Abstract
A method of bonding a composite vane to at least one support. The method includes positioning an end of a vane within a support, causing an adhesive to flow between the vane and the support from an inlet to an outlet, and reversing the flow of adhesive from the outlet towards the inlet.
Claims14
A method comprising:
- positioning an end of a vane within a support, the positioning establishing a clearance region between the vane and the support to receive adhesive, the positioning forming a gap along at least a portion of a perimeter between the vane and the support;
- positioning an inlet at a first position of the clearance region between the vane and the support;
- positioning an outlet at a second position of the clearance region between the vane and the support;
- positioning a seal around at least a portion of the vane and the support adjacent the gap, the seal having a contour facing the gap;
- causing the adhesive to flow in the clearance region between the vane and the support from the inlet to the outlet;
- reversing the flow of the adhesive from the outlet towards the inlet;
- and
- after reversing the flow, holding inlet pressure at the inlet and outlet pressure at the outlet at about a same pressure level,
- wherein the adhesive joins the vane and the support together into a single part and the adhesive forms a fillet along the gap due to the contour of the seal.
