Abstract

PURPOSE:To provide a light weight roll of high reliability by putting fiber reinforced resin made header members into the end portion of a roll element pipe made of fiber reinforced resin, enclosing into its opening a heat hardening resin formation containing a reinforcement, and sticking this on an element pipe inner surface by means of centrifugal force and hardening this. CONSTITUTION:Fiber of one kind or more than two kinds of organic fiber such as aromatic polyamide fiber and inorganic fiber such as glass fiber, carbon fiber is used as the reinforcement fiber of a roll element pipe 1 made of FRP. Header members 2 made of FRP can be made by combining reinforcement fibers for the element pipe 1, but it is not necessary to have the same fiber as that of the element pipe 1. Putting the header members 2 into the element pipe 1 is carried out by means of adhesion and it is desirable that both are integrated preliminarily. In continuation, an unhardened heat hardening resin formation 5 containing a reinforcement is enclosed into an opening portion between both through the hole 4 of a header member 2 fitted to the end portion of the element pipe 1. By rotating the element pipe 1 at a high speed, the unhardened resin formation 5 is made to stick on the inner surface by means of centrifugal force, and hardening is carried cut by the usual way. The above realized light weight and improves reliability.

As the adhesive, the above-mentioned Sumiepoxy ELA128 mixed with a stoichiometric amount of triethylenetetramine was used, and a carbon fiber reinforced resin header member attached with a metal journal by curing at 80 ° C. for 30 minutes. Two sets were created.

Subsequently, the FRP header member 2 to which the above-mentioned metal journal is attached has a jar on the peripheral portion of the disk.
The same adhesive as that used when attaching the null to the header was applied, fitted to both ends of the carbon fiber reinforced resin roll stock tube, and cured and bonded at 80 ° C. for 30 minutes.

Was enclosed. Here, as the reinforcing material, CS6PB-542 (trade name) manufactured by Nitto Boseki Co., Ltd., which is a glass short fiber, was used. As the vinyl ester resin, 1 part by weight of each of methyl ethyl ketone peroxide and cobalt octenoate is added to 100 parts by weight of trade name: Lipoxy R806 (novolac type vinyl ester) manufactured by Showa Highpolymer Co., Ltd. Was used. In the vinyl ester resin containing the glass short fibers, the weight ratio of the glass short fibers was adjusted to 30%.

Subsequently, a roll in which the vinyl ester resin containing the glass short fibers is enclosed in a FRP header member is attached to a lathe, and the glass short fibers and the vinyl ester resin are rotated at about 400 rpm for 10 minutes to roll the FRP rolls. After adhering to the inner surface of the raw tube, it was left at room temperature for 24 hours to cure the resin. Then, the FRP header-member was heated at 80 ° C. for 30 minutes to post-cure the resin.
