Method for manufacturing a composite element with fibres embedded in a cured resin and an insert piece also embedded in the resin, which has a head and a point, and a pin is provided between the head and the point, the pin extending along a longitudinal axis, which points from the head to the point, wherein a mounting hole is made in the head and/or a mounting projection is provided on the head, wherein a recess is provided on the pin, on which recess a retaining surface is formed facing the head at an angle of >0° and <180°, in particular an angle of >10° and <170° to the longitudinal axis, wherein the insert piece was manufactured from a semi-finished product according to one of claims 2 to 7, wherein the semi-finished product has a head and a point, and a pin is provided between the head and the point, the pin extending along a longitudinal axis, which points from the head to the point, wherein a mounting hole is made in the head and/or a mounting projection is provided on the head, wherein a recess is provided on the pin, on which recess a retaining surface facing the head is formed at an angle of >0° and <180°, in particular an angle of >10° and <170° to the longitudinal axis, wherein the semi-finished product is surrounded by fibres and a liquid resin, and the resin is cured, in which • a device is provided with an upper part, in which the semi-finished product is held, wherein the device has a lower part and a cavity is made in the lower part, the shape of the cavity matching the shape of the point of the semi-finished product, • several layers of a fabric of fibres are stretched between the upper part and the lower part, • a supply of resin 55 is situated above the fabric in the upper part, • the point of the semi-finished product held in the upper part dips into the supply of resin, • a die is provided, which can press the semi-finished product through the supply of resin into the fabric, • the supply of resin is liquefied at the moment the semi-finished product is pushed in, • the liquefied resin of the supply of resin together with the semi-finished product is pressed by the die between the fibres of the fabric, • the point of the semi-finished product divides the fibres of the fabric, wherein the point pushes the fibres of the fabric aside and/or the point of the semi-finished product separates the fibres, and • the resin is cured after the semi-finished product is pushed in. wherein a mounting hole is made in the head and/or a mounting projection is provided on the head, wherein a recess is provided on the pin, on which
