Embodiment 1-1

[0086] As the (a1) component, 40 parts by mass of the product name Primaset PT-60 (manufactured by Lonza Corporation) and 20 parts by mass of the product name Primaset PT-30 (manufactured by Lonza Corporation) of a novolak type cyanate resin, and 40 parts by mass of the trade name Primaset BA-200 (manufactured by Lonza Corporation) of bisphenol-type cyanate resin, and 0.06 parts by mass of Co(acac) as the component (a2) 3 3 parts by mass of polyethersulfone (trade name ULTRASON E 2020P SR MICRO, manufactured by BASF Corporation) as the component (a3) ​​was mixed with a planetary mixer to prepare the resin composition (a), and then coated on the release paper A precursor film is thus obtained. Next, a carbon fiber with a tensile modulus of elasticity of 780 GPa (trade name XN-80, manufactured by Nippon Graphite Fiber Co., Ltd.) was made into a unidirectional sheet, and the above-mentioned precursor film was heated and pressed, and immersed in the unidirectional sheet. In the s...

[0113] Using the resin composition (a) prepared in Example 1-1 and the carbon fibers (CF) shown in Table 2, CFRP sheets PPG-A and PPG-E shown in Table 2 were produced. Next, by winding them around a mandrel, a prepreg having a laminate structure shown in Table 3 was manufactured. Next, it is heated and cured under the condition of 180°C×4 hours to manufacture a image 3 Dimensions shown are for a manipulator with an open cross-section and an overall length of 2150 mm. The following bending rigidity test was performed on the obtained manipulator. The results are shown in Table 3.

[0114] It should be noted that, in Table 3, "0°" of the CF orientation angle means that the carbon fibers are oriented in the length direction of the manipulator, and "0° / 90°" means that the carbon fibers are oriented in the length direction and the direction perpendicular to the length direction.

Abstract

Provided are a carbon-fiber-reinforced composite material having a low saturated water absorption and excellent TML, CVCM, and heat resistance, a robot hand, and a prepreg suitable therefor. The prepreg includes a CFRP sheet composed of resin composition (a) containing 100 parts by mass of cyanate ester resin (a1) having in its molecule not less than 2 cyanate groups, 0.01 to 0.5 parts by mass of metal coordination catalyst (a2), and 1 to 20 parts by mass of thermoplastic, toughness enhancer (a3), and carbon fibers (b) containing carbon fibers (b1) having a tensile elastic modulus of not lower than 450 GPa. The prepreg is useful for a supporting section of a robot hand.

Description

technical field [0001] The present invention relates to a product that has a particularly low saturated water absorption, is excellent in total mass loss (Total Mass Loss: TML), collected condensable volatile matter (Collected Volatile Condensable Material: CVCM), and heat resistance, and is also excellent in deformation resistance such as bending rigidity carbon fiber reinforced composites, manipulators and prepregs for them. Background technique [0002] In the industrial world, there is a demand for fiber-reinforced composite materials that are lighter, tougher, and have high heat resistance, impact resistance, and deformation resistance. For example, there is a demand for fiber-reinforced composite materials that can withstand long-term use under severe conditions, such as robots used in various industrial manufacturing sites, high-speed rotating rollers used in plate making and printing, and the aerospace industry. .
