Long Fiber Composites Molding Compounds

  • Overview

    SBHPP Engineering long fiber composite materials are obtained by powder or liquid impregnation of continuous or chopped fiber. Our Long Fiber Composites are suitable for compression or injection molding.
    Fiber reinforcement lengths range from 3 mm to 24 mm (and even more on request). Increased fiber lengths boost product performance in tensile and flexural strength as well as impact resistance. For Aerospace applications, FST Grades are also available to meet FAA OEM Heat Release requirements.
    Porophen®, Neonit®, Kinel® and DuraPEKK® are long fiber grades produced within a specific patented 'solvent free' process.

    • Long Fiber Phenolic Composites

      Porophen® Phenolic composites offer outstanding dimensional stability, resistance to creep under dynamic and static loads at elevated temperatures. Phenolic is the matrix of choice for Fire Smoke Toxicity (FST) superior properties in Aerospace & Transportation industries.

    • Long Fiber Epoxy Composites

      Epoxy is the matrix polymer of choice to use in structural composite materials. No other polymers can better optimize the properties of reinforcement fiber such as carbon, glass, aramid, etc.

      Long Fiber Epoxy Molding composites are available in two main types:

      Neonit® series materials; impregnated within a patented solvent free process

      E and EM series materials; High performance grades glass fiber reinforced.

      Kinel® Polyimide (BMI) composites are well known for their very high thermal stability & resistance, and for their excellent mechanical properties associated with a good chemical resistance.

    • Poly-Ether-Ketone-Ketone (PEKK) long Fiber Composites

      DuraPEKK® long fiber composites are semi-crystalline thermoplastic matrix composites that exhibiting very high thermal resistance, excellent mechanical and chemical resistances.

    • Long Fiber Phenolic composites

      Porophen® materials are molding composite based on phenolic matrix and long carbon or glass fiber as reinforcement. The high cross-linked structure phenolic matrix polymer (after molding) shows a superior chemical resistance against almost all aggressive fluids, even at high temperature.

      Porophen® series materials are long glass or carbon fiber reinforced phenolics. They are free of solvents and easy to transform. Fiber reinforcement lengths range commonly from 3 mm to 12 mm. Increased fiber lengths boost product performance in tensile and flexural strength as well as impact resistance. Porophen® materials offer outstanding mechanical properties, dimensional stability, and creep resistance under dynamic and static load at high temperatures.

    • Long Fiber Epoxy composites

      SBHPP Long Fiber Epoxy materials are molding composite based on epoxy matrix and various long fiber as reinforcement. Epoxy is the matrix polymer of choice to use in structural composite materials. No other polymers can better optimize the properties of any reinforcement fiber. Epoxy resin is also known for its excellent electrical insulation properties combined with a high retention of characteristics at elevated temperatures.

      Long Fiber Epoxy Molding composites are available in two main types:

      • Neonit® series materials; impregnated within a patented solvent free process

      • Neonit® Long Fiber Epoxy molding composites

        Neonit® series materials are long glass or long carbon fiber reinforced epoxies. They are free of solvents and easy to transform. Fiber reinforcement lengths range commonly from 3 mm to 8 mm (even more on demand). Increased fiber lengths boost product performance in tensile and flexural strength as well as impact resistance.

        Key properties:

        • Superior electrical insulation properties; Neonit® materials provide superior electrical insulation properties (except materials with conductive filler such as carbon or graphite) such as electric strength and CTI (up to 600kV/mm) from low to high temperatures (up to 180°C).
        • Dimensional stability; Neonit® parts can be molded in very tight tolerances thanks to very low molding shrinkage, the length of the fiber reinforcement and three dimensional network of the epoxy resin matrix obtained after in-mold curing.
        Application example:
        Industrial - Electrical explosion proof housing made with Neonit® Long Glass Fiber Epoxy material.
      • E & EM series Long Fiber Epoxy molding composites

        E & EM series materials are long fiberglass or polyaramide reinforced epoxy molding compounds, which feature high strength and toughness for structural components. These grades are suitable for compression or transfer molding.

        Key properties:

        • High strength and toughness.
        • Impact strength.
        • EM 7302 is designed for applications requiring Mil-M-46069 certification
        Application example:

    • Long Fiber Polyimide (BMI) composites

      Kinel® High Performance Polyimide (BMI) molding compounds are based on polybismaleimide thermoset resins. Polyimide (BMI) plastics are well known for their very high thermal stability & resistance, and for their excellent mechanical properties associated with a good chemical resistance. Kinel® products are long fiber reinforced molding polymers offering a wide range of high class properties from cryogenic to very high temperatures. Common fiber reinforcement lengths range from 3 mm to 12 mm. Increased fiber lengths boost product performance in impact resistance as well as in tensile and flexural strength. They are free of solvents and easy to transform.

      Molding compounds are reinforced with glass or carbon fiber.


      Key properties:

      • Kinel® polyimide (BMI) composites have high flexural strengths and modulus. They exhibit very low creep and have excellent impact and notched impact strength. These properties are maintained during continuous exposure from low (-50°C) to very high temperatures (200-230°C) and even, for very short duration, as high as 450°C.
      • Kinel® polyimide grades exhibit excellent radiation resistance (up to 1010 rads)1 and consequently are able to be used in nuclear industry.
      • Parts are not affected by common oils and solvents including hydrocarbons, esters, ethers and alcohols. They also resist weak acids but are not recommended for use in alkalis or inorganic acids environments.
      • Kinel® parts can be molded in very tight tolerances thanks to the low molding shrinkage and the length of the fiber reinforcement.
      • Good electric insulation properties2 are maintained from low to high temperatures (up to 200°C).
