Abstract
This paper is focused on extending the applicability domain of double-sided self-pierce riveting to the production of invisible lap joints in polymer sheets. The presentation draws from the working principle and identification of the main process parameters to aspects of design and fabrication of the tubular rivets and lap joints. The experimental work is carried out in polyvinylchloride sheets and stainless-steel tubular rivets and is supported by finite element modelling. It is shown that double-sided self-pierce riveting with adequate geometry of the tubular rivets can be used effectively to produce invisible lap joints in polymer sheets at room temperature with neither surface preparation and pre-drilling of holes nor material protrusions above and below the sheets after joining.
