Design and Experimental Study of a Composite Materials Micro-Deformation Measurement Device

Abstract:

In the space environments, the size and weight of composite materials will produce small changes. In order to measure the small changes accurately, a micro-deformation measurement device has been designed. The carbon fiber tube was made from cyanate ester resin or epoxy resin was tested in vacuum and hygrothermal environments. The deformation in the vacuum test is -1.7 to 3.8 microns, in the hygrothermal test, the deformation is -1.3 to -6.4 microns. The same as theoretical analysis, the environmental stability of cyanate ester resin better than epoxy resin.
