| Résumé : |
Composite manufacturers are facing increasing pressure to improve operational efficiency, identify saving opportunities and reduce their ecological footprint, without compromising material performance. The implementation of an ultraviolet (UV) curing manufacturing process is proving to be an effective step towards these goals. Before considering such process improvements, maanufacturers and OEMs should be aware of the benefits and boundaries of the current state of the art in UV curing technology. |

- BENEFITS AND BOUNDARIES : WHEN TO CONSIDER USING UV TECHNOLOGY ? : Prepregs : stable storage and fast, controlled curing - Pultrusion : increased line speed, reduced energy consumption and cleaning labour - Filament winding : reduced cycle time, energy cost and number of mandrels in use - In-field repair : fast return to service and high process control - New opportunities
- MATERIAL PROPERTIES
- Table : Viscosity, glass transition temperature (T(tanδmax) determined with dynamic mechanical analysis) and flexural properties of three typical UV-cured systems
- Fig. 1 : Possible implementation scheme of a filament winding process with UV curing
- Fig. 2 : Flexural modulus versus temperature of non-reinforced UV-cured resins and a typical glass fibre-reinforced (fibre content : 83wt %) UV-cured composite relative to monolithic glass. The set of UV-cured resins ranks from grey to black according to an increasing level of crosslinking density from medium to high |
