Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
60 words
A cold wall having a number of guide ribs thereon, wherein the cold wall and the guide ribs are a composite material comprising a matrix and conductive fibers, wherein the fibers are woven in a cross-ply manner with an unbalanced fiber ratio oriented in a direction to facilitate heat transfer through the guide rib and further through the cold wall.
Claim 2
Dependent Claim
60 words
A cold wall having a number of guide ribs thereon, wherein the cold wall and the guide ribs are a composite material comprising a matrix and conductive fibers, wherein the fibers are woven in a cross-ply manner with an unbalanced fiber ratio oriented in a direction to facilitate heat transfer through the guide rib and further through the cold wall.
Claim 3
Dependent Claim
29 words
The cold wall of claim 1 wherein the matrix is selected from the group consisting of a resin matrix, a metal matrix, a ceramic matrix, and a carbon matrix.
Claim 4
Dependent Claim
16 words
