Parabolic component gradient variation of gf improves 18 % of gf homogeneous distribution on bending strength ; linear component gradient variation only does 6 % 抛物线梯度分布组28天抗弯强度比均匀试件提高达18 ,而线性梯度提高6 。

Linear component gradient variation of aggregates improves 16 % of aggregates homogeneous distribution on bending strength ; parabolic component gradient variation does 8 % . gf is widely used as composite reinforcement due to low cast and excellent properties such as high tensile strength and high elastic modulus 抛物线梯度不如线性梯度增强效果好,线性梯度变化比均匀分布试件抗折强度提高了16 ,抛物线梯度提高了8 ;玻璃纤维的高抗拉强度及较高的弹性模量,提高了纤维混凝土复合材料的拉伸强度和弹性模量。
