Description

Technical Field

[0001] This utility model relates to the field of door and window profile technology, and in particular to a fiberglass reinforced polyurethane profile and glass doors and windows. Background Technology

[0002] So-called fiberglass reinforced polyurethane pultruded profiles are window and door profiles produced using polyurethane as the matrix and glass fiber as the reinforcing material through advanced injection impregnation pultrusion technology. Fiberglass reinforced polyurethane composite doors and windows have advantages in wind pressure resistance, air tightness, water tightness, sound insulation, fire resistance, and corrosion resistance. For example, Chinese patent CN220693070U discloses a fiberglass reinforced polyurethane solar photovoltaic frame profile. This profile uses fiberglass reinforced polyurethane material and has low cost, stable structure, and is not easily deformed during use. However, the vertical and horizontal beams of this profile are relatively long, resulting in high stress between the vertical and horizontal beams during use, making them prone to cracking and breakage. Therefore, to address these issues, a fiberglass reinforced polyurethane profile and glass doors and windows are proposed to solve these problems. Utility Model Content
