Abstract
Abstract A high modulus structural ply for a pneumatic tire which is composed of mutually parallel, continuous cords embedded in an elastomeric compound which contains uniformly dispersed, short fibers oriented in a particular direction. Such a ply construction may be utilized as carcass plies and/or breakers in ''''bias-ply'''' tires or, as carcass plies and/or belts in ''''radialply'''' tires.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
61 words
In a pneumatic tire which includes a cord-ply member comprising spaced, mutually parallel, continuous lengths of cords in an elastomeric matrix containing fiber reinforcement, the improvement wherein said reinforcement consists of a plurality of short, discrete filaments, said filaments being a. uniformly dispersed throughout said elastomeric matrix, and b. oriented in a predetermined direction relative to said continuous lengths of cords.
Claim 2
Dependent Claim
61 words
In a pneumatic tire which includes a cord-ply member comprising spaced, mutually parallel, continuous lengths of cords in an elastomeric matrix containing fiber reinforcement, the improvement wherein said reinforcement consists of a plurality of short, discrete filaments, said filaments being a. uniformly dispersed throughout said elastomeric matrix, and b. oriented in a predetermined direction relative to said continuous lengths of cords.
Claim 3
Dependent Claim
15 words
The structure as defined in claim 1, wherein said pneumatic tire is a bias-ply tire.
Claim 4
Dependent Claim
14 words
The structure as defined in claim 2, wherein said cord-ply member is a carcass-ply.
Claim 5
Dependent Claim
14 words
The structure as defined in claim 2, wherein said cord-ply member is a breaker.
Claim 6
Dependent Claim
15 words
The structure as defined in claim 1, wherein said pneumatic tire is a radial-ply tire.
Claim 7
Dependent Claim
14 words

Claim 9
Dependent Claim
62 words
In a pneumatic tire which includes a cord-ply member comprising spaced, mutually parallel, continuous lengths of cords in an elastomeric matrix containing fiber reinforcement, the improvement wherein said reinforcement consists essentially of a plurality of short, discrete filaments, said filaments being a. uniformly dispersed throughout said elastomeric matrix and b. oriented in a direction substantially parallel to said continuous lengths of cords.
Claim 10
Dependent Claim
62 words
In a pneumatic tire which includes a cord-ply member comprising spaced, mutually parallel, continuous lengths of cords in an elastomeric matrix containing fiber reinforcement, the improvement wherein said reinforcement consists essentially of a plurality of short, discrete filaments, said filaments being a. uniformly dispersed throughout said elastomeric matrix and b. oriented in a direction substantially parallel to said continuous lengths of cords.
Claim 11
Dependent Claim
14 words
The structure as defined in claim 8, wherein said cord-ply member is a carcass-ply.
Claim 12
Dependent Claim
14 words
