Abstract
Elastomer compositions and products formed therefrom, the compositions including one or more elastomers and glass microfibers having an average fiber diameter of no more than about 5 μm and an average length of between about 5 and 200 μm, wherein the glass microfibers are directionally oriented within the elastomer composition. Alternatively, the average length of the glass microfibers may be between 5 and 100 μm or in other embodiments, between about 10 and 70 μm.The elastomer compositions may be used to form products that include a tire tread or a support member within the sidewall of a tire. The glass microfibers may be oriented in, inter alia, a substantially circumferential orientation, a tread thickness orientation or at a 45° orientation in a plane formed between the tread thickness and circumferential orientations or in a sidewall thickness direction.
