Forming of thermoplastic plain woven carbon composites

Abstract

By combining carbon woven fabric with thermoplastics, a thermostamping process was proposed to form composite parts with complex double curvatures in one step and to implement affordable application of fiber-reinforced composites in automotive industry. In the proposed process, a laminated carbon woven fabrics with thermoplastic grains were heated, then transferred rapidly to a preheated mold for thermostamping, and cooled down to form the composite part. Various thermoplastics including polyamide 6, polypropylene, and acrylonitrile butadiene styrene were used as matrix materials. It is demonstrated that high-quality parts can be achieved with the proposed forming process and defects are controllable. The experiment results show that the rheological characteristics of thermoplastic resin, the fixed method of mold, and the yarn orientation of the composite blank are very important factors in the thermostamping process. With the proposed process, it is feasible to implement the high-volume and low-cost manufacturing of fiber-reinforced composite parts.

Ultrafast Feed Drilling of Carbon Fiber-Reinforced Thermoplastics

“…However, the cost of epoxy is relatively high, and a typical production process of resin transfer molding has a longer takt time than injection molding and press molding [3]. Hence, carbon fiber-reinforced thermoplastics (CFRTPs) have attracted attention, although the issue of lower heat resistance remains.…”

Investigation on influence of stamp forming parameters on formability of thermoplastic composite

“…Lee et al [14] did analysis of the impact of blank holding force on the shapes formed on non-crimp fabrics during the stamp forming process. Many researchers have done experimental and numerical formability analyses for woven fabric reinforced polymer composites [15][16][17][18] .…”

Selectively Enhanced 3D Printing Process and Performance Analysis of Continuous Carbon Fiber Composite Material

“…Carbon fiber (CF) is a new type of 3D printing material. The CF 3D printing products can have excellent performance and light weight characteristics compared to metal materials [5,6]. The traditional manufacture of carbon fiber models is mostly formed by different molds under a certain temperature and pressure.…”
