Document Type and Number:

Japanese Patent JP2001316499

Kind Code:

A

Abstract:

To provide laminated sheets having good flame retardance and heat resistance without using a halogen based flame-retardant, a phosphorus based flame-retardant and a nitrogen based flame-retardant.

A prepreg to be used is obtained by impregnating an inorganic fiber nonwoven fabric containing 40-90 wt.% metal hydroxide with a varnish using a resin composition containing a thermosetting resin as the essential component and none of a halogen based flame-retardant, a phosphorus based flame-retardant and a nitrogen based flame-retardant and drying the impregnated fabric.
