METHOD FOR JOINING THERMOSET COMPONENTS

摘要

A method for joining one or more first-type thermoset components to a second-type thermoset component, each first-type thermoset component being manufactured by providing an uncured starting thermoset component on which a thermoplastic material layer is placed, such that an interpenetrating network forms between the thermoset polymer of the starting thermoset component and the corresponding thermoplastic material layer when each first-type thermoset component is cured; and each first-type thermoset component being then placed on an uncured second-type thermoset component so that when the latter is cured, a further interpenetrating network forms between each thermoplastic material layer and the thermoset polymer of the second-type thermoset component; this results in a strong joint between the first-type and the second-type thermoset components.

主权项

1. A method of joining thermoset components comprising the steps of:
providing at least one first-type thermoset component, each at least one first-type thermoset component being manufactured by: providing a starting thermoset component, the starting thermoset component being uncured, placing a thermoplastic material layer on a surface of the starting thermoset component, the thermoplastic material layer having a thermoplastic glass transition temperature, curing the starting thermoset component at a first-type curing temperature, thus giving rise to the first-type thermoset component having, once cured, a filmed surface coated with the thermoplastic material layer, the thermoplastic material layer being joined to the first-type thermoset component by means of a first-type interpenetrating network; providing a second-type thermoset component, the second-type thermoset component being uncured; placing the filmed surface of each at least one first-type thermoset component on the second-type thermoset component; and curing the second-type thermoset component at a second-type curing temperature, so that a second-type interpenetrating network is created between the second-type thermoset component and each at least one thermoplastic material layer, thereby joining each at least one first-type thermoset component with the second-type thermoset component.
