In the true definition, a composite material is simply a material that has two components which total strength combined, is greater than the sum of their individual components. For composites, 1+1 does not equal 2, but rather much, much more. There are many examples of composite materials, for example, particleboard is technically a composite. (wood and glue). However, in the modern world,

Investing in composite materials is likely a good idea, it seems that their is a daily news report about a product utilizing composites or carbon fiber. The truth is, more and more products are integrating composite materials because they are higher performing. Additionally, as the composites industry further matures, manufacturing costs should continue to decrease. The fact of the

In order for the full utilization of carbon fiber in automotive applications. (Which is necessary to lower weight.) The cost of raw carbon fiber needs to decrease. Oak Ridge National Laboratory (ORNL) is taking on this challenge using $34.7 million in DOE ARPA funding; they are establishing a Carbon Fiber Technology Center. According to their website: The center will be capable of producing up to

Cutting Kevlar or any aramid fiber is no easy task. It's tenacity wears our tools and blades, while cuts are often frayed. Probably the best method for cutting laminated aramid fiber, is using a waterjet (as seen above). Although not cheap, these cuts are CNC controlled, so very accurate, and the cut edges are clean and burr free... Related Posts: Spider Web Composite Armor - Biomimicry -

The demand for environmentally friendly materials is growing and will continue to grow. Strongwell, perhaps the world's largest pultruder, recently announced their Green Initiative. This is a fantastic move in the correct direction. Products made with composite materials are in fact environmentally friendly. Composites are inherently lightweight and non-corrosive, which is why they are used in

2010 was a fantastic year for defense appropriations for composite companies, in particular, composite armor received substantial funding. Even though it is only April, Senators are beginning to announce their 2011 requests. Senator Jim Bunning of Kentucky announced some of his requests, and looks like 2011 will be another stellar year for composite armor funding. Below are Bunning's related

Today is the last day of the JEC composites show in Paris. This is probably the largest composites show in the world, and has become the annual meeting place for composite material companies from all corners of the globe. However, this years show may be lasting a little longer; volcanic ash from Iceland is about to shut down all the airports in Paris. The ash can damage airplane engines and

The clip above demonstrates why the new Joint Strike Fighter needs to be as lightweight as possible. Carbon fiber is undoubtedly playing a role in reducing the weight. I caught a fascinating NOVA episode on the competition between Lockheed and Boeing in designing the F-35. It goes into a surprising amount of detail of the composite construction and even discusses how Boeing attempted to use

Composites, which are often structurally bonded with adhesives, are always looking for a better product. So when adhesive researchers need inspiration, what better place to look then nature (Biomimicry). Some researchers have looked at shellfish, such as how mussels are able to adhere so well to wet rocks in a turbulent environment. However, recent research is looking into the sandcastle worm.

Here is an interesting article about a company called GENER8. They have developed a composite prosthetic leg out of what appears to be carbon fiber. Unlike similar composite prosthetic legs which can cost between $700 - $5,000 each, GENER8 is shooting to provide their design at a price below $500. Their current target market is developing countries where affordable options are not currently

I once heard a leading wind turbine expert say, "The most important advancement in wind energy was advanced breaking, and in particular, the air-brake." Breaking allows a turbine to operate in higher wind speeds; it also makes a wind turbine safer. Here is recent news of a wind blade breaking at Europe's largest onshore wind farm. I would be interested to see what the culprit was...

Composite baseball bats are gaining popularity in softball and little leagues world wide. Using carbon fiber and epoxy, these composite bats are said to have such good performance, that they are now banned for use in NCAA play. Much like other composite products, the big draw to the bats is their lightweight yet powerful capabilities. What is interesting though, is that while most composite

Wind farm development has seen resistance from a variety of people/groups. Some environmentalists fear the safety of bats and birds caught in the path of the blades. Local residents of potential developments fear blocked views, noise, and even flickering of shadows. Another concern, is the disruption wind turbines can have on radar. Here is a recent ABC News article discussing the Pentagon's

We have talked before about life cycle assessment (LCA) of products manufactured with composite materials. Here is a paper discussing the life cycle of a surfboard. A surfboard is more or less a composite sandwich structure. The core is either a polyurethane foam core or eps foam core. A wood stringer is added down the center for stiffness. The skins are generally woven 4oz fiberglass, often 2

There are a few building materials already using recycled plastic; some composite decking products use recycled polyethylene grocery bags. The video above describes a whole new building product. Here, it appears the variety of ground up plastics are held together by a thermoset. If this is the case, the plastic will act as the reinforcement in the new composite material... Related Posts:

  Composites will continue to gain acceptance in the biomedical field. When compared to metals (titanium, nickle, stainless, etc) used in bio medical, composite materials have some distinct advantages. Composites are x-ray transparent allowing doctors to take less x-rays to better see injuries and how they are healing. Many patients have allergies to nickle and other alloys, which limit

Obviously the US Department of Defense is one of the largest customers and users of composite materials, however, as technology advancements and military budgets expand in countries such as China and India, so will the demand for composite materials.
