China Unidirectional glass fiber tapes from Hanyao supplier is a high-strength, non-woven fiberglass binding material widely used in motor manufacturing and repair. It consists of parallel-arranged fiberglass filaments impregnated with a special resin (usually epoxy or polyester resin).Simply put, it is a "high-tech rope" used to bind, fix, and reinforce the rotor or stator windings of an electric motor.At the rotor end of high-speed motors (such as steam turbine generators and large electric motors), the windings are subjected to enormous centrifugal forces. Unidirectional glass fiber tape forms a robust whole, replacing traditional metal retaining rings, preventing the windings from being thrown out or deformed under high-speed rotation.By binding, the dispersed coils are tightly bonded to the iron core, improving heat dissipation, mechanical strength, and operational stability. Unidirectional glass fiber tape itself has good insulation properties and can be used as supplementary insulation to improve the insulation level between windings.
| 1 | Type of glassfiber | E-glass | Most commonly used, with good insulation, mechanical strength and heat resistance. |
| S-glass | It has higher strength and is used in applications with extremely high mechanical performance requirements (such as ultra-high speed motors). | ||
| 2 | Resin type | Epoxy resin | Most commonly used, with high bonding strength, low curing shrinkage, excellent electrical properties, and good chemical resistance |
| Polyester resin | It has a lower cost and faster curing time, but its heat resistance and bond strength are generally lower than those of epoxy resin. | ||
| Modified resins | such as special modified resins that are resistant to high temperatures, have good toughness, or are fast-curing. | ||
| 3 | Sizes | Width | 10mm, 15mm, 20mm, 25mm, 30mm |
| Thickness | 0.15mm ~ 0.30mm | ||
| 4 | Tensile strength | MPa | ≥800 |
| Elastic modulus | Gpa | 30-50 | |
| Density after curing | g/cm³ | 1.8 - 2.2 | |
| 5 | Heat resistance grade | 130℃,155℃,180℃ | |
| Breakdown voltage | kV/mm | ≥20 | |

1.The glass fiber has extremely high tensile strength, and after binding, it can withstand enormous centrifugal force and mechanical stress.
2.Thermosetting resin, after being heated or cured at room temperature, permanently hardens the binding layer into a rigid, irreversible, and extremely stable whole.
3.These unidirectional glass fiber tapes is non-magnetic, made of glass fiber and resin, does not generate eddy current losses, does not increase the iron loss of the motor, and has high efficiency.
4.It has good electrical insulation properties, and depending on the resin used, it can achieve different heat resistance grades (such as B, F, and H grades).
5.It is mainly used in motors and electrical appliances requiring high speed and high reliability
