F-22 & JSF – 20 mm Ammunition Cartridge Guides

Project Objective:

Develop two sets of complex parts with curved vertical walls that form the channels through which ammunition rounds travel. Also to match the thermal properties of the container’s carbon/epoxy pre-preg side panels and meet specific weight restrictions.

Lytex 4149 Carbon Fiber Epoxy Engineered Structural Composite offered superior wear resistance, compared to metals, and provided better vibration damping and fatigue resistance when jarred by ammunition rounds cycling at high speed through each guide.

Proven Results:

  • Lightweight
  • Design flexibility
  • Part count reduction
  • Reduction in secondary operations
  • Dimensional stability



Rifle Hand Guards

Project Objective:

A glass-reinforced hybrid polyester thermoset material was developed to provide an improved solution over the incumbent phenolic material. In addition to improved mechanical performance, a fiber flow and warpage problem was removed.

Proven Results:

  • Good impact strength
  • Low gloss finish
  • Lightweight
  • Fire resistant
  • Thermal management
