[Prior art and its problems] Lightness, impact resistance, toughness, moderate flexibility, and creep resistance are required properties of a frame for expanding (stretching) canvas in a falting boat (assembly canoe). There are properties such as lightness, lightness, impact resistance, and toughness are important. That is, it is necessary to reduce the weight in terms of transportation and reduction of the weight of the boat, and on the other hand, it is necessary to have high impact resistance in terms of receiving a strong impact due to a collision or a grounding. When the frame is broken, bent, or deformed during use, the boat functions such as stability and maneuverability will be significantly reduced, and the broken frame will break through the canvas and damage the human body, which poses a problem for safety. . Generally, since the frame of a palo boat is an assembly type and has a structure that is joined by a joint, the frame may be broken, cracked, deformed, etc. by being stepped on or bumped during assembly, disassembly, or transportation. Inconvenience occurs. Especially when the joint is damaged, it becomes difficult to assemble the frame, so the frame is required to have a large toughness. As a canvas expansion frame,
Although plastic pipes such as heat-resistant vinyl chloride and glass-reinforced polyphenylene ether resin and aluminum pipes are used, they are not satisfactory because they have the above problems. That is, since the plastic pipe has a low impact value, there is a problem of breaking and cracking due to impact, and there is a problem that cracking and chipping of the joint portion occur due to poor toughness. On the other hand, in the case of aluminum pipes, it is necessary to make the wall thickness thin in order to reduce the weight and to give flexibility, so it is easy for dents, crushing, and bending to occur due to impact,
In particular, the deformation of the joint part becomes a problem.

The frame of the present invention comprises a pipe made of synthetic fiber reinforced resin. In this case, thermosetting resin such as epoxy resin or unsaturated polyester resin is used as the resin. As the fibers, polyester fibers or vinylon fibers are used.

The synthetic fiber used in the present invention is used in the form of cloth, sleeve, yarn, non-woven fabric and the like. The synthetic fiber reinforced resin pipe according to the present invention is manufactured by impregnating the above-mentioned fibers with a resin to form a prepreg, and using this prepreg, a pipe is formed by a sheet winding method or a filament winding method. It can also be manufactured by impregnating a mandrel wound with fibers with a resin and then curing the resin. The resin content of the prepreg used in the present invention is preferably 30 to 60% by weight in the case of a cloth, yarn or sleeve, and is preferably 40 to 70% by weight in the case of a non-woven fabric. . If the resin content is too high, the toughness of the resulting pipe will be impaired and cracking will occur when nailed. A preferable pipe for use as a canvas expanding frame in the present invention has a pipe wall thickness t defined in a range of 1.0 to 4.0 mm, and a ratio t / d between the wall thickness and the inner diameter d of the pipe. 0.05-2.
It is specified in the range of 0, preferably 0.07 to 1.0. By thus defining the pipe wall thickness t and the ratio of the pipe wall thickness t to the pipe inner diameter R, a frame having excellent mechanical properties such as light weight, nailing resistance, impact resistance, and toughness Can be obtained.

EXAMPLES The present invention will be explained in more detail with reference to examples. In addition, the measuring method of the characteristic test shown below is as follows. Elastic modulus Span = 300 mm, Crosshead speed = 10 mm / m
It was measured by the in-point three-point bending method. Impact resistance The impact value of the pipe set in the IZOD impact tester was measured. Toughness: Tested by the following two methods 1) Using a DuPont type impact tester, set the impact core (top diameter = 1/4 inch) on the pipe and drop the load block onto the impact core to make it into the pipe. The toughness was measured by the weight of the block and the drop height when the pipe was deformed or destroyed by impact. 2) The state of the pipe when a nail with a diameter of 2 mm was driven in was observed.
