FIBROUS PULP AND USE THEREOF IN A COMPOSITE |
| 摘要 |
A composition comprises (i) an elastomer, (ii) from 1 to 5 volume % of fibrous pulp, the pulp having a specific surface area of from 7 to 11 sq.m./g and the fiber having a fiber length of from 0.5 to 1.1 mm, a tensile modulus of from 2.5 to 130 GPa, and a tensile strength of from 1 to 3 GPa, and (iii) from 5 to 14 volume % of yield-strain promoter in the form of fibers, needles, powder or platelets, wherein the composition has a yield strain of at least 70%, an elongation at break of at least 200%, and a yield stress of at least 4 MPa. |
