ABSTRACT:
A method for making a reinforced fibrous mat having a net layer between two fibrous layers and the reinforced fibrous mat made therefrom is disclosed. The net layer improves handleability of the fibrous mat. The fibrous mat may be used as is or it may be molded to form a molded product. A thermoplastic binder such as latex or starch is used in forming the fibrous layers. A thermoset binding agent such as a phenolic resin is added to the fibers if the reinforced fibrous mat is molded.
