ABSTRACT:
The invention pertains to a method for forming a construction member of glass fiber elements impregnated with a hardened resin. The method includes the interposing of elongated, high density, glass fiber rods consisting of a plurality of longitudinally disposed glass fibers bonded together with a hardened binder resin while under tension between layers of glass fiber fabric impregnated with a hardenable resin. The resin of the fabric impregnates the interstices between the rods forming a high strength integral, homogeneous, bonded member. The method of the invention is used to form plank type members of linear or curved configuration wherein a mold is usually utilized.
