Thermoplastic composite materials

Composite solutions have already become integral to numerous applications due to their outstanding properties. They are used wherever high mechanical, chemical, and thermal demands must be met with minimal weight – from aerospace and infrastructure to energy, medical technology, and consumer goods such as sports equipment.

Many applications use thermoset composites with glass or carbon fibres. While offering beneficial mechanical properties, they can't be reshaped or welded and are difficult to recycle. In this context, thermoplastic composite materials – fibre-reinforced plastics with a thermoplastic matrix – offer numerous advantages.

As a leading manufacturer of high-performance thermoplastic materials, we develop and produce tailor-made composite solutions precisely matched to your requirements. Fibre type, fibre architecture, and fibre volume content, as well as the thermoplastic matrix material used, can all be configured for the specific application. In addition to carbon and glass fibres, alternative reinforcement materials such as aramid, basalt, or natural fibres are available. We also offer a wide range of thermoplastic matrix materials, from commodities such as polypropylene to high-performance plastics like PEEK.

All process steps are carried out entirely in-house. This not only ensures stable production conditions and reliable scalability but above all: maximum flexibility. We step in where existing solutions reach their limits. Thanks to our agile manufacturing structure, we offer rapid adjustments, efficient prototyping, and a significantly shortened time-to-market – even for demanding series projects.

Step 1: Choosing the thermoplastic matrix material

The matrix is the central binding element in a composite material. It holds the fibres together, determines the shaping process, and significantly influences the chemical, thermal, and mechanical properties of the material. Do you have specific requirements such as temperature resistance, flame retardancy, surface quality, or design freedom? We offer the right polymer solution for your project. We also take into account the special conditions of your industry, offering materials that already meet relevant standards and approvals – for example, in medical technology, aerospace, and sport.

Step 2: Selecting the reinforcing fibre & fabric type

The reinforcing fibres are responsible for the mechanical performance of the thermoplastic composite material. The fill ratio can influence strength, weight, and impact resistance. In addition, the appropriate fabric structure affects processing and formability. Alongside glass fibres and carbon fibres, our portfolio also includes synthetic fibres such as aramid, as well as natural fibres such as flax.

    • Basalt: Natural, heat-resistant & robust – ecological and functional
    • Flax: Sustainable fibre with good stiffness – ideal for “green” applications and design components
    • Special fibres on request

Step 3: Selecting the right processing stage

Whether prepreg, semipreg, organosheet, or plate – we deliver the composite solution that suits your processing environment and production logic. This saves time, minimises material waste, and optimises your value creation. Depending on the application, you can choose whether semipreg, prepreg, organosheet, or plates are the right intermediate product. Our experts are also happy to provide tailored advice.
  • Pre-impregnated fabrics for efficient further processing

    The semipreg production process begins with grinding the plastic granules into powder with tight tolerances on the final particle size. The powder is then applied to the fabric in the semipreg plant and melted onto the fabric. The resulting intermediate product is called semipreg. If the semipreg is subsequently processed using a double-belt press which fully impregnates and consolidates the material, it is then referred to as a prepreg. We manufacture thermoplastic semipregs and prepregs in the various polymer and fabric combinations listed above.

  • High-performance sheets for structural applications

    An organosheet is a multilayer construction of pre-impregnated fabrics that are consolidated. Our thermoplastic organosheets are produced from semipreg material or using the film-stacking process, with components individually matched to your application. With a working width of up to 1,300 mm, the double-belt press processes not only our in-house thermoplastic semipregs but also unidirectional (UD) materials, UD cross-ply materials, laminates, and sandwich laminates with various core materials such as foam or honeycomb.

  • Custom dimensions for precise manufacturing

    Plates made from thermoplastic fibre-reinforced plastics can be supplied in thicknesses from 1 mm to 55 mm in sizes up to 1,200 × 900 mm, and in thicknesses up to 95 mm in sizes of 500 × 600 mm. Most thermoplastic matrix materials are available.

WHY YOU SHOULD USE THERMOPLASTIC COMPOSITES FROM ENSINGER

With our thermoplastic composites, we offer you tailor-made materials that can significantly advance your projects. Thanks to the modular material selection – from the matrix to the fibre to the construction – the properties can be precisely matched to your application. This makes our materials the ideal solution for a wide range of uses, even for the most demanding high-end applications.
Due to their re-meltability, they are also recyclable, helping to reduce the CO₂ footprint. Thanks to their advantageous property profile, they offer clear benefits over conventional thermosets, metals, or short fibre-reinforced plastics – both ecologically and functionally.
  • Combinations of matrix, fibre, fabric type, and structure can be precisely tailored to your application.
  • Unlike thermoset composites, which cannot be reused after curing, thermoplastic composites can be recycled by melting and shredding, enabling resource-efficient material use.
  • Thermoplastic fibre-reinforced plastics offer mechanical properties at almost metallic levels despite their low weight – especially when using continuous oriented fibres – achieving:

    • Five times higher tensile strength compared to unreinforced polymer sheets
    • Five times higher modulus of elasticity
    • Density of only 1.3–1.8 g/cm³, comparable to unreinforced or short fiber-reinforced plastics
    • Similar stiffness and strength to metal at significantly lower weight
  • With their high impact resistance and damage tolerance, thermoplastic composites are particularly well-suited to applications in harsh environments; their high elongation at break ensures tough, non-brittle fracture behavior.
  • Thermoplastic composites retain their mechanical properties even at elevated temperatures. They remain stable and reliable in demanding thermal environments. Continuous fiber-reinforced thermoplastics in particular exhibit extremely low coefficients of thermal expansion (approx. 5 × 10⁻⁶ K⁻¹), making them ideal for precision-critical applications with large temperature fluctuations.
  • Compared to unreinforced or short fibre-reinforced polymers, continuous fibre-reinforced materials have significantly higher creep resistance and improved fatigue behavior.
  • Thermoplastic fibre-reinforced plastics exhibit excellent vibration damping thanks to their inherent damping properties. This can be particularly advantageous in applications where vibration needs to be filtered.


Processing advantages for thermoplastic composite materials

  • Fast & automatable processing: Thermoplastic composites require no chemical curing, reducing cycle times to just minutes and enabling high-volume automated production with consistent quality.
  • Stable & easy to handle: They can be stored and transported at room temperature and have virtually unlimited shelf life.
  • Versatile post-processing: When heated, they soften, making them formable and weldable.
  • Recyclable & emission-free: Being solvent-free, they release no VOCs during processing.

Orthopaedic Trauma Internal Fixation Systems

The goal of orthopaedic trauma treatment is to restore a broken bone to its correct position and orientation. When this is done by means of surgical intervention, fixation systems are used to secure the bone in the anatomically correct position. Manufacturers of such internal fixation systems need to meet many and exacting requirements in terms of function, weight and appearance, at the same time as keeping an eye on the overall costs in view of increasingly tight budgets.
