FIELD: construction engineering; plastic window and door cases and frames. SUBSTANCE: building member has intricate developed surface of composite material based on intersecting glass fibers and longitudinally oriented rovings joined by polymeric binder obtain by thermal broaching through spinneret assembly. Linear bar is made of glass fiber mats of surface density 100-400 g/m2 with chaotically intersecting glass fibers uniformly distributed on longitudinally oriented rovings at open end of external surfaces of bar developed profile. Volume ratio of glass fiber mats and rovings to binder in composite material is from 1:0.5 to 1:0.75. EFFECT: improved stiffness, strength, and operating reliability of member. 2 cl, 14 dwg
