Abstract

Abstract

In order to improve the densification efficiency and load-bearing performance of needle punched carbon/carbon (C/C) composites, needle punched preforms B-NPs with 16 mm spreading coth and felt tire alternating layers, needle punched preforms H-NPs with 8 mm spreading coth and felt tire alternating layers, and needle punched preforms T-NPs with B-NPs structure on the outer layer and H-NPs structure on the inner layer were designed. Three types of needle punched C/C composites were prepared by combining chemical vapor infiltration and impregnation-carbonization processes. The densification efficiency, porosity and pore distribution of three kinds of needle punched C/C composites were statistically analyzed by Archimedes drainage method and X-ray computed tomography (Micro-CT) technology, and three-point bending mechanical properties were tested at room temperature. The results indicate that as the width of the widened yarn increases, the densification efficiency of the needle punched C/C composite material is improved, and the internal porosity decreases. Within the same densification time, B-NPs have the best densification effect, with a density of 1.42g/cm³ and a porosity of only 10.67%. Under three-point bending load, the three materials all show brittle failure. The bending strength and flexural modulus of T-NPs are 173.04 MPa and 25.03 GPa respectively, which have excellent bending resistance. The initial failure of the three materials all occurs near the needle punched fiber bundle, with fiber fracture being the main failure mode for the low porosity B-NPs needle punched fiber bundle and carbon cloth layer; High porosity H-NPs fiber/matrix interface has poor bonding ability, and the failure of carbon cloth layer is dominated by fiber/matrix debonding and fiber pullout.
