REINFORCING BEAMS OF FIBERS FOR THE PRODUCTION OF REINFORCED POLYMERIC COMPOSITES

摘要

1. A composition containing fibers suitable for compounding with a matrix polymer in a compounding method for forming a fiber-reinforced polymer composite, said composition comprising a mass of bundles of cut fibers, said mass having an average bulk density of at least 0.256 g / cm3 (16 pounds per cubic foot), and in which essentially all of these bundles of cut fibers have a length of between about 3 and 15 mm, and include many synthetic fibers or natural fibers based on cellulose, essentially the same length, oriented essentially parallel to each other and having ends of substantially the same length with each other, and in which essentially all bundles of cut fibers further include a coating composition that covers the fibers within the bundles and forms fragile interfiber bonds within each bundle of cut fibers to provide interfiber adhesion, and these fragile interfiber bonds are able to break when compounding these bundles in the process of comp ndirovaniya such that said cut fiber bundles can disintegrate into separate individual fibers for dispersion within the matrix polymer during said process. ! 2. The composition according to claim 1, in which the specified mass of the bundles of cut fibers has a fluidity to such an extent that the specified mass of bundles can be fed evenly for compounding with a volume or weight screw batcher. ! 3. The composition according to claim 2, in which the mass of the bundles of cut fibers has a fluidity to such an extent that the mass can be p
