PROBLEM TO BE SOLVED: To solve the problem that transparent sheets and boards of amorphous PET (A-PET) have a blemish of low added value as they are vulnerable to fine scratch (low scratch resistance) and easy to get dusty due to surface softness, and require market cultivation especially in high added value applications like interior goods, illumination tools and building materials. SOLUTION: The invention is a manufacturing process of non-woven fabric sheets and board lamination, and heat process shaped goods by melting a polyethylene terephthalate type polyester (a) at a temperature above its fusing point in an extruder, and melt bonding it to a non-woven fabric (c) having 50-250 g/m<SP>2</SP>basis weight ratio of the same material, while fabricating into amorphous sheets and boards (b) by casting method.
