Problems solved by technology

[0003] The structure of the core material in the traditional broken bridge aluminum alloy door and window system is complicated, the precision is not high, and the installation is inconvenient. In addition, in the wide core material structure, the strength of the core material is insufficient, resulting in low dimensional accuracy of the door and window, insufficient structural rigidity, and unreliable performance.
The traditional broken bridge aluminum alloy cannot meet the fire protection requirements of the fire protection design code
Insulation is not fireproof, fireproofing is not energy-saving, how to perfectly unify the two is a difficult problem

Abstract

The invention discloses a core material, a composite sectional material, a door and window frame and manufacturing methods thereof. The two side portions of the core material are each provided with atleast one face, the mutual parallelism between the two faces is not larger than 0.3 MM, the side portion of the core material is provided with at least one cantilever, the parallelism between at least one face of the cantilever and at least one face of the other side portion is not larger than 0.3 MM, and the core material is made of a continuous fiber reinforced composite material, and the fibercontent is not lower than 40% by weight.

Description

technical field [0001] The invention belongs to the field of broken bridge aluminum alloy door and window systems, and in particular relates to a core material, a composite section material, a door and window frame and a manufacturing method thereof. Background technique [0002] With the improvement of living standards, people's requirements for room lighting are getting higher and higher. The windows of ordinary houses and high-rise buildings are getting bigger and bigger, and the ratio of windows to room area is constantly increasing. Window frame is a commonly used component of various buildings. The traditional aluminum alloy window frame profile has excellent heat transfer performance, and it has become the main channel for transferring heat indoors and outdoors. It is greatly affected by the outdoor temperature, so the broken bridge window came into being. The broken bridge window uses heat-insulating broken bridge profiles to make the frame, and penetrates the heat-...
