Celstran® CFR-TP - continuous fiber reinforced thermoplastic

EASY PROCESSING WITH OUTSTANDING MECHANICAL AND THERMAL PERFORMANCE

Celstran® CFR-TP – a continuous fiber-reinforced product with a thermoplastic matrix – is designed for increasingly demanding component requirements that filled or short fiber-reinforced thermoplastics are unable to meet and where metals are no longer an option.

Product Properties

• Low weight with high stiffness and toughness
• Excellent impregnation technology
• High performance dimensional, mechanical and thermal properties
• Superior chemical and corrosion resistance
• Eco-friendly processing, recyclability
• Wide range of resins, fibers and additives

Celstran CFR-TP uses a patented process to achieve high impregnation quality without fiber damage. Every single filament of the reinforcement fibers is wetted intensively in this process

Tapes and Forms

• Unidirectional tapes (4-, 6-, 8-, 10-inch and custom widths)

Nearly all types of semicrystalline and amorphous thermoplastic polymers are suitable as thermoplastic matrix materials, and can be combined with a wide range of fibers and additives to provide localized reinforcement where additional strength is needed.

Processing

• Automated tape lay-up/consolidation — winding and tape placement
• Press consolidation — double belt press, press consolidation and continuous press consolidation
• Fluid heat transfer under vacuum (Quickstep-patented process of Quickstep Technologies Pty. Ltd.)
• Partial reinforcement — injection-molding incorporation, compression-molding incorporation, extrusion incorporation
• Sandwich structures

Celstran® LFRT-long fiber reinforced thermoplastic

EXCELLENT MECHANICAL PROPERTIES AND LOW WARPAGE FOR METAL REPLACEMENT

Celstran® long fiber reinforced thermoplastics (LFRT) unite long fiber reinforcements with advanced thermoplastic resins for a combination of mechanical properties, impact, creep resistance and low warpage.

Incorporated fibers can be glass, carbon, aramid and stainless steels. Nearly all types of polymers are suitable as matrix material.

Product Properties

• Markedly higher mechanical properties
• High notched impact strength
• Reduced creep
• Very good stability over a broad range of temperatures and climatic conditions

It is produced by pultrusion technology — the long fibers are impregnated to deliver optimal reinforcement to the plastic matrix. Unlike conventional short-fiber reinforced materials, the longer fibers form an internal glass fiber “skeleton” that limits anisotropic shrinkage and greatly reduces warpage in parts.

Grades

• Matrix materials: PP, PA (further matrix materials on request)
• Glass fiber reinforced: fiber content 20 to 60 percent
• Carbon fiber reinforced
• Aramid fiber reinforced
• Stainless steel filaments for EMI and RFI shielding

Processing

• Injection molding
