Summary Today, service monitoring for maintenance is a major aspect concerning durability of composite structures in industrial applications. According to these considerations, repair concepts should be a part of specifications in the product quality assurance schedule. These repairs, sometimes costly, are defined by the following stages: damage detection (for example, by NDI methods) and preparation of damaged areas. The present study deals with manual and cheap repairing on glass/polyester damaged pultruded structures. These repairs require an appropriate machining of the damaged area and a specific patch application.
First, fatigue tests provide an optimisation of repair patch per profile type submitted to standard drilling. Secondly, impact tests are used to simulate pragmatic damages in original shapes. Next, an analyse is carried on the reparability of the structures according to the damage extent introduced by the different impact configurations. With the higher limit of feasible restoring, repair procedures made after impact solicitation are validated by satisfactory residual behaviour in static, fatigue and impact tests.
