Abstract
Abstract This invention is addressed to fiber-reinforced elastomeric products wherein the reinforcement fibers are in the form of a bundle of co-formed glass and synthetic organic fibers which are intimately admixed as they are formed and subsequently treated to form a thin size coating on the surfaces thereof and/or impregnated with an elastomer compatible material to improve the bonding relationship between the bundle of co-formed fibers and elastomeric materials.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A FIBER-REINFORCED ELASTOMERIC PRODUCT WHEREIN AN ELASTOMERIC MATERIAL CONSTITUTES A CONTINUOUS PHASE IN WHICH THE FIBERS ARE DISTRIBUTED, THE IMPROVEMENT WHEREIN THE FIBER REINFORCEMENT COMPRISES A BUNDLE OF A SUBSTANTIALLY UNIFORM BLEND OF ELONGATE CONTINUOUS GLASS FIBERS AND ORGANIC FIBERS FORMED FORM A FIBER-FORMING ORGANIC MATERIAL IN WHICH THE FIBERS HAVE BEEN BLENDED AS THEY ARE FORMED, EACH OF THE GLASS AND ORGANIC FIBERS HAVING A THIN FILM COATING ON THE SURFACES THEREOF FORMED FROM AN ANCHORING AGENT SELECTED FROM THE GROUP CONSISTING OF AN ORGANO SILICON COMPOUND AND A WERNER COMPLEX COMPOUND.

Claim 3
Dependent Claim
19 words
A fiber reinforced product as defined in claim 1 wherein the fibers are in the form of a strand.
Claim 4
Dependent Claim
26 words
A fiber reinforced product as defined in claim 1 wherein the fibers are in the form of two or more strands which have been plied together.
Claim 5
Dependent Claim
18 words

Claim 8
Dependent Claim
119 words
In a fiber-reinforced elastomeric product wherein an elastomeric material constitutes a continuous phase in which the fibers are distributed, the improvement wherein the fiber reinforcement comprises a bundle formed of a substantially uniform blend of elongate continuous glass fibers and organic fibers formed from an organic fiber-forming material in which the fibers have been blended as they are formed, with the individual glass and organic fibers forming the bundle each having a thin film coating on the surfaces thereof, said film coating containing an anchoring agent selected from the group consisting of an organo silicon compound and a Werner complex, and an impregnant in the bundle, said impregnant comprising an elastomer and substantially filling the interstices between the fibers.
Claim 9
Dependent Claim
119 words
