Abstract
According to one implementation, a blast treatment method includes: setting a blast treatment condition for a composite material to make a degree of activation on the surface of the composite material within an appropriate range, based on reference information; and manufacturing a blast treated product by the blast treatment of the composite material under the blast treatment condition set to make the degree of the activation within the appropriate range. The reference information shows a relation between a strain amount of a test piece caused by blast treatment under a predetermined blast treatment condition and a degree of activation on a surface of a sample of a composite material by blast treatment, for activating the surface of the sample before painting or bonding, under the predetermined blast treatment condition.
