The first commercially viable non-toxic fiber board

2013-13 NFC board

UMaine formaldehyde-free particle board sample

This invention provides particle board or fiber board that is 100% non-toxic and 25% stronger than currently available products.  This is accomplished by replacing commonly used formaldehyde based resins with a safe, renewable nanocellulose based binder.

Benefits:

  • Reduction of health problems and related expenses ($9m – $48m per year1) caused by formaldehyde exposure
  • 25% strength increase reduces material and transportation costs
  • Nanocellulose, a renewable resource, replaces binders generally synthesized from non-renewable resources

Reinforcement system increases wall panel strength by 20%

Typical failure at nail site

Typical failure at nail site

 

 

 

 

 

 

 

 

 

When stressed, oriented strand board (OSB) panels tend to fail along the edges and at nail sites, particularly if the panel has gotten wet.  This technology presents a system for waterproofing and reinforcing panel edges.  The reinforced edge improves fastener performance and reduces the edge swell and weakening caused by moisture exposure.  Reinforced edges strengthen the panel by up to 20%.

Composite Panels for Blast and Ballistic Protection

panel_installation.jpg

The Modular Ballistic Protection System (MBPS) provides soldiers with enhanced ballistic protection where it never existed before – in their tents where they work, eat, and sleep.  The system consists of composite ballistic panels that are mounted to the inside of the tent frame using an energy-absorbing connection system.  Requiring no tools, the MBPS can be used to up-armor a 20ft x 32ft tent in less than 30 minutes with 4 soldiers.

Bridge in a Backpack®

auburnbridgeforweb2.jpg

The Bridge-in-a-Backpack is a lightweight, corrosion resistant system for short to medium span bridge construction using FRP composite arch tubes that act as reinforcement and formwork for cast-in-place concrete. The arches are easily transportable, rapidly deployable and do not require the heavy equipment or large crews needed to handle the weight of traditional construction materials.

To date six Maine bridges have been built using the Bridge-in-a-Backpack technology. Several bridge projects are planned for 2012 throughout New England and beyond.

Fire Resistant Cellulose Insulation

Cellulose-fire-resistant

 

 

 

 

 

 

 

 

End users and installers of insulation want a product that is affordable, efficient and safe. Cellulose insulation, generally produced from recycled wood fiber, is affordable and outperforms fiberglass in extreme weather. But cellulose has poor insect resistance and fire retardant qualities without the addition of toxic chemicals.  Additionally, the cellulose insulation  manufacturing process currently used creates a product prone to settling, which is bad for the homeowner, and dust, which is bad for the installer.  ProCell Insulation solves all of these problems, making it a very attractive choice compared to fiberglass and other cellulose insulation brands.

The technology was developed at UMaine in collaboration with the company founders.  Company is currently developing manufacturing and distribution networks. Learn more at procellinsulation.com

Low Maintainance Sheet Piling Reduces Life Cycle Costs of Retaining Walls

PROBLEM: Commonly available sheet piling used for retaining walls corrodes, increasing maintenance costs and reducing the useful life of the construction. These problems are heightened in a marine environment.

SOLUTION: Our patented wood composite sheet piling system does not corrode, which reduces overall life cycle costs.  Additionally it is chemically inert and 100% recyclable.

Fire Proof Paint

A fire resistant paint includes a film-forming binder, a solvent, and a hydrated mineral that imparts fire resistance to the paint. The paint, when applied to a fibrous composite article which comprises at least about 20 wt % lignocellulosic fibers bound together into a consolidated fibrous article, provides the article with a flame spread index of not greater than about 50.

38% Stronger Reinforced Glulam Construction Beams

PROBLEM: Builders prefer reinforced glulam beams for applications benefiting from thier beauty or shape versatility.  But glulam beams have a tendency to weaken (delaminate, or peel) on the ends when the center of the beam is bent or stressed.

SOLUTION: UMaine offers reinforced glulam beams that withstand end delamination under 38% more bending stress compared to other reinforced beams, and 95% more stress compared to non-reinforced beams.
