Composite panel for joining with a clinch joint and method of forming a clinch joint

摘要

An assembly comprising a first composite fiber reinforced part that is joined to a second part by a clinch joint. The first part includes a first layer of resin that is reinforced with fibers and a second layer of resin that is devoid of fibers and applied to one side of the first layer of fiber reinforced resin. The second part contacts the first layer of the first part. The first part and second part are joined by a clinch joint including a pressed out portion that is pressed into a clinching portion. The second layer of resin contains the fibers in the first part. An alternative assembly has fiber-free intended clinch joint forming areas that extend through the first part. A method is provided in which a first part including a first layer of resin reinforced with fibers is molded with a second layer of resin on one side of the first layer is joined by a clinch joint to a second part.

主权项

1. An assembly comprising:
a first part including resin reinforced with fibers throughout except in areas that are intended clinch joint forming areas; and a second part joined to the first part by a clinch joint formed as a pressed-out portion in the intended clinch joint forming areas pressed into a clinching portion of the second part, wherein a lack of fibers in the intended clinch joint forming area avoids exposed fibers in the clinch joint.
