A method of forming a continuous structure includes the steps of flowing a first liquid reactive resin forming material over a base surface, forming a first thin substantially uniform layer thereof and gelling the first layer. A second liquid resin forming material is flowed through an orifice under pressure forming a liquid stream thereof. The liquid stream is gelled to form a continuous filament with structural integrity as it advances toward the first gelled layer. The filament is contacted with the first layer and distributed thereover in a preselected pattern forming a porous non-woven filament blanket. A particulate solid material is distributed substantially uniformly over the filament blanket. A third liquid resin forming material is flowed over the blanket forming a second thin substantially uniform layer of the third liquid resin forming material and the layer is gelled. The resulting freshly formed structure is compressed and positioned in a final configuration while the structure is flexible and adhesive after which curing is completed. Also, apparatus forming the structure as well as the structure itself.
