Method for testing interfacial shear strength of SiCf / SiC ceramic matrix composite fiber matrix

The invention belongs to the technical field of mechanical property testing of composite materials, and relates to a method for testing interfacial shear strength of a fiber matrix of a SiCf / SiC ceramic matrix composite material. The invention provides a test method for measuring the interfacial shear strength and the fracture energy of the fiber matrix of the SiCf / SiC composite laminate material based on an acoustic emission signal and a stress-strain curve in a continuous tensile loading process of a standard spline and fracture observation after a sample is broken. On the basis of the rule that accumulated energy is linearly proportional to crack density, indirectly calculating crack spacing under matrix crack saturation stress through normalized acoustic emission accumulated energy, so as to measure interface shear strength and matrix breaking strength. The method only needs to utilize a conventional standard sample strip tensile test to increase acoustic emission signal acquisition analysis and fracture analysis after the test, so that the test is greatly simplified, and the fiber matrix interface shear strength and matrix breaking strength of the block laminate material can be represented more truly.

The invention discloses an automatic driving automobile real-time integrity monitoring fault identification method using PPP-RTK, and relates to the field of automatic driving automobiles, and specifically, the method is mainly characterized in that fault satellites are filtered through a ground station network so as to identify hardware faults and position-related faults of a user side. The PPP-RTK is a promising positioning technology, and the positioning availability is not influenced while the calculation load in the IM task is reduced by utilizing the technology. The method is implemented by calculating the ratio between matched undifferentiated and uncombined (UDUC) residuals of a user receiver and the most recent reference station observations. The ratio is used to rank the respective observations, where the observation with the largest ratio is most likely to be erroneous. Thus, it is more possible to identify erroneous observations without generating and testing a large number of subsets. Furthermore, exclusion may be attempted for each observation, which preserves availability of the observation, unlike a grouping technique in which exclusion is performed on a satellite.
