Breakthrough in new carbon fiber composites develo

DuPont's research and development of new carbon fiber composites has been outstanding, so the new carbon fiber composites show a more playful performance than traditional textile materials, especially in the preparation process, showing good fabric formability

DuPont made a breakthrough in the research and development of new carbon fiber composites

on May 15, the American advanced composite manufacturing innovation Association (iacmi, Knoxville, Tennessee, USA) is a joint public and private organization aimed at accelerating the development of composite materials and processes in the United States. The Association announced that DuPont The first phase of the study was completed by a project collaboration from fibrtec (Atlanta, Texas, USA) and Purdue University (Wilmington, De, USA). The conclusion of the first stage verifies that compared with traditional textile materials, the preparation of new carbon fiber composites shows good fabric formability. The results of the first phase promote the second phase of the project, and may reduce the cost of carbon fiber composite structures, making them more suitable for large-scale adoption in automotive and other industries

the new materials developed through this iacmi project combine fibrtec's flexible coating tow, fibrflex, DuPont's rapid fabric forming (RFF) technology and proprietary DuPont polyamide resin, which are carried out with the support of Purdue University's modeling and characterization capabilities. The coated tow material is a partially impregnated carbon fiber and polyamide composite tow, in which the carbon fiber is not completely wetted by polyamide, resulting in a softer tow material than the fully impregnated fiber. RFF process is a method of manufacturing fabrics with tow in different directions without lifting the tow during processing. It is reported that experiments, modeling and simulation show that this process and material combination method is a potential method to produce low-cost continuous fiber reinforced polymer (CFRP) thermoplastic materials, which meet the requirements well in the molding process

iacmi CEO John Hopkins said: "Through the research in the second phase of this project, we will more comprehensively describe the forms of this new carbon fiber thermoplastic prepreg, and verify that they are very suitable for high-speed, cost sensitive molding processes. This will show whether they are suitable for large-scale applications, especially in the automotive industry, which is an important part of our long-term goal of reducing energy use.
