Abstract: Radome for civil aircraft shall be designed to meet requirements in CCAR25. 613 "Material Strength Properties and Design Values". Through the study to the past experiences,this paper designs the test items,teststandards,test environments,as well as test specimen contents and test data treatment methods for material allowables of civil aircraft radomes. Comparison between the data obtained through the adopted ASTM methods in this paper and the results from the conventional GB standards show that the material allowable data in this paper has low coefficients of variation and higher value for allowable data. The methods thus avoided the low property value by the GB standards for glass fiber reinforces composite material. The test result has been proved successful by radome design and radome static tests of ARJ21 civil aircraft.

Key words: radome, glass fiber reinforce composite, design allowable
