PURPOSE: To obtain a superhigh-strength material by trapping its bonding power into the lattice structure of crystal in material and substance and generating such bonding power proportional to distance as is shown in the trapping theory of quark.

CONSTITUTION: Atoms or molecules in substance are bonded by exchanges of electrons or electromagnetic force. Since electromagnetic force is inversely proportional to the square of distance, it is easily cut by deformation due to external force and thereby material is destroyed. When this bonding power is trapped into a material such as a latticelike tube, such bonding power propor tional to distance as is shown in the trapping theory of quark in high-energy physics is generated and the material having toughness extremely different to the conventional material is obtained. In the concrete, lines of magnetic force can be trapped into the lattice structure with a tubular shape e.g. by burying high-temp. superconducting substance into the parts between the gaps of the lattice structure.
