Gasgoo Awards 2023 applicant:CFRP Rear Floor Assembly from Feize Composites Technology Co., Ltd.

Product: CFRP Rear Floor Assembly 

Description

CFRP Rear Floor Assembly consists of 3 sub-assemblies, which is floor panel, seat pan and crossmember assembly. 4 CFRP parts are included in this assembly, all of which are made by wet compression molding process. The cycle time for the wet compression molding is only 80s. Fully automated bonding and assembly line improves the stability and consistency of the part quality. Taking cost into consideration at the design phase give us the opportunity to cut the cost to a quite satisfied level.

Unique advantages

1. High efficiency. With multi-cavity mold and fast cure resin, the cycle time is reduced to 90s. 2. Fully automated bonding & assembly line. Multiple bonding & assembly technology are applied in this line. The cycle time of bonding & assembly (with a lot of bonding of metal parts and studs) is within 5 mins thanks to the reasonable layout design and process design. 3D visual online monitor system and 2D photograph system are applied to the key process of the line to guarantee the stability and consistency of the quality. 3. Low cost. With special nesting system and stacking technology, the scrap rate of the fabric is largely reduced. Optimized milling process and the introduce of cutter reuse technology enable us to largely reduce the milling cost.  4. Innovative quality control method. Combine the quality control method of automotive industry and the quality control method of the aerospace industry and develop a innovative quality control method for the mass production of CFRP parts.

Application

Over 150000 units (600000 pieces) have been produced and delivered. This product has been applied to ES6 and ES7 models successively.

Prospect

This product has pioneered the large-scale application of carbon fiber composite materials in the automotive industry of China. The mass production of this product fully meets the requirements of customers for quality, cost and efficiency. This project is regarded as the landmark of the application of carbon fiber in the automotive field.
