Title: Quality measuring method for resin based composite material
Inventor: MATSUMOTO TAKESHI
IPC: C08J5/24
Filed: 1992-12-25
Abstract: PURPOSE:To allow simple and highly accurate measurement by heating a test piece of a resin-based composite material, causing reaction on the test piece at a predetermined temperature, and then measuring the time to be elapsed before the end of the reaction after the start of heating. CONSTITUTION:A test piece 5 of a resin-based composite material is contained in a container 6 placed in a heater unit 7 in order to heat the test piece 5. When the temperature in the unit 7 reaches a predetermined level, that temperature is sustained. When the test piece 5 is heated and the temperature in the unit 7 is sustained at a constant level, exothermic reaction takes place in the test piece 5 to cause reduction of the heat quantity to be held thus displacing the test piece 5. When a predetermined time (t) elapses, the reaction ends to bring about an equilibrium state. The time (t) to be elapsed before the equilibrium state is brought about is measured. The time (t) is compared with a reference time previously measured for a correctly mixed resin-based composite material and the quality of the resin based composite material is decided depending on the fact that the time (t) comes within a correct range or not.
