Document Type and Number:
Japanese Patent JP3126135
Kind Code:
B2
Abstract:
A nonwoven planar preform sheet for a polymer composite consisting of 20% to 80% by weight reinforcing fibers and 20% to 80% by weight matrix resin, said reinforcing fibers being from 1/8 to 6 inches in length and from 1 to 50 micrometers in diameter, and being arrayed in the composite as chips of from 2 to 5000 parallel filaments, each substantially uniformly coated with matrix resin, all of the filament of each chip ending in a single plane orthogonal to the filament direction, where the thickness of said subgrouping is from 1 to 50 filament diameters and the length to thickness ratio is greater than 100. The chips may be either randomly oriented or oriented in the same direction in the plane of the sheet.
