METHOD OF BONDING A THERMOPLASTIC COMPONENT TO A CARPETED COMPONENT AND THE CARPETED COMPONENT TO A CELLULOSE-BASED CORE IN A SINGLE PRESSING STEP

摘要

A method of bonding a thermoplastic component to a carpeted component and the carpeted component to cellulose-based core in a single pressing step is provided. The method includes providing a base component of a reinforced thermoplastic material, the thermoplastic component, a fibrous thermoplastic carpet or mat between the components, a sheet of thermoplastic adhesive and a core of cellulose-based material. 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, the sheet, the core and the softened carpet together under a pressure to cause the softened carpet to flow. The carpet at the interface is transformed into a solid bonding layer to bond the components together and the sheet bonds the base component and the core together to create a finished structure.

1. A method of bonding a thermoplastic component to a carpeted component and the carpeted component to a cellulose-based core, the method comprising:
providing a base-component of a reinforced thermoplastic material, a thermoplastic component, a fibrous carpet between the components, a sheet of thermoplastic adhesive and a core of cellulose-based material, the carpet having a large number of cavities, the carpet overlying and in contact with the base component and the thermoplastic component overlying and in contact with the carpet, the carpet being 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; 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; and pressing the components, the sheet, the core and the softened carpet together under a pressure to cause the softened carpet to flow and at least partially fill the cavities wherein the carpet at the interface is transformed into a solid bonding layer to bond the components together and the sheet bonds the base component and the core together to create a finished structure.
