Disclosed is a molded article of a composite material, comprising a main body (20) made of reinforced fibers, wherein the main body (20) has at least two opposite side walls (21), and a foaming body (30) is buried in each of the side walls (21). By means of the configuration of two foaming bodies (30), the main body can achieve a high-intensity effect without affecting the weight reduction thereof.
A fiber composite material tire-hooking felly (10). The tire-hooking felly (10) is provided with a main body (20) made of fiber composite material. The main body (20) comprises an inner end wall (21), an outer end wall (22) and two sidewalls (24) connected between the inner and outer end walls (21, 22); two hook portion (26) for hooking a tire (34) protrudes from an outer side surface (224) of the outer end wall (22); the connection line at positions where the outer side surface (224) of the outer end wall (22) is connected with the two hook portions (26) is defined as a reference line L; the outer side surfaces of the two outer end walls (22) are each provided with a brake block (224a); and the connection line of central points (224d) of the two brake blocks (224a) is located between the reference line L and the inner end wall (21). Thus, the tire-hooking felly hardly deforms under the effect of brake.
Disclosed is a fibrous composite frame (10), comprising at least one frame unit (11). The frame unit (11) comprises two members (20), and at least one rod body (12) which is formed by connecting the two members (20). Each member (20) is provided with a foaming body (30) made of a foaming material, and a fibrous composite outer layer (40) which is coated outside the foaming body and is made of a fibrous composite. The fibrous composite outer layer (40) is provided with a junction surface (42), the two members (20) are fixedly connected to each other by means of the junction surfaces (42) of the fibrous composite outer layers (40) thereof, and the two members (20) are symmetrical to each other in shapes in essence by using the junction of the two members (20) as a centre. Therefore, the fibrous composite frame has a low weight, is difficult to break, and easy to manufacture. In addition, the fibrous composite of the frame can be arranged in a relatively easy and dense way.
A fiber compound material felly (10) includes a plurality of arc frame bars (20). Each arc frame bar (20) has a foaming object (30) made of a foaming material, and a fiber compound material outer surface (40), which surrounds the foaming object (30) and is made of fiber compound material. And both ends of each arc frame bar (20) form an engage surface (46) respectively. These arc frame bars (20) are linked by their engage surfaces (46) of the fiber compound material outer surface (40) to form a ring. The link position of two adjacent arc frame bars engage surfaces (46) forms a support surface. Therefore, the fiber compound material felly is not only light in weight but also less prone to be broken.
