Fiber Tech Pultrusion Products
We offer a wide range of pultrusion products for the Pultrusion process. Pultrusion is a continuous, automated closed-moulding process that is cost effective for high volume production of constant cross section parts. The basic process usually involves pulling of continuous fibers through a bath of resin, blended with a catalyst and then into pre-forming fixtures where the section is partially pre-shaped & excess resin is removed. It is then passed through a heated die, which determines the sectional geometry and finish of the final product.
Due to uniformity of cross-section, resin dispersion, fiber distribution & alignment, excellent composite structural materials can be fabricated by pultrusion. The profiles produced with this process can compete with traditional metal profiles made of steel & aluminium for strength & weight.
By using various additives, liquid resin systems can be made suitable to provide specific performance. Alumina trihydrate is filler that is used for its ability to suppress flame and smoke generation. Special purpose additives include ultraviolet radiation screens for improved weatherability, antimony oxide for flame retardance, pigments for coloration, and low-profile agents for surface smoothness and crack suppression characteristics.

Thermal conductivity of composites is affected by both matrix and fibre characteristics. Generally, the glass & organic fibre reinforced composites are excellent insulators for thermal and electrical environments. The use of conductive carbon fibres, however, results in composites that exhibit thermal and electrical conductivity to some extent; this reduces their effectiveness as insulators but creates opportunities because of their static charge and heat dissipation characteristics.
Specific gravity is a key consideration when strength-to-weight ratios are important as in aircraft and aerospace applications. Carbon and aramid-reinforced composites excel because of their low specific gravities and high strength & stiffness characteristics.
The impact resistance of organic fibre reinforced composite is quite high, making them suitable for energy absorption applications. Fibre glass-reinforced composites are relatively poor in impact performance compared to organic fibres, but are superior to carbon-reinforced composites. Composites using carbon fibre rely on the toughness of the resin matrix for impact properties.
Chemical & Corrosion resistance characteristics of pultruded composites are attributed to the properties of resin used. Chemical & corrosion attack can occur at the product surface or at the end. The presence of a resin rich barrier layer on the surface provides greater degree of corrosion resistance. To achieve a resin-rich surface, a synthetic veil or mat, typically of polyester fibre, is used on the surface of the products when pultruded. The layer can range from 0.15 to 1.00 mm thick, depending on the thickness of the material used. The end cut of the profile is particularly vulnerable to corrosion because fibres are exposed to the environment. Therefore, it is a common practice is to dip-coat the end cuts of pultruded profile to seal them from corrosive attack. If this is not done, the corrosion resistance of the fibre itself becomes an important consideration because the resin does not effectively protect the fibre from attack along the fibre-resin interface at open ends.
