Abstract

The invention discloses a rapid punch forming process for a thermoplastic carbon fiber composite board. The rapid punch forming process for the thermoplastic carbon fiber composite board comprises thefollowing steps that the thermoplastic carbon fiber composite board is put into a punching die at first, then the thermoplastic carbon fiber composite board is heated to reach and be kept at the temperature 10-20 DEG C lower than the viscous state temperature of the thermoplastic carbon fiber composite board, then the punching die is started to punch the thermoplastic carbon fiber composite board, then heating is stopped, and the thermoplastic carbon fiber composite board is cooled to be at the room temperature, demolded and taken out. The rapid punch forming process for the thermoplastic carbon fiber composite board is convenient to operate, simple in process and good in effect, the machined and formed thermoplastic carbon fiber composite board is high in quality, and punch forming of the thermoplastic carbon fiber composite board can be finished easily, conveniently and rapidly.

Description

technical field [0001] The invention belongs to the technical field of composite material processing, and in particular relates to a rapid stamping forming process for thermoplastic carbon fiber composite plates. Background technique [0002] Lightweight and energy-saving are the current development trends of the world's automobile industry. Under the challenges of resource and environmental issues, automobile lightweight has become an important means to improve fuel efficiency. Today's automobile lightweight methods mainly include material lightweight and structural lightweight. The parts made of carbon fiber composite materials are light in weight and high in strength, and have been widely used in aerospace, automobile manufacturing and other fields. Some commonly used composite material molding methods, such as hand lay-up molding, are complex in operation and low in production efficiency, and cannot meet the industrial requirements of mass production. Therefore, in orde...
