Optimum Performance, Lowest Total Cost
TPI is proud of our long-standing history of first-of-its-kind innovations in composite products as well as the development of new and advanced materials, tooling, manufacturing processes and inspection methods. Our diverse experience and detailed knowledge of composite materials and manufacturing traces its roots as a company to Tillotson Pearson Inc., a leading manufacturer of high-performance recreational sail and powerboats along with pioneering a wide range of composite structures for industrial applications. Leveraging this knowledge and experience, TPI has become the world’s largest independent manufacturer of utility-scale wind turbine blades. The company is now striving to capture significant share in automotive and transportation markets where significant weight reduction, high-precision, and competitive costs are paramount.
We conduct extensive research and development (R&D) in close collaboration with our customers on the design, development and deployment of innovative manufacturing processes, including automation, innovative material application and sophisticated product quality inspection tools. TPI has partnered with the U.S. Department of Energy and the national laboratories for the past 25 years, focusing on the expansion of clean wind energy through industry leading design, manufacturing and testing of wind blades. We built the world’s first 3D printed set of tools and molds with Oak Ridge National Labs and fabricated multiple sets of blades for Sandia National Labs National Rotor Testbed.


In addition, TPI is a founding member of the Institute for Advanced Composite Manufacturing Innovation (IACMI). IACMI is one of 15 US sponsored National Network of Manufacturing Institutes established specifically to reduce manufactured cost of composite based products for wind blades, automotive components and compressed natural gas storage systems.


Our research and development efforts place a priority on improving quality through continuous process improvement, while reducing cost by improving specifications, cross-qualifying materials and developing a more diverse supply chain. Other areas of emphasis include composite design, in-house fabrication of precision molding and assembly systems, prototyping, testing, optimization and effective scaling of production methods. TPI places a premium on state-of-the-art methods to improve design and manufacturing. We have pioneered the use of model-based manufacturing to ensure the preparation, planning and execution of our manufactured products meet the highest standards with the very first part produced.
TPI encourages innovation from our associates and provide the resources for invention and development of new technologies to maintain our industry leading competitiveness in the marketplace. In addition to our internal research and development activities, we also pursue funded research and development in collaboration with our customers and other third parties.
