Park Aerospace Corp. introduces mid-toughened epoxy resin system

Park Aerospace Corp.’s (Newton, Kan., U.S.) E-752-MTS mid-toughened 350°F (177°C) cure epoxy system is designed for primary and secondary aircraft structure applications, such as wing and empennage structures, control surfaces, fuselages and engine nacelles. To provide processing flexibility and access to a wider market, E-752-MTS, the newest member of the company’s E-752 product family, can be cured using autoclave, oven (out-of-autoclave) or press cure processes. According to Park Aerospace Corp., trials and testing of E-752-MTS tack levels have yielded a resin system that is optimized for hand layup fabrication as well as automated processes such as automated fiber placement (AFP). The resin system is available with a variety of aerospace grade reinforcements including standard modulus and intermediate modulus carbon fiber fabrics and unidirectional tapes.
