Abstract
Blade insert arranged inside the blade walls so that the joint between the insert and composite (1) is a double shear joint. The insert is made up of two defined parts, the head (3, 3′) and the body, which are joined together by joint elements (5) that define a double wall body (6, 6′). The joint between the insert and pultruded material (2) is made with an adhesive chemical joint (9). After making the joint, the assembly made up by the inserts and pultrusion profiles (2) is fitted into the blade walls during its manufacturing process and material curing.
Claims9
A blade insert fitted to the inside of a sandwich lamination made up by composite skins and pultruded material core in the shape of a cell, comprising
- the insert includes a head (3, 3′) and a double wall body (6, 6′) joined together with external elements (5),
- the double wall body (6, 6′) is inserted inside the sandwich lamination with a pultruded fibre (2) between the two walls
- a joint between the insert and pultruded material is made with an adhesive chemical joint (9).
A method for positioning an insert inside a composite sandwich lamination with pultrusion profiles in its core, comprising
- injecting an adhesive into a prior assembly of an insert and the pultrusion profile until the gaps between the double walls (6, 6′) of the insert and the pultrusion profile (2) inside it are filled
- curing the adhesive (9)
- fitting the assembly made up of the insert and p rofiles during the lamination process of the blade walls.
