The TenaxTM prepreg used for the nacelle part was developed especially for aircraft applications using high-performance and rapid-curing epoxy resin. Notably, the TenaxTM prepreg can be molded at a lower temperature and in a shorter time than conventional prepregs for aircraft applications. In addition to general autoclave molding, the TenaxTM prepreg also is suited to press molding for mass production, achieving excellent quality required for aircraft applications. Furthermore, it is compatible with automated fiber placement (AFP) therefore can be combined with automatic laminating technology and short-time molding to maximize production efficiency. The excellent productivity and cost efficiency of the TenaxTM prepreg were key reasons why it was adopted for Nikkiso’s nacelle.
