What is the correct layup notation for a laminate which contains a biaxial non-crimp fabric (NCF)?

11 February 2020 0 2K Report

The layup contains a biaxial non-crimp fabric (NCF) with orientations +45° and -45°. Would the correct notation be [(± 45)ncf ] , or should the fabric be noted like two separate unidirectional plies [+45/-45]?
