SOLIDIFIED POWDERY PARTICLE, STRUCTURAL MEMBER WITH HIGH RESISTANCE TO FLEXURAL STRENGTH, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide solidified powdery particles remarkably improving resistance to flexural strength of a structural member by filling the powdery particles in the structural member almost free from increase of mass for solidification and to provide a method for producing the same.

SOLUTION: The invention relates to the solidified powdery particles comprising first powdery particles filled in a state in which each adjacent particle is contacting each other and foamed articles of thermoplastic resin filling gaps of the first powdery particles and fusion bonding the surface of the first powdery particles to bond each first powdery particles. The member 4 with high resistance to flexural strength comprises a skeleton structural member 5 with thin wall and the first powdery particles 2 filled in the skeleton structural member 5 with thin wall in a state in which each adjacent particles contacts each other and the foamed article 3 of the thermoplastic resin filling the gaps between each first powdery particles and fusion bonding on the surface of the first powdery particles to bond each first powdery particles and bonding the inner wall of the skeleton structural member with the first powdery particles.
