Abstract
Abstract A resinous material suitable for the fabrication of laminated structures comprising a first layer of resin and at least one second layer of filled resin contiguous with the first layer, the second layer being flowable under a compressive force. In the manufacture of a reticulated laminated structure of substantially uniform thickness, the thickness of the second layer varies in accordance with the number of first layers overlying one another at crossover nodes in the reticulated structure, with the second layer flowing from between the plies of the first layer at the nodes due to compressive forces applied to achieve such substantially uniform thickness.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
92 words
A resinous material suitable for the fabrication of laminated structures comprising: a first layer of resin; and at least one second uncured and substantially non-self-curing layer of filled resin contiguous with said first layer, said first layer being relatively non-compressible compared to said second layer and said second layer being readily flowable under a compressive force and adapted to be easily squeezed out of the region of the force, said flowable second layer being adapted to retain said flowability for an extended period of time until used to fabricate said laminated structures.
