Abstract
The present invention is to provide a base material for a laminate having a high strength, reduced thickness, and light weight. In the present invention, a base material is prepared by incorporating a thermosetting resin binder into a non-woven fabric of para-aramid fibers prepared by a wet type paper making, and then heating a plurality of the resultant non-woven fabric sheets under pressure. The non-woven fabric sheet comprises 95 to 70 mass % of the para-aramid fibers and 5 to 30 mass % of the thermosetting resin binder.
