Electromagnetic interference shielding |
摘要 |
A foamed aqueous dispersion of a mixture of particulate plastics material is formed when the fibers are between 5% and 35% of the volume of the mixture, where no more than about 7% of the volume of the mixture is conductive fibers between about 7 and 20 mm long, and where any other fibers are reinforcing fibers with a high modulus of elasticity and between about 7 and about 50 mm long. A web is formed from the foamed dispersion using a wet laying process. The web is dried and compacted under heat and pressure. The compacted web is cooled to form a consolidated element in which the conductive fibers extend as a conductive lattice. The resulting element can be formed or molded into shielding to provide attenuation of electrical or magnetic fields.
