Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a heat-resistant whisker composite material and a preparation method thereof. Background technique [0002] Research on composite materials is a very active scientific research field in recent years, and is expected to have a profound impact on society in the future. Among the numerous research directions of composite materials, it is always of great significance to introduce inorganic fillers into polymers to obtain significant performance improvements. These composite materials have greatly enhanced the polymer matrix in terms of mechanical properties, electrical properties and thermal properties, and can be widely used in marine, automotive, aerospace and other fields that require high mechanical properties and heat resistance. The more important point about this type of composite material is that the reinforcement only needs a small amount of addition to improve ...
