Fiber composite material and method for producing same by virtue of RTM forming method
A fiber composite material and a molding method technology, which are applied in the field of fiber composite materials and the production of the composite material by using the RTM molding method, can solve the problem that the batch setting processing requirements cannot meet the production process requirements of hot-melt prepregs, and the viscosity is low and cannot be formed into a film. and other problems, to achieve the effect of large-scale stereotype processing, meeting the requirements of the injection process, and good viscosity

Example Embodiment
[0047] Example 1
[0048] The preparation raw materials used include: 30% bisphenol A type cyanate resin, 30% novolac epoxy resin and 40% bisphenol A epoxy resin. It should be noted that the percentage content here refers to the percentage of the component mass in the total mass of the raw materials. The percentages mentioned below (including Table 1) all have this meaning.
[0049] Dry fabric selection: G0827 unidirectional carbon fiber fabric with an areal density of 165g / m 2 , Fiber type T300-3k.
[0050] The bisphenol A type cyanate ester resin and epoxy resin are fully stirred evenly at room temperature using a double planetary mixer. Grind the mechanically-stirred resin system through a three-roll mill, control the resin temperature not to exceed 60°C, minimize the melting of the cyanate ester powder, and make the bisphenol A cyanate ester resin uniformly dispersed in the epoxy as a solid powder In the resin. The bisphenol A cyanate ester modified RTM epoxy resin system was...
Example Embodiment
[0053] Example 9
[0054] The preparation raw materials used are the same as in Example 1, and the production method is different from that in Example 1: The first temperature is 90°C.
Example Embodiment
[0055] Example 10
[0056] The preparation raw materials used are different from those of Example 1, and there are the following differences: 43% novolac epoxy resin + 57% bisphenol A epoxy resin, which does not contain cyanate ester resin. Refer to Example 1 for the production method.
[0057] The application effects of the foregoing embodiments were evaluated, and the results are shown in Table 1. It can be seen from Table 1 that for bisphenol A cyanate ester / epoxy resin systems with different ratios, as long as the mixing temperature (ie the first temperature) and the dispersion temperature (ie the second temperature) are well controlled, the bisphenol The melting amount of type A cyanate, so that part or all of bisphenol A type cyanate is dispersed in the epoxy resin in the form of solid powder, and a one-component RTM epoxy that is solid or semi-solid at room temperature can be obtained. Resin system can meet the requirements of batch setting treatment of dry fabric. When t...
