ABSTRACT:
A continuous structural laminate includes a plurality of continuous generally parallel spaced integrally bonded porous blankets with a continuous polymeric matrix extending through each porous blanket. The polymeric matrices include solidified polymeric mixtures with each mixture including a polymer forming material, a gas foaming agent, a catalyst and a major portion of a particulate reinforcement. The polymeric matrices include compatible polymer forming materials. At least two of the blankets include polymeric matrices with differing particulate reinforcements. The continuous structural laminate is formed and applied with mobile apparatus including a support portion, a raw material supplying portion, a mixing portion, a matrix forming portion and a control portion. The support portion includes at least two base sections with carriages depending from a first base section including a plurality of spaced transverse axle assemblies and wheels mounted on free ends of each axle assembly. A boom section extends from the first base section with transfer mechanism selectively moving a second base section along the boom section. The raw material supplying portion includes a plurality of reservoirs disposed on the first base section. A blanket support also is disposed on the first base section. The mixing portion, matrix forming portion and blanket combining mechanism are disposed closely adjacent to the second base section and movable therewith.
