Abstract
The invention relates to method for obtaining a part made of a composite of fibers embedded in a resin matrix which comprises a body and an edge. The method comprises a first step of stacking plies of fibers and further comprises a step of curing the plies. The method further comprises prior to the curing step, the step of covering the edge with at least one additional ply, in order to compensate for the migration of the resin during curing.
Claims7
A blank made of composite material comprised of a plurality of plies, the blank comprising:
- a body;
- and
- an edge, wherein the edge comprises a zone to be removed and said zone includes at least one additional ply, said additional ply having a width smaller than a width of the zone to be removed.
A blank including an edge zone to be removed to make a desired part, said blank comprising:
- a plurality of fiber layers embedded in a cured resin matrix, said blank having a desired thickness, and
- said edge zone including at least one fiber layer in additional to said plurality of fiber layers, wherein said at least one additional fiber layer partially covers said edge zone to be removed and has a smaller width than the width of the edge zone to be removed.
