Abstract: A product and process of manufacturing a non-woven web from cotton regin for use as an industrial hydrophobic absorbent, a filter or insulator. The method of processing the cotton regin creates a low-density and, thus, a high-absorbency web. The finished web has a bulk-to-weight ratio of about 25 to 40 mils/osy. The method includes processing cotton regin to a suitable range of fiber and particle sizes, mixing the cotton regin with a thermoplastic bonding agent, and depositing the material onto a steadily advancing belt to produce a relatively low density, loosely formed web. Subsequent processing of the web in an oven softens or melts the bonding agent, thereby adheres it to other web material to give the web its required strength and integrity. One or more continuous, air-permeable layers of scrim or netting may be incorporated on or within the web to provide additional strength or particular surface characteristics.

Abstract: Both ceramic and intermetallic materials as a rule have a very small elongation at break of distinctly less than 0.3% and therefore a break behaviour with low damage tolerance. In order to increase the damage tolerance, it is important to increase the elongation at break to at least 0.3% or more. This can be achieved by introducing, for example, fibres consisting of carbon or ceramic or metal fibres into the matrix. It is important in this respect for the distribution of the fibres in the matrix to be homogeneous and/or defined. It is of advantage and therefore as a rule desirable for the fibres for reinforcing a material or component to be oriented in a defined direction which is adapted to the main stress.
