Abstract

A method of bonding a thermoplastic component to a carpeted component is provided. The method includes providing a base component, a thermoplastic component and a fibrous carpet or mat between the components. The carpet has a large number of cavities. The carpet is made of a thermoplastic material adapted to bond to the thermoplastic component in response to heat at the interface between the thermoplastic component and the carpet. The method also includes heating the thermoplastic component and the carpet at the interface between the thermoplastic component and the carpet for a period of time to soften the carpet. The method finally includes pressing the components and the softened carpet together under a pressure to cause the softened carpet to flow and at least partially fill the cavities. The carpet at the interface is transformed into a solid bonding layer to bond the components together to create a finished structure.
