热结构复合材料是由轻质和耐火成分（如碳和碳化硅）制成的，这些成分相关联以获得其中耐火基质由高性能纤维增强的复合材料。本章阐述了这些复合材料如何证明它们作为高性能摩擦应用系统的成分的重要性。两种主要类别的陶瓷基质复合材料（CMC）材料用于摩擦应用：（i）碳/碳复合材料，主要用于飞机制动系统和赛车汽车;和（ii）碳/陶瓷复合材料，更适合于陆地应用（例如，乘客汽车、电梯）。对于碳/碳和碳/陶瓷这两种材料，制造量不断增长，但与传统的金属/有机材料相比，材料成本仍然非常高。未来的发展包括制造和最终加工的更快、自动化流程，以及更简单的几何形状和新型设计的金属类垫片和圆盘。
Thermostructural composite materials are manufactured from light and refractory components like carbon and silicon carbide, associated to get composites in which a refractory matrix is reinforced by high performance fibers. This chapter illustrates how these composites have proven their interest as constituents in systems for high performance friction‐based applications. Two main classes of ceramic matrix composite (CMC) materials are used for friction applications: (i) carbon/carbon composites, mainly used for aircraft braking systems and racing cars; and (ii) carbon/ceramic composites, more suitable for terrestrial applications (e.g., passenger cars, elevators). For both materials, carbon/carbon and carbon/ceramic, the manufactured quantities are constantly growing but still burdened with very high material costs compared to conventional metal/organic materials. Future developments comprise faster, automated processes for the manufacture and final machining as well as simpler geometries and novel designs of the still metal‐like pads and disks.
