[Technical Field of the Invention] The present invention improves water resistance and elongation at break without impairing heat resistance, and also improves strain energy release rate (G IC ), which is one of the extremely important properties for primary structural materials for aircraft. This invention relates to a thermosetting resin composition having a very large amount of heat. [Prior art] Recently, composite materials obtained by impregnating carbon fibers with resin and curing them, so-called carbon fiber reinforced plastics (hereinafter referred to as CFRP), have been developed.
is being widely used as a primary structural material to reduce the weight of aircraft. Conventionally, epoxy resin compositions have been mainly used as resins for impregnating carbon fibers, and especially when heat resistance is desired, epoxy resins such as tetraglycidyldiaminodiphenylmethane (TGDDM) and diaminodiphenyl as a curing agent have been used. Epoxy resin compositions with added sulfone (DDS) and BF 3 -monoethylamine complex (BF 3 -MEA) have been widely used. However, this
TGDDM/DDS-based epoxy resin compositions have excellent initial heat resistance and adhesion with carbon fibers, but they have drawbacks such as a significant decrease in heat resistance due to moisture absorption, extremely high hardness, and low elongation. be. Epoxy resin compositions that use phenols as curing agents are also used, but these have relatively good water resistance, but have drawbacks such as low elongation and problems with adhesion to carbon fibers. There is. Furthermore, an epoxy resin composition using resorcinol as a curing agent has been proposed, but this also results in a cured product with high hardness and has drawbacks such as low elongation. As described above, conventional epoxy resin compositions are not satisfactory for use as primary structural materials for aircraft, requiring high heat resistance and elongation of 2% or more. [Object of the Invention] The present invention has excellent heat resistance, water resistance (lower glass transition point (Tg) especially after moisture absorption), and elongation at break, as well as strain energy release rate (G IC ).
An object of the present invention is to provide a thermosetting resin composition which has a large elongation and is suitable for impregnating high elongation carbon fibers. [Structure of the Invention] Therefore, the present invention provides a bismaleimide triazine resin comprising 95 to 85% of a cyanate ester and/or a prepolymer thereof and 5 to 15% of a bismaleimide and/or a prepolymer thereof, and having a molecular weight of 1000. ~1500 and 1900~2400 9/1
A thermosetting product characterized by blending 5 to 20 parts by weight of a 0-cresol novolac epoxy resin with a melting point of 75 to 95°C to 95 to 80 parts by weight of a mixed resin mixed at a weight ratio of ~7/3. The gist is a synthetic resin composition. Hereinafter, the configuration of the present invention will be explained in detail. The mixed resin used in the present invention consists of 95 to 85% of cyanate ester and/or its prepolymer and 5% of bismaleimide and/or its prepolymer.
~15% bismaleimide triazine resin with a molecular weight of 1000 to 1500 (hereinafter referred to as resin A) and one with a molecular weight of 1900 to 2400 (hereinafter referred to as resin A).
Resin B) is mixed in a weight ratio of 9/1 to 7/3. In addition, the above-mentioned cyanate ester and bismaleimide include this and diaminodiphenylmethane,
It is also possible to use a mixture or combination of aromatic amines such as diaminodiphenylsulfone. The thermosetting resin composition of the present invention is based on this mixed resin.
5 to 20 parts by weight of an 0-cresol novolak epoxy resin having a melting point of 75 to 95°C is blended to 95 to 80 parts by weight. The reason for specifying the composition in this way is as follows. Bismaleimide triazine resin is known as a resin with good heat resistance, and it is also known to be used in combination with an epoxy resin. However, bismaleimide triazine resins with high heat resistance require a curing temperature of 200°C or higher and have extremely low elongation. Therefore, we investigated how to improve curability, heat resistance, moisture resistance, and elongation in a well-balanced manner, and found that cyanate ester and/or its prepolymer contained 95 to 85% and bismaleimide and/or its prepolymer contained 5 to 15%.
The present invention employs a bismaleimide triazine resin consisting of: The reason for this blending ratio in this resin is that if the content of bismaleimide and/or its prepolymer is less than 5%, the heat resistance will deteriorate, and if it exceeds 15%, the curing temperature will be high (over 240°C) and difficult to handle. Because it will be. In addition, the present inventors have found that the resin A corresponds to the above resin A.
BT-2160 (cyanate ester/bismaleimide = 9/1, molecular weight 1200, manufactured by Mitsubishi Gas Chemical), BT-2170 (cyanate ester/bismaleimide = 9/1, molecular weight 2100, Mitsubishi Gas Chemical), which corresponds to the above resin B Chemical), ESCN-220F (melting point 80℃, 0-cresol novolac epoxy resin, manufactured by Sumitomo Chemical),
and ESCN-220HH (melting point 90°C, 0-cresol novolak epoxy resin, manufactured by Sumitomo Chemical) were used to measure the physical properties of resin compositions obtained by mixing these in various weight proportions. The results are shown in FIG. In Figure 1, E b is the flexural modulus during the three-point bending test (Kg/mm 2 , cured at 180°C for 2 hours),
Min Vis is DMA (dynamic mechanical
The minimum viscosity (cps) during curing by
Tg is the glass transition temperature (℃) determined by TMA (thermo mechanical analysis), ε b is the elongation at break of the surface during the three-point bending test, Hot Wet is 80℃ 100% RH7
The results are shown at 121°C after 1 day. As shown in the left half of Figure 1, ESCN—
BT―2160 and BT― with the amount of 220F constant.
It can be seen that when the amount of 2170 is varied, the range of a is preferable in terms of physical properties. This range of a is such that the weight ratio of resin A and resin B is from 9/1 to
It corresponds to 7/3. Also, as shown in the right half of Figure 1, BT
It can be seen that when the amounts of -2160, BT-2170, and ESCN-220HH are changed, the range b is preferable in terms of physical properties. The range of b is when 5 to 20 parts by weight of a 0-cresol novolak epoxy resin with a melting point of 75 to 95°C is blended to 95 to 80 parts by weight of a mixed resin formed by mixing resin A and resin B. Equivalent to. Therefore, in the present invention, the constituent components and their amounts are defined as described above. In addition, additives such as a curing accelerator may be added to this thermosetting resin composition as necessary.
This thermosetting resin composition can be sufficiently cured under curing conditions of 180° C. for 2 hours. [Effects of the Invention] As explained above, the thermosetting resin composition of the present invention is made by blending the mixed resin and a 0-cresol novolak epoxy resin with a melting point of 75 to 95°C in a specific ratio. Therefore, water resistance and elongation at break can be improved without compromising heat resistance, and strain energy release rate (G IC ) can be improved.
Suitable for impregnating high elongation carbon fibers,
Therefore, it is extremely useful for applications such as primary structural materials for aircraft.

的を達成し得るものではない。[Table] As is clear from Table 1 above, the resin composition of the present invention is superior to conventional ones in terms of strain energy release rate (G IC ) and ILSS. Comparative Example 4 BT-2160 72 parts by weight BT-2170 18 parts by weight ELM-434 10 parts by weight Dicumyl peroxide 0.2 parts by weight Zinc octylate (Zn content 1.8%) 0.02 parts by weight Measurement of physical properties of the resin composition with the above formulation did. The results are shown in Table 2 below.
