Abstract: A composite material shell having a base plate made of thermoplastic resin and reinforcing fibers and multiple decorative pieces. Each of the multiple decorative pieces is made of a composite material containing thermoplastic resin and reinforcing fibers. An area of each of the multiple decorative pieces is smaller than an area of the base plate, wherein the multiple decorative pieces are non-directionally arranged, are overlapped, and are welded on the base plate whereby the composite material shell provides unique reflection and depth variations of visual effect.

Abstract: A bicycle wheel has a wheel frame. The wheel frame is a hollow and annular frame and is composited by multiple equally sized wheel bars. Each one of the wheel bars has two halves connected to each other to form the wheel bar, and each one of the two halves being made by laminating, heating and forming a thermoplastic prepreg. The equally sized wheel bars are connected to each other to form the bicycle wheel.

Abstract: A press machine has a body, a lower pressing assembly, and an upper pressing assembly. The body has a first driving device, a second driving device, at least one first supporting rod, and at least one second supporting rod. The at least one first supporting rod is rotatably connected to the first driving device. The at least one second supporting rod is rotatably connected to the second driving device. The lower pressing assembly is movably mounted with the at least one first supporting rod of the body. The upper pressing assembly is movably mounted with the at least one second first supporting rod of the body, and is able to move toward the lower pressing assembly.

Abstract: A phosphorescent thermoplastic composite layered structure has at least one layered element. Each one of the at least one layered element has a polymer matrix and a reinforcing fiber combined with the polymer matrix. The polymer matrix includes a thermoplastic resin and a phosphorescent compound. The phosphorescent compound is dispersed in the thermoplastic resin and has multiple particles uniformly distributed inside the thermoplastic resin. The reinforcing fiber is combined with the polymer matrix of the at least one layered element by pressing and heating to form the phosphorescent thermoplastic composite layered structure.
