Cellulose acetate fiber having non-circular cross section,

A fiber-reinforced polymeric resin composite material useful for producing a shaped composite article having a high thermal stability and mechanical strength, and a low creep strain, comprises a thermoplastic polymeric resin matrix and a number of reinforcing individual fibers embedded within the polymeric resin matrix in such a manner that 10% to 70% by the number of the individual fibers are separated from each other through portions of the polymeric resin matrix and the remaining individual fibers form at least one fiber bundle.

Fiber-reinforced polymeric resin composite material and process for

A yarn package which is provided with a saw-shaped traverse stroke profile, similar in some respects to that of a pine cone, and to a method for winding the same. This shape, by providing a periodic variation in the effective winding height, minimizes irregularities in the yarn due to compression and relaxation stresses.
