About Flat Fibers

Composites are replacing metals and alloys in high-performance applications that require high material strength with heat and chemical resistance. The issue of warpage, however, is troublesome for engineers who wish to produce precision parts for sensitive applications. In injection molding, warpage is the bending, twisting, or bowing of the molded part. This distortion causes the molded part to deviate from design specifications.

Glass fiber has been widely used in FRP for its strength, resistance to heat and chemicals, nonflammability, and electrical insulation properties. Nittobo offers a range of chopped glass fiber strands with a flatter cross section. These flat fibers (FF) are produced using Nittobo’s proprietary technology. Nittobo flat fibers have an oval cross-section in contrast with conventional fibers that have a circular cross-section. Due to their unique geometry, Nittobo flat fibers offer some extremely useful benefits, in addition to reduced warpage, when used as a reinforcement material for injection molding.

Fillers, in powdered or flake form, have been used to reduce warpage in composite materials. These fillers sacrifice physical properties of the composite to reduce warpage. Fillers like Mica and glass flakes have a poor reinforcement effect due to their non-fiber like structure. Flat fibers, on the other hand, help reduce warpage while improving the reinforcement properties of conventional glass fiber.

Nittobo flat fibers reduce warpage without sacrificing physical properties

Nittobo flat fibers are available in two different flat ratios of 2 (2FF) and 4 (4FF). The flat ratio is defined as the ratio of the length of the major axis to the length of the minor axis of the oval cross section. A finer flat-fiber, with a flat ratio of 4 but smaller cross-sectional area, (Fine-FF) is also available for special applications.
