Material potential, engineered into products.
Thermoplastic fabric prepreg developed with CARO’s patent-related technology.

Thermoplastic Fabric Prepreg

Product definition

A flexible single-ply woven intermediate combining Carbon, Basalt or Glass fabrics with Elium® acrylic thermoplastic resin. The fully polymerized, tack-free prepreg is supplied in rolls for subsequent layup and heated consolidation.

KEY FEATURES & BENEFITS

Key Features & Benefits

Flexible single-ply roll supply

Flexible woven prepreg is supplied in rolls for layup and continuous feeding.

Tack-free handling

Fully polymerized, tack-free supply supports convenient handling and layup.

Lightweight structures and strength

Fiber reinforcement and layup design support lightweight structures with the strength and stiffness required for the application.

Reprocessing and reforming

Thermoplastic resin enables subsequent forming and reforming to be considered under appropriate heating conditions.

Impact and damage performance

Fiber, resin and layup choices can address impact and damage requirements. Performance is verified for the specific application.

Chemical resistance and service temperature

Resin and structural choices are reviewed for suitability under chemical exposure and service-temperature conditions.

Recycling and repair possibilities

Thermoplastic materials support consideration of recycling, reprocessing and repair routes, selected according to the product structure and conditions.

Manufacturing and forming efficiency

Already polymerized prepreg is heated and consolidated into products, with routes to continuous consolidation and press forming.

Customization for the application

Carbon, Basalt and Glass materials, plain and twill fabrics, thickness and layup are reviewed for the intended product.

Cost efficiency

Material use, layup, manufacturing processes and automation are considered together to improve development and production cost efficiency.

Actual performance and benefits depend on materials, layup, processing and the service environment. Numerical and comparative performance will be added when product-specific test data are available.

THERMOPLASTIC ADVANTAGES

How CARO differs from thermoset materials

Less expiry management · Shorter subsequent forming · Continuous production and automation

ComparisonCARO thermoplastic prepreg / laminateTypical thermoset prepreg / laminate
Storage and expiryFully polymerized solid prepreg requires no refrigerated or frozen storage and has no expiry caused by the progress of uncured-resin curing.Uncured prepreg requires resin-specific shelf/out-life management and may require cold storage. The same uncured-resin expiry concept does not apply to fully cured laminate.
Subsequent forming principleAlready polymerized material is heated, consolidated/formed and cooled, without waiting for a separate resin cure at this stage.Prepreg layup requires chemical resin curing; post-curing may be included depending on the system.
Processing timeEliminating the cure wait in subsequent forming supports shorter cycle design. Actual time depends on thickness, heating and cooling.Cure time and sometimes post-cure time are required. Rapid-curing thermoset systems also exist; comparisons must be process-specific.
Continuous production and scalabilityRoll-prepreg feeding, continuous CCM laminate manufacture, automatic cutting and press automation support repeatable production.Cure conditions and material out-life must be incorporated into planning. Thermosets can also support automated, continuous and high-volume processes.
Inventory and handlingAvoids cold-storage and thawing requirements; tack-free handling supports storage, feeding and layup.Prepreg may require cold-chain logistics, thawing and out-time tracking. Cured laminate follows separate handling requirements.
Thick laminatesNo cure exotherm must be controlled during heated consolidation. Thick sheets are reviewed in a separate press for heat transfer, pressure and cooling.Cure exotherm and heat transfer inform the cure schedule. Thick sheets are possible, with appropriate process control.
Changes after formingReheating and reforming can be considered under material- and structure-appropriate conditions.Cured resin is difficult to reform through reheating in the manner of a thermoplastic.
RecyclingThermoplastic behavior supports consideration of reprocessing and recycling routes.The cured crosslinked matrix does not readily remelt; separate recycling routes are required.

The expiry statement applies to already polymerized CARO products, not to the storage life of liquid Elium® resin before manufacture. Moisture, contamination, UV and heat exposure remain storage considerations. Guaranteed storage period and quantified cycle time/output: [ ]. Comparisons describe general principles and depend on the resin and process.

IMPREGNATE FIRST · POLYMERIZE IN PLACE

How in-situ polymerization impregnation benefits prepreg

Impregnate in a low-viscosity liquid state, then form the thermoplastic polymer within the fabric.

  1. 01Fabric feeding
  2. 02Low-viscosity liquid impregnation
  3. 03In-situ polymerization
  4. 04Winding polymerized prepreg
  5. 05Cutting & layup
  6. 06Heated consolidation & cooling
01

Low-viscosity impregnation into the fibers

Liquid acrylic thermoplastic resin impregnates the fabric first, reducing the impregnation challenge associated with highly viscous polymer melts. This approach supports control of wetting within fiber bundles and resin distribution.

02

Polymerization within the fabric

The impregnated resin is polymerized within the fabric to form a solid thermoplastic matrix. Connecting low-viscosity impregnation with polymer formation is the core of the process.

03

A flexible, tack-free intermediate

Fully polymerized fabric prepreg is handled as a flexible single-ply intermediate and supplied in rolls. Customers can cut and lay it up for subsequent heated consolidation.

04

Reduced cold-storage requirements

As an already polymerized solid prepreg, it avoids uncured thermoset cure-related expiry management and cold-storage requirements. Storage-environment controls and a formal guaranteed period remain separate considerations.

05

From continuous manufacture to continuous forming

Fabric feeding, impregnation, polymerization and winding connect in a continuous manufacturing workflow. Supplied rolls can then feed multi-ply CCM, linking material manufacture with laminate consolidation.

06

Shorter downstream forming workflow

Polymerization is completed before prepreg supply, allowing subsequent forming to use heating, consolidation and cooling. Polymerization during material manufacture and later thermoforming are distinct stages.
