GB/T 1448-2005 in English

《GB/T 1448-2005纤维增强塑料压缩性能试验方法》由TC39（全国纤维增强塑料标准化技术委员会）归口，主管部门为中国建筑材料联合会
本标准于1979年5月首次发布,1983年第一次修订，本次为第二次修订。本标准代替GB/T 1448-1983《玻璃纤维增强塑料压缩性能试验方法》。本标准规定了测定压缩性能的试样、试验设备、试验条件、试验步骤及结果计算等。本标准适用于测定纤维增强塑料的压缩应力和压缩弹性模量。

Fiber-reinforced plastics composites - Determination of compressive properties

1 Scope

This standard specifies the specimen, test device, test conditions, test procedures and result calculation for the determination of compressive properties.

This standard is applicable to the determination of compressive stress and compressive modulus of elasticity of fiber-reinforced plastics composites.
