L程度の連続繊維が用いらhている。FRP spring plate is reinforced 1. The reinforcing fibers are made by hardening them with wood, and the reinforcing fibers are, for example, 10 to 25 μm in diameter.
Continuous fibers of about L length are used.

tシている。by the way. According to the research carried out by the inventors, in terms of bow length strength, using thinner reinforcing fibers is better than using thicker reinforcing w.
It has been found that thick reinforcing fibers have higher durability than those using fibers, and are more advantageous in terms of compressive strength. In addition, thick reinforcing fibers require fewer bundles and doublings, so they have better resin permeability and alignment than thin reinforcing fibers, and also take longer to harden, making them ideal for high-speed molding.
There is a t-shi.

久性と圧縮特性に愛れたばね板が得られることになる。Therefore, when molding a single FRP spring plate, for example, if the spring plate is formed with thin reinforcing fibers on the tensile stress side 11, and thick reinforcing fibers are placed on the compressive stress side, it will be durable. This results in a spring plate with excellent elasticity and compression properties.

After making the first wall of the tree 11 and making it the front wall, press it against the mold C and form it.When molding one spring plate, strengthen the thickness of the two types or more. , when using Yawei,
As the number of rovings and resin increases, the rovings become tangled and become sticky during maintenance, and the trouble of monitoring the resin tank increases, so it is difficult to form a single spring plate. It is desirable to use as much as one type of reinforcing fiber.

3よりも耐久性が重視される。In the wax leaf spring device shown in FIG. 2 constructed as described above, when a downward load is applied to both ends of the main spring plate 10, the main spring plate 1 gradually lowers as the deflection of the main spring 1 increases. The direction (compressive stress side) comes into contact with the auxiliary spring plate 3, resulting in a nonlinear characteristic in which the spring constant increases. Therefore, durability of the main spring plate 1 is more important than that of the auxiliary spring plate 3.

、成形性が良く、陵産にノ旙するものである。However, in this example, as mentioned above, the main spring plate 1 is molded using only thin reinforcing fibers, and the auxiliary spring plate 3 is molded using only thick reinforcing fibers, so these are overlapped. When used as a plate spring device, the durability of the main spring plate is improved by the thin reinforcing fibers, and the individual spring plates can be molded using the same type of reinforcing fiber, and the auxiliary spring plate 3 has thick reinforcement 4. .. Because it can use fiber, it has good moldability and is suitable for production in Ling.

It is characterized by being molded. Therefore, according to the present invention, as a spring plate car body, the reinforcement of the same type of material is used. ,
In addition to being able to be molded efficiently, the thickness of the reinforcing fibers used in each spring plate can be changed depending on the amount of stress used (the progress of mental strength, etc.), thereby creating a highly durable stacked leaf spring device. In addition, since thick reinforcing fibers can be used for some of the spring plates, the moldability is further improved, and it is possible to provide an FRP retaining plate spring device suitable for kumamu.
