A passenger side airbag door for instrument panel includes a substrate with airbag opening, skin layer and foam layer, a PAB door reinforcement board which covers the airbag opening is connected to the instrument panel substrate. This PAB door reinforcement board is a cellulosic composite material board which is soaked by thermoplastic plastic or thermoplastic elastomer, formed through thermoforming.
