Abstract

The invention provides a carbon fiber felt reinforcement inorganic polymer matrix composite and a preparation method of the carbon fiber felt reinforcement inorganic polymer matrix composite, and relates to an inorganic polymer matrix composite and a preparation method of the inorganic polymer matrix composite, in particular to the carbon fiber felt reinforcement inorganic polymer matrix composite and a preparation method of the carbon fiber felt reinforcement inorganic polymer matrix composite. The problems that an existing inorganic polymer material is poor in mechanical performance and low in toughness and the operation for adding short carbon fiber is complex are solved. The product is prepared through inorganic polymer material pulp and carbon fiber felt. The inorganic polymer material pulp is prepared through potassium hydroxide, silica sol and aluminosilicate powder. The method includes the steps of firstly, preparing the inorganic polymer material pulp; secondly, washing the carbon fiber felt; thirdly, preparing a prefabricated material blank; fourthly, preparing the carbon fiber felt reinforcement inorganic polymer matrix composite. The method is simple in process, low in cost, environmentally friendly and capable of being use for large-area preparation, and the prepared composite is good in mechanical property and wider in application range.

Description

technical field [0001] The invention relates to an inorganic polymer-based composite material and a preparation method thereof, in particular to a carbon fiber felt-reinforced inorganic polymer-based composite material and a preparation method thereof. Background technique [0002] Inorganic polymer materials have the characteristics of high temperature resistance, heat resistance, low density, low cost and good flame retardancy, and have low preparation temperature, simple process, and low energy consumption. They have been used in construction, refractory materials and aviation fields . However, factors such as inherent brittleness, poor toughness, and low mechanical strength of inorganic polymer materials severely limit their application range. [0003] Carbon fiber reinforced ceramic matrix composites overcome the shortcomings of high brittleness of ceramic materials, while maintaining the advantages of ceramics and have been widely used. The addition form and distribu...
