The method includes: providing structural yarns and functional yarns, wherein the functional yarns are electroluminescent fibers with electrode connecting sections at both ends; weaving the functional yarns and the structural yarns into a fabric, with the electrode connecting sections of the electroluminescent fibers extending from a predetermined position on the fabric; performing heat setting on the woven fabric, and then hot-pressing it using a mold to obtain the light-emitting automotive fabric headliner. By applying the technical solution of this invention, the intrinsic integration of the electroluminescent function and the fabric substrate can be achieved.

The utility model discloses a double -deck rubber band, solve the problem that current product double -deck structure is actually simple superposition, tenacity and strength are insufficient. The rubber band includes double -deck muscle and both sides reinforcing rib, the first layer muscle film and the second layer muscle film of double -deck muscle realize molecular chain crosslinking through arc strength film, and arc strength film adopts gradient vulcanization process and forms covalent bond connection, promotes interlayer peeling strength to 4.5N / mm, solves interlayer peeling problem. The reinforcing rib is composed of arc reinforcing sheet, first reinforcing strip, second reinforcing strip and reinforcing column, forms the three -dimensional support system similar to " I -steel ", and reinforcing column is evenly distributed in double -deck muscle both sides, and the stress is dispersed when drawing, and local strain is reduced. This design makes the rubber band breaking elongation reach 800%-1000%, and the fatigue life is improved by more than 5 times, is applicable to industrial packaging, sports training and other high -frequency tensile scene, and the mechanical property is enhanced significantly.

This invention belongs to the field of metal-ceramic composite materials technology, specifically relating to a high-performance metal-ceramic composite grinding roller and its preparation method. The grinding roller consists of a grinding surface layer, a pure metal transition layer, and a tough roller core, which are metallurgically integrated. The grinding surface layer is a composite of a multi-system ceramic reinforcing phase and a high-toughness, high-chromium cast iron matrix. The ceramic particles are treated with a NiP amorphous coating and optimized through a three-level particle size distribution and PSZ secondary reinforcing phase optimization. The roller core is made of medium-carbon alloy steel. The preparation method includes five steps: ceramic preform preparation, roller core pretreatment and assembly, centrifugal casting composite, vacuum sintering densification, and differential temperature heat treatment and finishing. This invention fundamentally solves the technical bottlenecks of weak bonding between ceramic and metal interfaces and uneven particle distribution through multiple technological couplings. The prepared grinding roller possesses both ultra-high wear resistance and excellent impact resistance (impact toughness AKU>30 J in the transition zone), with a uniform, dense, and defect-free microstructure, and a service life more than three times that of traditional high-chromium cast iron grinding rollers.
