Short Fiber Compounds improve these physical properties over neat resins

  • Tensile and flexural strength
  • Tensile and flexural modulus (or stiffness)
  • Short-term temperature (HDT) resistance
  • Long-term creep and fatigue resistance

GlassGlass fiber is the most common additive used. It lowers warpage and reduces creep, particularly at higher temperatures. Glass fibers can vary in length and have a general diameter of 10 to 15 microns. Milled glass is approximately 1/32 inch (1.59 mm) long while chopped glass is between 1/8 and 1/4 inch (3.18 and 6.35 mm).

Mineral fillers may also be added to reduce warpage or material costs in glass filled compounds.

Depending on your application, structural compounds can include additional modifications for conductivity, impact resistance, wear resistance, flame retardance, and color.
