Abstract:

Existing nanocomposite materials used for satellite applications dont offer the required conductivity and electromagnetic shielding protection, requiring metal shields in order to survive in space. The AFRL Materials and Manufacturing Directorate in conjunction with the private sector have developed a material that promises to blend the attributes of nanocomposites and metal materials. The M55JRS3 material consists of carbon fibers combined with a polyisocyanate matrix, in which nickel nanostrands are added. The research effort investigated the changes in the EMI and ESD of the material after being subjected to cyclic loads. Four configurations of a symmetric layup with fibers oriented at 09045-45 degrees were evaluated. Three of the four configurations midplane, exterior, and interlaminar had nickel nanostrandsTrademark added in different locations of the material. The exterior configuration had the best performance for resistance and EMI measurements for all stress levels. Evaluations of tested specimens showed that nickel nanostrands were undamaged during the test.
