Introduction:Poor interfacial bonding between the fibers and resin matrix in fiber-reinforced composites (FRCs) is a significant drawback of composites.To enhance mechanical properties FRC, were modified by depositing SiO 2 nanofilms via atomic layer deposition (ALD) technique.This study aims to evaluate effect ALD treatment on FRCs.Methods: The quartz different cycles (50, 100, 200, 400) technique FRCs proposed from fibers.The morphologies, surface characterizations nanofilms, properties, cytocompatibility systematically investigated.Moreover, shear bond strength (SBS) human enamel was also evaluated. Results:The SEM SE results showed that ALD-deposited have good conformality homogeneity.According FTIR TGA, fiber surfaces had chemical combinations.Three-point bending tests with deposited effectively improved FRCs' Group D underwent 100 highest flexural before after aging.Furthermore, demonstrated crescendo-decrescendo tendency nanofilm thickness increasing.The SBS outstanding performance.Moreover, cytotoxicity experiments such as cck8, LDH Elisa, etc., cytocompatibility. Conclusion:Changing number reaction affects FRCs, which may be related stress relaxation fracture layers built-up internal stresses nanofilms.Eventually, could performance improving strength,
