  1. Butterfly eVTOL Development Moves Ahead With Toray/Overair Partnership
    There is a company currently working on development of an eVTOL called the Butterfly. Overair is actively developing the prototype and they have recently been in the news thanks to a partnership forged between themselves and Toray -a prepreg specialist-. For the purpose of the development of the Butterfly, Toray is working with Overair using the Toray T1100/3960 prepreg system, a material that is formulated for high-performance aerospace applications where the optimal ratio of strength to modulus properties is critical. Toray's 3960 is a highly-toughened 350°F/177°C cure epoxy resin with a glass transition temperature (Tg) of 400°F/204°C. It is optimized for increased performance and allows for autoclave and out-of-autoclave curing.
  2. The resin is synergistic with the TORAYCA T1100 next-generation intermediate modulus plus (IM+) carbon fiber, which is the highest tensile strength fiber available today. The T1100/3960 unidirectional and plain weave prepreg is utilized in the Butterfly's airframe structure and propulsion units. "We're excited to be working closely with Toray's advanced materials as we continue the development of our all-electric Butterfly experimental prototype aircraft," said Ben Tigner, Co-Founder and CEO at Overair. "Our unique propulsion system requires materials that provide a unique combination of high stiffness and high strength, while also maintaining the optimal weight targets for the vehicle."
