Why Carbon Fiber Might Someday Compete with Wood

Confessions of a Non-Profit IT Director - June 15, 2019 - 4:16am

If you were building a bike frame and could choose between carbon fiber and wood, which material would you choose? It is a safe bet that carbon fiber would be the obvious choice in nearly every case. And yet, it’s quite possible that carbon fiber might find itself in competition with wood at some point in the near future.

Thanks to research being undertaken at the University of Maine, in partnership with the U.S. Department of Energy’s Oak Ridge National Laboratory, wood fiber products fabricated with 3D printing technology are right around the corner. The research focuses heavily on what is known as cellular nano fiber (CNF) technology.

3D Printing Carbon Fiber

Creating a carbon fiber part using a 3D printer starts with choosing the right carbon fiber thread. That thread is manufactured by subjecting carbon molecules to high heat and pressure. The high heat and pressure forces the molecules to align end-to-end to create a long chain that behaves very much like any other kind of thread.

Carbon threads can be used in any number of ways. For 3D printing purposes, thread is run through a printhead where, upon outflow, it is married with a resin and laid in place. A carbon fiber reinforced plastic is created when the two materials fuse together and cure.

3D printing with carbon fiber allows parts to be made in place without the need for manual layups, expensive tooling, and autoclave curing. While the technology is limited for now, it shows great promise for carbon fiber fabricating down the road.

3D Printing Wood Fiber

Printing with wood instead of carbon is quite similar in principle. Nano and micro cellulose fibers are joined together to make a thread product similar to carbon fiber thread. The resulting material is then fed through a similar printhead and married with an epoxy resin.

The resulting material is every bit a reinforced thermoplastic. The wood fibers perform the same function in the resulting material as the carbon fibers in a carbon fiber reinforced plastic. They provide additional structural rigidity without adding significantly to weight.

As for their strength as compared to carbon fiber, there is not enough data yet to reach any definitive conclusions. But even if nano and micro-cellulose reinforced thermoplastics turn out to be not as strong as their carbon fiber counterparts, it’s likely they could still be used for nonstructural parts in much the same way recycled carbon fiber is.

Bringing Down Composite Prices

Salt Lake City’s Rock West Composites says the appeal of wood fiber products is mainly in their cost. Carbon fiber is as expensive as it is because producing it requires a tremendous amount of energy. Even when 3D printing is the chosen fabrication method, carbon fiber is still more costly than most other building materials. Wood fiber plastics would be different.

We already have the technology in place for transforming wood into nano and micro cellulose fibers. Not only that, the process is comparatively cheap. It is conceivable that wood fiber plastics could offer the cost benefits certain industries need to delve more deeply into composites.

According to Composites World contributor Scott Francis, successful research at the University of Maine could also be a boon to that state’s timber industry. As the world is transitioning away from wood-based products for construction and manufacturing, the timber industry needs to develop a new customer base. That customer base could very well be established through wood fiber composites.

Carbon fiber currently has few competitors. That could change in the future, with wood fiber becoming carbon fiber’s chief rival.

An Amazing Online Summarizer For Text

Confessions of a Non-Profit IT Director - June 10, 2019 - 3:18am

In these modern days where so many things are competing for our time and many schedules to clear, it then becomes important that we are productive in whatsoever we do. Most especially when we are on the web reading and searching a multitude of text that we need to produce. It is to this end that many tools are created daily to help us to be productive and effective when it comes to text reading, research or writing of any piece, be it news, article, essay, etc. One of such tools that can help us to be effective with respect to making meaning out of a large amount of data is a text summarizer.

A text summarizer is a text summary tool that goes through a bunch of text and generates a summary of the most important facts and ideas in an article, argument, news, or essay. One amazing online text summarizer that you have out there is the Resoomer text summarizer. This summarizing tool has an algorithm for carrying out a good semantic analysis for determining the sentence that is important to the central idea and main facts of an article. This is amazing as it removes the huddles of reading through the whole text.

Resoomer, An Accurate Text Summarizer

Most online summarizers tend to do pretty well in summarizing text contents of articles, essays, news arguments. However, the Resoomer text summarizer has been very accurate in summarizing articles and papers. This is great as it makes the preparation of lessons very easy and super-fast. It takes less time in generating the main ideas and important facts in any multitude of text automatically to create summaries when compared to reading the whole text manually to process and produce the important information. A great quality of Resoomer summarizer is that it is not difficult to use as it only involves one simple click of the mouse.

Do not overconsume information and news online with a text summary tool

When we browse the internet, we are always confused and overwhelmed by the amount of information and data that we have to process and consume because they are very large we may be forced to just scan through the information which may not be relevant to us without getting the important facts. This problem or confusion has been addressed by the development of online or web-based text summary tools which help to generate summaries from a multitude of texts. These tools have made our online search and reading very easy as we do not need to be bothered by how long a text is again. One great summarizing tool that is effective in generating accurate summaries is the Resoomer summary tool. It is very accurate and creates simple summaries.

Why not use a summary tool today?
