摘要：
The present invention relates to a composite sports article (10). The composite sports article (10) comprises: (a) a first component (11) and (b) a second component (12), which was produced by means of an additive manufacturing technique. (c) The first component (11) and the second component (12) are bonded to each other by a first bonding agent (13) and there is a form-fitted bond between the first bonding agent (13) and the second component and/or (d) the first component (11) and the second component (12) are bonded to each other in a form-fitted manner via a first bonding agent (13).
技术问题语段：
Especially on the second component, the chemical bond of the bonding agent may be very weak.
技术功效语段：
[0023]The composite sports article may be a shoe, the first component may be a part of a shoe upper and the second component may be a part of a sole. The term "upper" in the context of the present invention refers to a "shoe upper" unless anything else follows from the context. A shoe in the present context is any type of shoe, for example a soccer boot, a hiking boot, a running shoe, or a sandal. The present invention is greatly beneficial for a shoe, which needs to be strong and durable as it is exposed to the whole weight of the athlete. For example, a weak bond between the shoe upper and the sole may increase the risk of the upper tearing off the sole during physical activity. The shoe also needs to provide the right level of support, for example around the ankle, yet it has to be flexible, for example in an instep region and provide the right level of cushioning, for example in a heel region. Thus, it is of advantage to form the shoe as a composite article. A sole at least partly formed by means of additive manufacturing techniques allows for the right level of cushioning for each part of the foot and may be individually customized for the athlete. For example, the heel region may be engineered to provide a high level of cushioning while the toe region may be engineered to be firmer than the heel region. The present invention therefore provides a composite shoe with a preferred level of fit and ideal functional properties that is at the same time durable due to the strong bond between the shoe upper and the sole.
[0110]Applying a sheet of solid bonding agent to the bonding location may be performed when the shoe upper is in a flat condition. It is easier to place a sheet of solid bonding agent to the shoe upper when it is in a flat condition. This may, for example, be performed fully automatically by a patch placement machine.
