Abstract Burning method is widely used in determining the resin content of glass fiber composite materials. The burning method can not be used to determine the resin content in the glass fiber composite of organosilicon resin, as the resin base can not be completely removed by burning.Density method is to calculate the resin content by measuring the density of glass fiber, sample and resin. Two different method are used to test the resin content of same batch of glass fiber composite materials. According to the results, the resin content of the density method is 40.8% and the burning method is 38.6%. The expanded uncertainty of the density method is 1.2% and the burning method is 0.3%. The accuracy of density method is slightly lower than that of burning method, but it can be used to determine the resin content of silicone resin glass fiber composites and meet the index requirements. Therefore, the density method can replace the burning method to test the samples, but the experimental process needs to be strictly controlled to improve the accuracy of the test results.

Key words： metrology density method organosilicon glass fiber composite resin content uncertainty
