Castro Composites offers you a wide catalogue of fibre reinforcements, ranging form the more economic glass chopped strand mats to technical multiaxial glass fabrics, carbon fabrics, aramids (mainly Kevlar), high-molecular weight polypropylene fabrics (Innegra), natural fabrics (flax), as well as combinations of these materials.

Reinforcement usually adds stiffness, resistance and greatly impedes crack propagation. Thin fibres can have very high strength, and provided they are mechanically well attached to the matrix they can greatly improve the composite's overall properties. The right combination bettween fabric and matrix is essential for achiving a long lasting composite.

Fiber-reinforced composite materials can be divided into two main categories normally referred to as short fiber-reinforced materials and continuous fiber-reinforced materials. Continuous reinforced materials will often constitute a layered or laminated structure. The woven and continuous fibre styles are typically available in a variety of forms, being pre-impregnated with the given matrix (resin), dry, uni-directional tapes of various widths, plain weave, twill weave, harness satins, braided, and stitched (multiaxials).

The short and long fibers are typically employed in compression moulding and sheet moulding operations. These come in the form of flakes, chips, and random mate (which can also be made from a continuous fibre laid in random fashion until the desired thickness of the ply / laminate is achieved).

  • Aramid (Kevlar)

    Aramid fibers are a class of heat-resistant and strong synthetic fibres. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in bicycle tires, and as an asbestos substitute. The name is a portmanteau of "aromatic polyamide". They are fibres in which the chain molecules are highly oriented along the fiber axis, so the strength of the chemical bond can be exploited.

  • Carbon

    Reinforcement fibres known thanks to its low specific gravity, high resistance and great stiffness. Its more famouse precusor is PAN (polyacrylonitrile). Carbon fibres are obtained by pyrolisis at temperatures higher than 980 ºC.

    The main properties of carbon fibres are the following: high Young modulus (stiffness), excellent tensile strength, electrical conductivity, great fatigue resistance, high weathering resistance and a very low CTE (Coeficient of Thermal Expansion). The very low CTE property makes these fabrics the best choice for the production of composite parts and tools produced in the oven (prepregs) at high temperatures.

    Care must be taken when installig carbon composite parts together with metals as they favour galvanic corrosion of the metal. Aluminium, iron or steel must not be used. Titanium is the best choice in these cases.

  • Glass

    Glass fiber has roughly comparable mechanical properties to other fibers such as polymers and carbon fibre. Although not as strong or as rigid as carbon fiber, it is much cheaper and significantly less brittle when used in composites. Glass fibers are therefore used as a reinforcing material for many polymer products; to form a very strong and relatively lightweight fibre-reinforced (FRP) composite material called glass-reinforced plastic (GRP), also popularly known as "fiberglass". This structural material product contains little or no air or gas, is more dense, and is a much poorer thermal insulator than is glass wool.

  • Hybrid
  • Carbon Imitation
  • Innegra

    Innegra™ HMPP (high molecular weight polypropylene) is a high performance fiber used in composite and textile applications which can be converted into many different reinforcements.

    Benefits of using Innegra are: light weight (0.84 g/cc), durable, minimizes catastrophic failure, ductile, impact resistant, vibration damping, excellent dielectrics, low elongation, highly crystalline, hydrophobic, energy dissipation and recyclable.

  • Natural
  • Basalt

    Basalt is the most common volcanic rock type on earth, being a key component of oceanic crust as well as the principal volcanic rock in many mid-oceanic islands.

    Basalt fibers consisting of filaments, continuously extruded from the high temperature melt of carefully selected basalt stones with a diameter of 10 µm and higher, are well above the limit of 5 µm for being respirable.

    Basalt fibers products demonstrate following properties:

    • Natural, low ecological footprint
    • Unique fire and heat performance
    • Excellent mechanical properties
    • Great chemical resistance
