A structural component of fiber reinforced synthetic resin material is strengthened by a multitude of metal or synthetic material pins extending approximately perpendicularly through the layers of fibers and resin. The pins are bonded to the fibers and resin as a result of curing the resin after the pins have been driven into the resin fiber layers in the form of so-called prepregs. The pins are bent over at their end or at both ends to further improve the strength of the structural component especially with regard to preventing peeling of one layer away from an adjacent layer.

A method for strengthening a fiber reinforced structural component in which reinforcing fibers are embedded in a resin matrix comprising the following steps: arranging at least two resin preimpregnated fiber layers in parallel to each other, securing a plurality of reinforcing pins to a pin carrier

A method for strengthening a fiber reinforced structural component in which reinforcing fibers are embedded in a resin matrix comprising the following steps: arranging at least two resin preimpregnated fiber layers in parallel to each other, securing a plurality of reinforcing pins to a pin carrier (2, 2a), pressing said pin carrier with the pins secured thereto in a direction substantially perpendicularly to a plane defined by said preimpregnated fiber layers for driving said plurality of pins into both layers so that the pins extend approximately perpendicularly to an orientation of said fibers in said layers, compressing said preimpregnated fiber layers with said pins therein, and curing said resin matrix for bonding the resin matrix to said fibers and to said pins.
