This article is a review of the properties of boron carbide (B₄C)-reinforced polymer composites. B₄C have recently become attractive to researchers, engineers, and scientists as an alternative reinforcement for polymer composites due to its attractive physical and mechanical characteristics. The tensile strength of the B₄C-reinforced epoxy was lower than the neat epoxy due to the poor bonding of the materials. Various surface treatments of the reinforcement were suggested in the literature to improve the bonding between the reinforcement and the matrix. B₄C addition improved the elastic modulus of the epoxy. No clear trend was observed for the flexural behavior of the same. It was mainly dependent on the type of epoxy used and size and concentration of reinforcement. A higher B₄C particulate addition in epoxy improved the hardness values of the composites. There was a marginal improvement in the shear strength of the B₄C-reinforced composites. The commonly observed plasticization tendency of epoxy after moisture absorption was less severe when epoxy was reinforced with B₄C particulates. Poor anchoring of B₄C particulates in the resin hampered the wear resistance of the composite. The situation further worsens after moisture absorption. However, cavitation erosion behavior of the composite improved and limited to localized areas.

本文综述了碳化硼 (B ₄ C) 增强聚合物复合材料的性能。B ₄ C 由于其有吸引力的物理和机械特性，最近作为聚合物复合材料的替代增强材料对研究人员、工程师和科学家具有吸引力。B ₄ C 增强环氧树脂的拉伸强度低于纯环氧树脂，这是由于材料的结合不良。文献中建议对增强材料进行各种表面处理，以改善增强材料与基体之间的结合。乙₄C的添加提高了环氧树脂的弹性模量。没有观察到其弯曲行为的明显趋势。这主要取决于所用环氧树脂的类型以及增强材料的尺寸和浓度。环氧树脂中较高的 B ₄ C 颗粒添加量提高了复合材料的硬度值。B ₄ C 增强复合材料的剪切强度略有提高。当环氧树脂用 B ₄ C 颗粒增强时，通常观察到的吸湿后环氧树脂的增塑趋势不太严重。B ₄锚固不良树脂中的 C 颗粒阻碍了复​​合材料的耐磨性。吸湿后情况进一步恶化。然而，复合材料的空蚀行为得到改善并仅限于局部区域。
