Abstract
Abstract A knitted fabric panel structure has first and second spaced apart knitted layers and an intermediate spacing knit of ribs interconnecting the layers, the ribs of the spacing unit being of an industrial yarn of aramide fiber, carbon fiber, ceramic fiber, fiberglass, or blends of such fibers. The spacing knit is impregnated with a hardened resin such that the intermediate ribs form rigid spacing elements of the first and second layers.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
98 words
A knitted fabric panel structure, comprising first and second spaced apart knitted layers, and an intermediate spacing knit of ribs interconnecting said layers, the ribs of said spacing knit comprising an industrial yarn selected from the group consisting of aramide fiber, carbon fiber, ceramic fiber, and fiberglass, said spacing knit being impregnated with a hardened resin such that the intermediate ribs form rigid spacing elements of the first and second layers, wherein said intermediate ribs are curved in one direction between opposite ends thereof and are angularly disposed in another direction relative to said first and second layers.
