Objective: the purpose of this study will be to optimize polyamide 6(Nnylon-6) by electrospinning and to determine the improving effect of flexural resistance properties of this composite nanofibers, aligned or non-aligned on direct adhesive fixed partial denture. Method: Nylon-6 will be dissolved 10% HFP (1,1,1,3,3,3-hexafluoro-2-propanol) and left overnight stirring and sonicated before electrospun. Two different composites nanofibers disposition will be made using high voltage and a collector with 120 (non-aligned) and 6.000 (aligned) rpm for 10h, and dried in vacuum woven at 32oC/24h. Twenty strips with 2x25mm of each will be prepared as reinforce, inner composite resin 2x2x20mm (GrandioSO-VOCO), for flexural test in a universal test machine at a crosshead speed of 1 mm/min.
