Calcium phosphate cements (CPCs) are extensively used as synthetic bone grafts, but their poor mechanical properties limit their applicability to non‐stress‐bearing applications. The aim of the present work is to evaluate the potential of plasma surface modification of polylactide (PLA) fibers for reinforcement of CPCs. Oxygen low‐pressure plasma was employed at different treatment times and the surface properties of the untreated and plasma‐treated PLA were evaluated. Plasma treatment on the PLA fibers reduced the setting times of the PLA–CPC composites and improved their flexural properties.
