Sedimentation of carbon fiber in resin
Problembeschreibung
Carbon fibers settle in the resin in short fiber composite materials, causing uneven distribution
Ursachenanalyse
The density difference between carbon fiber and resin is large (CF~1.8 vs resin~1.2); resin viscosity is too low
Lösung
Increase resin viscosity; accelerate curing to reduce sedimentation time; fiber surface treatment
Wichtigste Erkenntnis
Carbon fiber sedimentation causes composite material performance gradients
