にとが行なわれ−（いる。(Prior Art) In conventional fiber-reinforced plastics, reinforcing fibers are regularly arranged in one direction or two or more directions, and a thermosetting or thermoplastic synthetic resin (referred to as plastic in this specification) is added to this. By impregnating and avoiding curing, molded products of various shapes such as roots, cylinders, etc. can be made into I! lJ construction 1
Nito is being done.
第３図は母相プラスチック１内に強化繊維２を〜ＩＪ向
、すなわら、Ｚ方向に埋ｕｌ到た例を示している。FIG. 3 shows an example in which the reinforcing fibers 2 are embedded in the matrix plastic 1 in the ~IJ direction, that is, in the Z direction.

がそれぞれ講じられている。In this case, in order to improve the strength of fiber-reinforced plastic, it is necessary to strengthen it! Increasing the strength of Im and the matrix plastic itself, surface-treating the reinforcing fibers to increase the bonding strength with the matrix plastic, selecting the optimal content of reinforcing fibers, and increasing the porosity and d3J. It is important to reduce this, and various measures have been taken to achieve these goals.

待できない。(Problems to be Solved by the Invention) However, in the conventional fiber-reinforced plastic described above, although it is possible to improve the strength in the direction in which the reinforcing fibers are arranged,
In other words, in the example shown in FIG. 3, the tensile strength and shear strength in the X and Y directions are almost determined by the strength of the matrix plastic itself, and oil reinforcement by the reinforcing fibers can hardly be expected.

とができないという問題点があった。On the other hand, in general structural members, multiaxial stress is generated internally depending on their shape and cylinder conditions, but as is clear from the above, conventional w41! The shear strength of reinforced plastics is significantly lower than other strengths, so the overall strength of molded products made of fiber-reinforced plastics is limited by the tensile/compressive strength and shear strength in directions other than the one direction of the reinforcing fibers. In many cases, the overall strength of the fiber-reinforced plastic deck cannot be sufficiently improved even with optimal design, which is a problem.
