Abstract: A process and system are provided for introducing chopped and dispersed carbon fibers on an automated production line amenable for inclusion in molding compositions, including the debundling of many carbon fibers collectively forming a tow into dispersed chopped carbon fibers that form a filler that undergoes plasma treatment prior to ...
Fiber-Reinforced Plastics. Introduced over 50 years ago, composites are fiber-reinforced plastics used in a variety of products, applications and industries. While the term "composite" can apply to any combination of individual materials, Composites One focuses on fibers, primarily glass, that have been impregnated with a plastic resin matrix.
Sereebo is a sheet-form composite featuring a polyamide 6 (PA6) matrix reinforced with discontinuous/chopped carbon fiber (25 millimeters, 24K tow). The fiber bed has been described as being very well distributed, giving the material isotropic properties depending on how it's molded. The thermoplastic matrix provides many benefits.
