Composite materials are materials that are composed of two different materials in order to blend their properties.

In the context of rocketry, this usually refers to glass, Kevlar, basalt, or carbon fibers embedded in a thermoset plastic resin.

Fiber types

Fiberglass

  • E-glass
  • S-glass

Kevlar

Basalt

Carbon

various different elastic moduli and tensile strength tradeoffs are available

Matrix Types

Polyester

Often used on boats. Rarely used for hobby rocketry.

Epoxy

Fiber layup arrangements

Filament winding

Unidirectional

Woven cloth

Nonwoven cloth

Resin application methods

Wet layup

used for filament winding: you dip the tow in resin before winding

Prepreg

Vacuum-assisted resin transfer

Compression methods

Sandbags

Vacuum bagging

(applies to VARTM too)

Heat shrink tape and tube
