Abstract

The invention belongs to the technical field of information materials, in particular to a preparation method of a polyetheretherketone flexible sensing array. The method proposed by the present invention is to combine (3aR, 8aS, 8bS)-1,3-dibenzyl-2-oxodecahydroimidazo[4,5- c ]thieno[1,2‑ a ] Sulfonium chloride, (3S,7aR)-3-phenyl-6-benzyl-7-hydroxy-imidazo[1,5- c ] Thiazole-5(1H,3H,6H)-ketone, polyvinyl alcohol, polyvinylidene fluoride, polychlorotrifluoroethylene, carbon nanotube, and graphene are added to tetrahydrofuran, and heated in an autoclave to obtain a sensing ink; Then, on the surface of the polyether ether ketone fabric, the pattern of the sensing ink array is screen-printed, and then dried in a hot embossing machine to obtain a flexible sensing array of polyether ether ketone. The polyetheretherketone flexible sensing array is used as a liner and sandwiched between the inner and outer rings of the aviation spherical plain bearing. The sensing sensitivity of the flexible sensing array to stress strain, temperature and humidity is tested on the aviation bearing testing machine, and the sensitivity is 8.1~9.8 respectively. , ‑1.83×10 ‑3 ~‑1.11×10 ‑3 K ‑1 And 991%~1104%.

Description

technical field [0001] The invention belongs to the technical field of information materials, and specifically relates to a preparation method of a polyether ether ketone flexible sensing array. Background technique [0002] The joint bearing is a self-aligning sliding bearing, which slides on the contact surface of the inner and outer rings, so the friction and wear are relatively large. The joint bearing can rotate around the axis of its inner hole, and can also perform non-centering motion around two stationary axes. Because the joint spherical bearing has a large swing angle and self-aligning performance, it can realize rotation, swing and self-alignment. While bearing a large radial static load, it can also bear a certain axial load, which helps to improve the flexibility of aircraft components, and is widely used in aerospace machinery. [0003] Bearing failure is one of the most common failure and damage causes of machines. There are many reasons for bearing failure....
