摘要： Provided is a resin composite material that has more excellent toughness than that of a related-art resin composite material, and hence, while having rigidity, does not undergo breakage even when a certain strain is applied thereto. Specifically, provided is a resin composite material, including: (A) 100 parts by volume of a polyaryletherketone resin having a melt viscosity of from 210 [Pa·s] to 350 [Pa·s] at a temperature of 370°C and a shear rate of 1,220 [1/s]; and (B) 20 parts by volume to 60 parts by volume of inorganic particles. Also provided is a method of manufacturing the resin composite material.

摘要： A dental powder/liquid material-containing preparation accommodation bag, which suppresses entrainment of air in mixing a powder material and a liquid material for dispensing, is provided. A powder material 8 is accommodated in a powder material accommodation chamber 3 of a bag body 2, while a liquid material 9 dissolving the powder material 8 and changing into a pasty form in cooperation with the powder material 8 is accommodated in a liquid material accommodation chamber 4 partitioned from the powder material accommodation chamber 3 by a weakened section 7. The weakened section 7 is ruptured by applying a pressing force to the bag body 2. As a result, the powder material accommodation chamber 3 and the liquid material accommodation chamber 4 communicate, to feed the liquid material accommodated in the liquid material accommodation chamber 4 into the powder material accommodation chamber 3. Then, the powder material 8 and the liquid material 9 changing into the pasty form are pressed within the powder material accommodation chamber 3 from the surfaces of the bag body 2 for dispensing.
