Abstract
Disclosed is a method for laying slit of C/C composite material brake disk, belonging to the technical field of composite material forming. Firstly, preparing the single direction C/C composite material and analyzing the wear resistance performance to obtain the optimal slit laying direction for laying fiber under working environment, thereby making the fiber slit laying track and compiling slit laying motion control codes; the analyzing the prefabricated slit laying brake disk, cutting carbon fiber cloth sheets into fan-shaped sheets according to the radial arc on the designed brake disk, arranging these carbon fiber cloth sheets in ring shape on an automatic slit laying equipment, then machining the laying slit; and performing stand test and performance analysis for the test piece to perform optimized improvement. The method reduces the manufacturing cost, and promotes the market competition of the brake disk and related technical products.
Description
Technical field
Technical field of composite material molding.
Technical background
States such as external English, U.S., method almost are used for the C/C composite material aeroplane brake discs simultaneously at late 1960s, the beginning of the seventies, progressively substituted metal and common friction material become state-of-the-art brake material at present.Mainly contain five big manufacturer production C/C composite material brake discs in the world today, they are respectively American AB S (Aircraft Braking System) company, ALS (Aircraft Landing Systems) company, B.F.Goodrich company, French Mes sier-Bugatti company, Britain Dunlop company, and three states, five major companies have monopolized the international market of C/C composite material brake disc; C/C composite preform technology and carbonization also are the proprietary technology of each company oneself, and core technology rarely has open report.Domesticly develop the C/C composite material brake disc since the end of the seventies in last century, enter the nineties, China adopts the brake disc of pin felt method development to come into operation, and the performance performance is good; But the brake disc expense that adopts pin felt manufactured is compared external brake disc cost competitiveness deficiency than higher.
Summary of the invention
C/C composite material brake disc seam spreading method of the present invention is intended to seek a kind of new brake disc precast body manufacture method and reduces manufacture cost, promotes the market competitiveness of brake disc and relative technological products.
By Fig. 1 the present invention program is described, at first carries out the preparation of unidirectional C/C composite material, these goods are carried out off-axis friction-wear test and finite element analysis; Draw its shop seam direction, performance and the shop seam mechanism of environment lower berth seam fiber under arms, thereby formulate the fiber Topology Optimization Method.
Then shop seam brake disc precast body is analyzed,, the carbon fibre cloth sheet is cut into fanning strip, make all fanning strips can be combined into a ring that meets the brake disc profile according to actinoid arc on the design brake disc; These carbon fibre cloth sheets are arranged in ring on the seam equipment of shop automatically, are adjusting shop seam initial position, spreading seam processing then.
Test specimen is carried out stand test and performance evaluation, fan plate shape optimization on the brake disc is improved, analyze the brake disc design method under the different operating modes, and provide the shop tailor codes and standards of planting.Fan the stitching track of chip architecture and shop seam fiber according to brake disc and work out automatic shop seam control software, the automatic shop of importing seam equipment is spread seam processing then.
The present invention is as the next-generation technology of pin felt manufactured brake disc technology, simple to operate, easy control can produce high-performance C/C composite material brake disc, and added value can improve more than 10%, the easier international high-end C/C composite material brake disc market of squeezing into has extraordinary industrialization prospect.
