    Abstract: Disclosed is a soil reinforcing resin net including hole portions (5) arranged in the longitudinal and transverse directions of said resin net, each of which is formed by a pair of opposed ribs (5a) and a pair of opposed bars (5b), wherein projecting portions (6) are fixed on bar portions; a method of producing the soil reinforcing resin net; and a drawn product of a polyethylene based resin suitably used as the soil reinforcing resin net, which is obtained by drawing a polyethylene based resin composed of a linear ethylene main chain having 0.3 or more of saturated hydrocarbon groups branched thereto in one molecule.

    Abstract: A fiber composite material in which short fibers, such as polyester short fibers, are added to a matrix, such as a cross-linked rubber matrix, is provided, wherein a heat shrinkage ratio of the short fibers is 8% or less at fiber composite material molding temperatures of 140 to 200 DEG C. Also provided is a pneumatic tire in whose tire tread the fiber composite material is used. Such pneumatic tires include pneumatic tires provided with a foamed rubber layer in a fire tread. The foamed rubber layer has an average cell diameter of 10 to 120 mu m and an expansion ratio of 3 to 50%. A solid phase rubber portion of the foamed rubber layer includes 5 to 55 parts by weight of carbon black, 55 to 5 parts by weight of silica, and 1 to 15 parts by weight of short fibers to 100 parts by weight of a diene-base rubber component including 70 to 20 parts by weight of natural rubber and 30 to 80 parts by weight of polybutadiene rubber. A surface of the tire tread has a hardness of 52 or less at 0 DEG C. The short fibers have a length which is from 0.5 to 3 mm and which is shorter than a minimum gap between sipes of a tire surface, a diameter of 30 to 100 mu m, an aspect ratio of 5 to 100, and a heat shrinkage ratio of 8% or less at 140 to 200 DEG C. On-ice performance of the pneumatic tire of the present invention is excellent.
