Fiber-composite material and method of preparing the same

A method for the composite material (7), wherein the composition is as follows: Yarn material (6), comprising at least 1 bunch of the carbon fibre (3) and fibre yarn of the component (a) and 2B) is three-dimensional compound and an extrusion and each other without generating; As a matrix of the Si-SiC base material is prepared (sieve, 4B, 5A and 5B), which includes a yarn material (6) are by the yarn (and a 2B) is. The preparation method for the composite material, comprising the following steps: A at the carbon powder component to the carbon fibre (3) preparing the carbon fibre is 4.5-15 (3), wherein ultimately on the substrate, andJoint (3) is formed plastic paint according the carbon fibre, thereby obtaining the intermediate material; The of the intermediate material according to yarn is a predetermined amount, thereby forming material by moulding the moulded article, or to obtain the oil product of the moulded article of base oil; In an inert gas atmosphere the moulded article or oil product and at Si, 1100~1400℃The heated by moulding product or oil product and 1450~2500℃ Si, wherein the Si-SiC base material is a moulded article or the oil product and. Providing a light and solid composite material, comprising a inoxidizability of high anti-shocking, and corrosion environment comprises the step of oxidizing, the anti-creep and anti-spallation, resistance by using and friction coefficient and from the capacity of the obtained heals.
