摘要： Polyamide particles including polyamide and having a water absorption rate of 0.5 to 2.5 wt. % are prepared to improve toughness of a cured product of a curable resin. The polyamide may be a semicrystalline polyamide. The polyamide has a glass transition temperature of approximately 100 to 150° C. The polyamide may have an alicyclic structure. The polyamide particles of this invention have an average particle size of approximately 5 to 40 μm and a specific surface area determined by the BET method of approximately 0.08 to 12 m2/g. The polyamide particles of the present invention may also be spherical and have an average particle size of approximately 15 to 25 μm. Furthermore, the polyamide particles of the present invention may have an exothermic peak in a temperature range between the glass transition temperature and a melting point of the polyamide upon heating the polyamide particles at a rate of 10° C./min by differential scanning calorimetry (DSC).
