Glass/Polycarbonate (G/PC) laminated safety glasses, which is bonded by acrylic interlayer (ACIL), is often applied for the viewing port of the machine tools. The viewing port for the machine tools requires impact resistance, transparency, and solvent resistance. The G/PC laminated safety glass has excellent characteristics to satisfy those requirements. Recently, thinner structure and weight saving have been more required for the G/PC laminated safety glass. Impact absorption capacity of the G/PC laminated safety glass is influenced by the mechanical properties of ACIL. In this paper, dynamic mechanical properties of ACIL containing CNFs were investigated and master curves were made by using Williams-Landel-Ferry (WLF) equation based on the Time-Temperature superposition principle. As a result, storage modulus and loss modulus of ACIL with CNFs decreased at inflection region by glass transition compared to those without CNFs. Also, loss tangent curves of ACIL with CNFs shifted towards lower temperature than those without CNFs.
