I read recently that worldwide, 3 Cr. (30 million ) bags are lost every year. Of these, 95 % are retrieved by airlines and returned to their owners, which means they were just misdirected (sent to the wrong destination – the passenger going one way and the baggage another), while 5 % are actually lost. The causes: Not loaded on your aircraft at all, tagging error, someone else taking away your bag thinking its his/hers, mishandling on arrival (like being put on the wrong baggage carousal)..

If you decide the tooling (e.g., if you are a programmer, process planner or industrial engineer), you have to know the naming convention thoroughly, as well as the logic behind selecting the shape and size of an insert.

To new users of carbon fiber, understanding the properties of carbon fiber is often challenging. To some, it is a mysterious material. This is why we are here.

In addition to being directionally dependent (anisotropic), there are many other factors in determining the properties of carbon fiber. Some of the key factors are:

Clearwater Composites is an expert at carbon fiber and composite materials. We understand the materials down the fiber level and we know how best to tailor the carbon fiber design to achieve your needs. And, it is our intent to educate our customers, and the community at large, as best possible, as we strongly believe that the more engineers, designers, students, hobbyists and the public-at-large learn and understand about carbon fiber, the more widespread it’s use will become.

Nevertheless, the table below is shown for comparison purposes to help the end-user get a better understanding of the properties of the more common laminate designs of carbon fiber products sold by Clearwater Composites. The properties of other common materials, like steel and aluminum, are also shown for comparison purposes.

When selecting a carbon fiber product or designing with carbon fiber, one of the most important considerations is knowing the direction of the property of interest. Unlike metals, carbon fiber, and composites in general, are called anisotropic materials. This means the properties of the material are directionally dependent. For an easy analogy, think of a piece of wood. The strength of wood is dependent on the orientation of the grain.  This is true with carbon fiber – the strength of the carbon fiber is dependent on the orientation of the fiber (grain). On the other hand, metals, plastics, and most common materials have the same properties in every direction. They are called isotropic materials.

What’s worse than having your bag disappear into the airline system ? Getting it, but after one of these happens to it:– In 2010, a waste pipe burst in London’s Heathrow airport, burying 240 suitcases in human waste.– Bags on the tarmac in an airport in the US were soaked in jet fuel.– Some bags caught fire in an airport (again in the US) because they were placed too close to the engine after unloading.

So what happens if your bag is among the 5 % that are lost forever ? You get a compensation, and the bag ends up unclaimed in some airport. Its contents are either auctioned off (here’s the auction site of IGI Airport, New Delhi) or given to charity.

All of the factors above, or design options, are a unique advantage of carbon fiber and advanced composite materials.  A part using carbon fiber can be tailored and designed for a specific application.  The fiber type, fiber amount, fiber orientation, etc can all be changed to achieve certain properties, whether for mechanical reasons (strength, stiffness) or for other reasons, such as low CTE (coefficient of thermal expansion).  Metals and other materials do not have this tailor ability.  For example, on a metal part, the only thing that can be changed is the grade or alloy of metal and it’s thickness or shape.  That’s it.

Note: Properties of carbon fiber composites are dependent on the direction and the properties shown above are ONLY valid for one direction, typically referred to as the longitudinal direction.

Inserts, those SMALL things that we use to cut material, have a BIG impact on our shop’s profitability. It makes sense to know ISO turning insert nomenclature. Here is a quick explanation that makes it easy to remember insert names.

Because there are literally thousands and thousands of options when it comes to carbon fiber, it is impossible to list and explain all of the potential properties of carbon fiber.

Inserts are known by an ISO naming convention that describes their shape and size. Each alphabet and number in the name signifies an aspect of the insert’s shape or size. E.g., the first alphabet is the shape, while the last two numbers are the nose radius.
