対処は行われていない。C. Prior Art] Various properties of fiber-reinforced laminates exhibit large anisotropy depending on the direction of the reinforcing material, and improving the properties in the non-reinforced direction has become an important issue. Conventionally, this anisotropy has been overcome by either randomly orienting the reinforcing material within a plane, or by creating a multilayer laminate in which the fibers have different orientation directions in various layers. The common technique was to make it essentially isotropic. However, as the application of composite materials progresses, the number of products with complex shapes and thick walls increases.
In particular, layer shear strength has become a problem. Although measures have been taken to deal with the anisotropy in the in-plane direction as described above, measures have not been taken to deal with the anisotropy in the direction perpendicular to the laminated plane.

十分に生かし得ないという問題点があった。In this way, although whiskers are oriented between layers of long fiber layers even in the conventional technology, most of these whiskers are oriented only in the in-plane direction of the laminated surface of long fibers, and the glabella strength is There was a problem in that the fiber orientation to improve the fiber orientation, that is, the orientation in the direction perpendicular to the long fiber lamination plane, was not done, and the reinforcing effect of the reinforcing material could not be fully utilized.
