Unidirectional fabric production line-Prepreg Machine

Unidirectional fabric production line-Prepreg Machine

Kuntai prepreg machine adopts stable mechanical operation rolls and profiled devices to evenly spread wire, use resin glue to soak and carry film or release paper to adhere and solidify, and then dry and roll it at the rear end. This product has the advantages of low density, abrasion resistance, impact resistance, cutting resistance and toughness. It is widely used in special protective materials such as soft bulletproof jackets, light bulletproof helmets, light bulletproof armor plates, stab and cut resistant clothing linings, and special public anti riot facilities

Machine advantages

It adopts stable mechanical operation rolls and profiled devices to evenly spread wire, use resin glue to soak and carry film or release paper to adhere and solidify, and then dry and roll it at the rear end.
Versatility and Precision: Engineered to handle both UHMW-PE and UD Aramid fabrics, the machine guarantees lamination with impeccable uniformity, free from deformation, blistering, or wrinkles.
Advanced Lamination Technology: Utilizes stable mechanical components and an ultrahigh-pressure system for even wire spreading and resin impregnation, followed by orthogonal 0/90º composite lamination.
Smart Control System: Equipped with an HMI+PLC interface, simplifying operation and boosting production efficiency while minimizing manual intervention.
Starting with the precise unwinding of tubular ultra-high molecular weight polyethylene fibers, our machine meticulously guides each step of the process flow.
• Yarn Unwinding & Bundling: Fibers are neatly arranged and bundled for uniformity.
• Warping & Spreading: Ensuring parallel alignment and tension for optimal flatness.
• Dipping/Coating: Precise resin application ensures consistent coverage.
• Film Covering: Coupled with PE bearing film for added strength and protection.
• Drying & Curing: Heat rollers evaporate solvents, solidifying the resin matrix.
• Guiding & Winding: Finalizing with neat winding, ready for further processing

Main working process

Main working process: From Yarn to Finished Cloth

Fiber rack→Arrange→Beam-warping→Exhibition silk →Soakage→Membranae tectoria →Desiccation → Tractive → Rewinding device

The ultra-high molecular weight polyethylene fiber is placed on the reel, rolled back to the bunching device and arranged in parallel. The parallel PE fibers after being grouped pass through the finishing device to form parallel and tight filament bundles. After the ribbon is unfolded, tension is applied to ensure the flatness of the ribbon. After the fiber is impregnated with the bonding device, the uniform filament bundles after the PE carrier film passes through the bonding device are reassembled, and the resin solvent is evaporated by the hot roller to solidify to form a unidirectional PEUD cloth.
