Method for joining two fiber-reinforced plastic components by metallic joining element, involves driving setting bolt through fiber-reinforced plastic-components as joint element and subsequently through metal sheet lying in joint area

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for joining two fiber-reinforced plastic components together using a metallic joining element. A setting bolt is driven through the plastic parts and a metal sheet at the joint area, and then securely bonded to the metal sheet using welding techniques such as resistance or friction welding. This results in a strong, integrated joint between the fiber-reinforced plastics and the metal element.

Patent Abstract

The method involves driving a setting bolt (3) through the fiber-reinforced plastic-components (1,2) as a joint element and subsequently through a metal sheet (4) lying in the joint area (5) for fixing the overlapping fiber-reinforced plastic-components in the joint area. A firmly bonded connection is established between the setting bolt and the metal sheet by resistance welding or friction welding. A circular ring-shaped metal disk is used as the metal sheet. An independent claim is included for a device for executing the method.
