The Maine Composites Alliance is an alliance of composite businesses in Maine who work together to recognize and promote Maine’s leadership in the international composite industry. Maine's composite industry is comprised of small and mid-sized shops that deliver innovative, high-quality, cutting-edge design and manufacturing services for the marine, automotive, aerospace, architecture and industrial industries in Maine, as well as for businesses throughout the United States and around the world.

Composites are increasingly the material of choice because they are environmentally friendly while offering significant performance improvements. Over the next several years, wind energy, transportation, and construction are expected to be the dominant markets driving growth in the use of composite materials. The Maine Composites Alliance is positioning its members to meet the needs of these burgeoning markets.

ORPC has made great advances in the development of its proprietary ocean current generation (OCGen™) technology and is developing tidal energy projects in three of America’s most robust tidal energy resources: Western Passage and Cobscook Bay, Maine and Cook Inlet, Alaska.

Located in Bath, ME, US Windblade is a new company at the forefront of developing new composite manufacturing technology for replacement (7.9 meter) windblades. US Windblade designs and manufactures highly efficient and cost-competitive blades for the small wind turbine market and was a recent recipient of a Maine Technology Institute grant to develop alternative surface coating for wind turbine blades. The company will develop a process that uses laminating resin for windblade surface coating, eliminating the conventional windblade gel coat process. The new resin process provides reduced manufacturing costs, improved durability and elimination of toxic gases as part of the coating process.

Harbor Technologies Inc. (HTI) was founded in 2003 to meet the growing need for cost-effective environmentally friendly building products for the marine environment. The current cost of maintaining and repairing rusting steel and worm eaten wood has created an ever-growing market opportunity for long-lasting and environmentally-friendly composite solutions.

HTI manufactures cost-competitive products that solve these problems by using composites and innovative process technology. The company’s products are used for marine infrastructure construction, providing the basic framework for building piers, ports, harbors and marinas. Specifically, HTI’s products for this market are composite pilings, composite dock systems, stay-in-place concrete forms, as well as composite decking. HTI delivers complete system solutions that offer fast construction methods and long-lasting solutions that outperform conventional construction systems in both cost and longevity.
