摘要： A method for evaluating the compatibility of a thermosetting resin composition containing at least two kinds of resins and an inorganic filler, the method including the following steps 1A and 2A: Step 1A: a step of obtaining a reflected electronic image of the cross section of a cured product of the thermosetting resin composition using a scanning electron microscope at an observation magnification of 50 to 250 times; and Step 2A: a step in which, in the reflected electronic image, a phase-separated resin region is referred to as a separation part and the remaining region is referred to as a non-separation part, and the image is binarized such that the separation part has one value and the non-separation part has the other value, and the area ratio of the region of the non-separation part of the resultant binarized image to the total region of the binarized image (area of the region of the non-separation part×100/area of the total region of the binarized image) is calculated as the area ratio Rw of the non-separation part.

摘要： A press-molded product includes: carbon fibers having a weight average fiber length of 1 mm or more; a polyamide-based resin (X); and a polyarylene ether-based resin (Y). The carbon fibers include carbon fiber bundles. The polyamide-based resin (X) and the polyarylene ether-based resin (Y) form a sea-island structure inside and outside the carbon fiber bundles. In the sea-island structure, one of the polyamide-based resin (X) and the polyarylene ether-based resin (Y) forms a sea phase and the other forms an island phase having a particle diameter Dr of 0.05 μm or more and less than 50 μm.
