Abstract: The invention is related to a composite material testing equipment designed for the automatic, super-speed, and large-scale yarn-strength testing in a manner affording the possibility of displaying and recording the results of the said tests continuously and -- practically -- at the same time as the test takes place.N pieces of breaking units each of them comprising at least one sensor are mounted upon a common supporting block, and coupled to a single, common drive. The program-controlled drive and the sensors are connected to the control unit of a data processing and control network. The network comprises a RAM-memory connected to several channels of the control unit whereas its data outputs are parallelly connected to the inputs of two registers, the outputs of the registers being coupled to an adder stage, and the output of the latter is connected to a D/A converter.
