Ever since Skynet unleashed a few Terminators, robots in general have been stereotyped as unfeeling metallic brutes. Recently however, we have started to see the softer side of robots. I don't mean humanoid-looking robots like Sophia, the first robot to gain citizenship from a country. I am referring to the new field of Soft Robotics, which produces machines more physically sensitive to humans and the world around them.

Advances in Soft Robotics are taking many forms. Some engineers are designing soft robots that mimic living organism’s ability to move through our complex physical world. Other designers are focusing on enabling robots to better interact with humans and other living things. Both soft paths however are based on using new compliant materials, made of innovative combinations of polymers, elastomers, polyurethanes, as well as composite materials.

Many markets have benefited from the advance of composites, but perhaps none more so than the Recreational and Commercial Marine industries. Building vessels that can meet the exacting demands of a water environment, especially a saltwater one, has always been a challenge. Life at sea means continual exposure to harsh elements - including direct sunlight, wind and water pressure, the corrosive effect of saltwater, as well as man-made factors such as diesel fuel, lubricants, and other chemicals.

Composites provide some of the best solutions to issues caused by these marine conditions. From stronger FRP (fiber-reinforced polymer) boat hulls and interiors, to corrosion-resistant marine parts, to specialized submersible components, marine composites have revolutionized what is possible. 

Composites are changing the world we live in. From the Stone Age, to the Bronze Age, to the Iron Age, our civilization’s history has been defined by the materials we use. In the past, humans reshaped the raw materials they discovered in nature to create the items they needed. In our modern age we have moved beyond found objects, and have developed the technology to produce new materials, whose very make up is engineered specifically to fit the task at hand.

Damaged and worn out metal components and assemblies are a major cause of downtime for businesses. However, it’s usually too expensive to replace an entire system with the latest model. The solution may be switching to composite replacement parts, which deliver a cost-effective way to increase the operational performance of existing systems.

By rebuilding your existing components and assemblies using composites, modern technology has the capability to make your parts better than they were before. Better... stronger... faster.

One of the most dynamic and creative technologies in recent years is Additive Manufacturing, often referred to as "3D Printing". The amazing ability to create solid objects from digital files stored on a computer, was only recently considered pure science fiction. Having a magic box that could manufacture items out of thin air became a familiar concept on shows like Star Trek, where a “Replicator” could produce any item their starship needed. While we are still unable to replicate a gourmet meal or quickly replace the captain’s torn uniform, each year brings us amazing new manufacturing capabilities.

Automatic Guided Vehicles (AGVs) have been disrupting the Material Handling world. Now that the power of these smart mobile robots has been unleashed, each year brings new advances that are radically changing the industry. New research predicts that "Mobile robotics in material handling and logistics will become a $75bn market by 2027. It will then more than double by 2038" (Business Insider). From smart Autonomous Mobile Robots (AMRs) that move materials around a facility, to warehouse shelves that bring themselves to packers and shippers, to swarms of airport baggage AGCs (Automated Guided Carts), Material Handling is heading for more changes in 2019 than ever before.

Finding the right gasket material for sealing critical applications can be a challenge. Before engineers can even begin to think about installing and testing a new gasket, they face the critical responsibility of selecting a material that can withstand a range of operating temperatures and pressures, harsh environmental conditions, and yet is flexible enough to achieve a proper seal without failure. It is not an easy task.

As mechanical engineers push the limits of what systems can achieve, the demands put on all component parts also increases. Traditional parts made of metal, plastic, or rubber simply cannot keep pace with the demands of modern defense or industrial applications. Even in existing applications, parts are expected to last longer and reduce replacement costs. Few other gasket applications are as critical as having fail-safe gaskets on an underwater vehicle.

Great strides are being made introducing various composite materials for Industrial and Marine applications.  Composites are radically changing the cost/performance curve in the development of new products.

The Design Challenge

Globe Composite Solutions was recently contacted by an international company that was developing a new generation of outboard marine engines to fulfill the emerging global demand for energy-efficient engines. Their new engine required greater cooling capacity than typical outboard engines. In addition, the manufacturer was under a tight timeline to come up with a cost-effective solution. Globe Composite is well known for designing and manufacturing composite components that can withstand adverse operating conditions. Globe’s 30+ years of experience in providing components for pump applications was particularly relevant to address this challenge.   

According to the Center for Disease Control & Prevention, over two million individuals are injured and 32,000 are killed each year in motor vehicle accidents. As an employee of or contractor for the Department of Transportation, you have a critical responsibility to guide the flow of traffic, reduce congestion, and ultimately create a safer transportation environment for drivers. Even if you’re an owner of a large parking area at an airport, shopping mall or entertainment venue, managing and controlling traffic is essential.

Engineers are tasked with selecting the perfect material for your gasket application. Each part must be able to withstand the task at hand, including operating temperature and being flexible enough to maintain a proper seal throughout the process. 

As we discussed in our last blog, engineers historically chose asbestos because it served a myriad of important functions; it was durable, able to handle high temperatures and parts-handling, and relatively affordable. Unfortunately, it was also linked to mesothelioma, an invasive and often fatal type of lung cancer. Once it was pulled off the market, workers had to find an alternative for their gasket solutions.
