Chopped Carbon Fiber

Gateway Composites provides chopped fibers in multiple product forms to accommodate compounding and wet or dry batch mixing.

Feed-ability – Excellent bundle integrity with high bulk density means consistent feed rates with no nesting or bridging.

Chemical Compatibility – Sizing chemistry that works with the matrix resulting in proper filament dispersion and adhesion.

Product Consistency – Batch to Batch consistency in properties.  In-line process controls confirmed by in-house lab testing.

Application Specific Products – Fiber length, mechanical properties, electrical properties and sizing chemistry options available for the customer’s specific CTQs (critical to quality) characteristics.

Technical Support

Gateway Composites’ products are engineered with the understanding of what is important to the processor and the end user.  We can satisfy your needs whether your application is electrical, mechanical, thermal or friction related.
