A Response Surface for the Complex Modulus of Composite Materials

Abstract

The complex modulus of boron/epoxy and graphite/epoxy laminates has been measured in forced vibration tests at frequencies rang-ing from 20 to 17, 000 Hz and temperatures varied between -50^ and +300^F. The data was analyzed using response surface methodo-logy. Based on the response surface time- temperature shift para-meters, master curves, and probability relations have been developed.
