USE OF A FIBRE-REINFORCED PLASTIC MATERIAL AS A REINFORCEMENT SYSTEM OF A PROFILE FOR A WINDOW OR DOOR FRAME

摘要

The invention relates to the use of a fibre-reinforced plastic material comprising an E-module that is > 8.000 N/mm2, preferably > 10.000 N/mm2, having a softening temperature of > 100°C, preferably > 150°C and an elongation coefficient of -5K-1, preferably -5K-1 most preferably -5K-1, in particular to the use of fibre-reinforced polybutylenterephtalate, polyetylenterephtalate or a mixture thereof, as reinforcement strips (2, 6, 7, 14, 15) of a window or door frame hollow profile (1, 10).
