Embodiment 1

[0027] This embodiment provides a hatch door heat-sealing material component and its preparation method, according to image 3 Shown method flow process is prepared, specifically comprises the following steps:

[0028] 200tex fiberglass with The stainless steel fiber wire is blended and woven according to the ratio of the number of strands at 5:1. heat-sealed rope. Cut two sections of the same length of the heat-sealed rope, use 1 strand of the same metal fiber wire to carry out 8-shaped side-by-side suture connection, and the suture stitch distance is 10mm to make a 8-shaped heat-sealed rope. Using this as a weaving template, weaving it into a ceramic fiber sheath online to make a heat-sealed material, such as figure 1 shown.

[0029] Use metal materials to process L-shaped metal fixing parts, and the installation hole diameter of the metal fixing parts is The hole distance is 30mm. The shape of the metal fixing piece is L-type or C-type or S-type, such as figure 2...

Abstract

The invention relates to a cabin door heat sealing material component and a preparation method thereof. The method comprises the steps of blending and weaving ceramic fibers and metal fibers into a heat sealing rope; cutting two sections of equal-length heat sealing ropes, and sewing and connecting the two sections of equal-length heat sealing ropes side by side in an 8 shape by using metal fibers to prepare an 8-shaped heat sealing rope; taking the 8-shaped heat sealing rope as a weaving template, using fiber cloth for wrapping and sewing, forming a ceramic fiber maintenance sleeve, and preparing a heat sealing material; machining a metal fixing piece, heating a small mounting hole of the sealing material through a machine, and machining a mounting hole in the fixed contact surface of the metal fixing piece and the cabin door; binding and fixing the heat sealing material and the metal fixing piece through metal fibers; and sealing a gap between the contact surface of the heat sealing material and the metal fixing piece to prepare the cabin door heat sealing material component. The cabin door heat sealing material component can be directly used as an assembly to be installed on a cabin door or a cabin door frame, is a high-reliability heat-sealing material component of various cabin doors of aircrafts, and has high-temperature heat-sealing application value of cabin doors of aviation and aerospace aircrafts.

Description

technical field [0001] The invention relates to a hatch door heat-sealing material component and a preparation method thereof, belonging to the technical field of hatch door sealing. Background technique [0002] Due to the slow flight speed of conventional aircraft, the external temperature environment of the hatch door is relatively mild. The matching structure of the hatch door and the door frame, or conventional organic rubber materials can be used as sealing materials to seal the hatch door. As the speed of aviation and aerospace vehicles becomes faster and faster, the external thermal environment of the aircraft door becomes harsh. Conventional rubber materials cannot withstand such high temperature use, and the special matching structure design of the door and door frame cannot completely solve the problem of the door / frame The heat insulation and sealing problem of the gap, the heat sealing function of the cabin door fails, causing the internal temperature of the fun...
