COMPOSITE ANALYSIS

Composites Maximize Design Potential

Quartus has extensive experience in the analysis of composite structures. Areas of expertise include:

Materials

  • Unidirectional tape, fabric, 3-D woven
  • Bulk and sheet molding compounds
  • Graphite, fiberglass, kevlar
  • Matrix materials (epoxy, CE, BMI)

Manufacturing Methods

  • Laminates (prepreg, RTM, VARTM)
  • Filament winding
  • Pultrusion

Lunar Reconnaissance Orbiter Camera

Analysis-Driven Design

  • Laminates
  • Sandwich panels (aluminum, kevlar, nomex honeycomb, foam)
  • Bulk molded components

Optimization

  • Laminate thickness
  • Ply orientation
  • Min. weight, min. frequency, stiffness

Loading

  • Static
  • Dynamic (transient/shock/vibration)
  • Thermal (distortion, dimensional stability, thermal stress)
  • Hygroscopic

Software Tools
