The resin *impregnated* glass cloth that is partially cured is called
"prepreg". Multiples of sheets of prepreg are sandwiched between cores
during lamination; under temperature and pressure they melt and resolidify
to *bond* the individual cores together into the multilayer PCB. Prepreg is
also sometimes called "b-stage" (as in "bonding").
