Abstract
This invention is directed to a fiber reinforced adhesive composition comprising a pressure sensitive adhesive matrix and a fibrous reinforcing material within the pressure sensitive adhesive matrix. The adhesive composition has a yield strength and a tensile strength. The tensile strength is at least about 150% of the yield strength. Generally, the adhesive composition exhibits these properties at least 50% elongation when measured according to ASTM D 882-97 at a crosshead speed of 12 inches/minute (30 centimeters/minute).
Claims31
