Abstract

Metal – Continuous Fiber Reinforced Thermoplastic (CFRT) hybrid parts offer new possibilities for lightweight application, which often exceed the capabilities of mono material parts. Oftentimes, in this application, the joining technology is the limiting factor. The present study investigates a joining operation with additively manufactured metal pin structures with different diameters and tip geometries, which are pressed into locally infrared heated CFRT parts. The resulting joint strength is assessed for different pin geometries. It could be shown that pins with larger diameters lead to higher absolute joint strengths and that a fl at cylindrical pin shape is advantageousm in means of joint strength in comparison to tapered pins. When dividing the maximum shear strength by the pin foot cross sectional area as a measure of the utilization of a given joining space, pins with smaller diameter are beneficial.
