Abstract
A fixture rod includes a plurality of layers of a reinforcing fiber layer and a plurality of layers of any one of a resin layer, a reinforcing fiber layer having fibers different from those of the reinforcing fiber layer, and a reinforcing fiber layer having fibers obliquely oriented with respect to a fiber direction of the reinforcing fiber layer, in which the plurality of layers are each alternately formed as viewed in a cross-section. The fixture rod reduces damage at the time of fixing with a screw, has high rigidity and high durability against a deformation load, and has greatly improved safety even at the time of breaking.
Claims15
A fixture rod comprising:
- a first plurality of layers including reinforcing fiber layers and a second plurality of layers including resin layers, the reinforcing fiber layers being thicker than the resin layers;
- and
- a cover layer acting as an outer surface of the fixture rod and covering at least a portion of the first plurality of layers and the second plurality of layers, wherein
- each of the first plurality of layers is alternately formed with each of the second plurality of layers so as to be stacked in a direction substantially perpendicular to an axial direction of the fixture rod as viewed in a cross-section taken along a plane perpendicular to a central axis of the fixture rod.
