on the right show the result of our heating method.  The CFRP workpiece was heated to 120℃ in 120 seconds in both pictures.  The image on the top shows hotspots that are typical when a single heat source is used.  The picture on the bottom shows a more uniform temperature distribution just by tweaking a little with our method, indicating that precise temperature control is possible.

 

We can heat workpieces of complicated shapes and curvatures precisely with our heating method. We can even heat the carbon surfaces only and accommodate either lower or higher temperature bands in the precise form of metal parts that might need to be bonded to the CFRP piece. For example, this method can be employed to bond CFRP to metal spars and stringers in aircraft structural parts. Also, other areas of application will be to heat and cure curved materials, such as radar domes, nose cones, etc. However, thermal curing and uniform bonding along curved surfaces may pose technical challenges.
