“…Fiber serves to strengthen the matrix because the elastic modulus of fiberglass is higher than polyester resin. The addition of volume up to 48 fiberglass caused the stiffness of the composite to increase, according to the mixed rule, adding reinforcement (fibers) can increase the elastic modulus of the composite [12], [8].…”

“…Several studies have examined vibration levels to detect damage to a system or engine component [5], [6], [7]. Other studies have examined the characteristics of composite materials where the structure of the material and the volume fraction of the material affect its mechanical properties [8], [9]. Meanwhile, research on cantilever beams has been investigated including the analysis of the effect of composite structures on fiber-reinforced cantilever beams on vibration characteristics [10], [11].…”

The purpose of this study is to analyze the vibration displacement on fiberglass reinforced plastic beams with variations a number of fibers in the resin matrix. Composite beams was made of fiberglass and polyester resin matrix with a number of fiberglass: 0, 24, and 48. Composite beams was manufactured by hand lay-up method with the unidirectional fiber orientation. The composite beams used have the dimension of length: 500 mm, height: 20 mm, and width: 20 mm. During the experimental test, the beam was vibrated using an exciter motor which was placed at the end of the cantilever support then using a vibration meter, the vibration displacement data (mm) was measured by placing the vibration transducer postions : 50 mm, 250 mm, and 450 mm from the cantilever support. During the vibration test, the vibration displacement data on the vibration meter screen were recorded using a camera recorder and the data was taken 6 times at each of measurement points. The experimental and analysis results show that the value of vibration displacement (mm) decreases when the fiberglass is added to the composite beam, or in other words, the addition of fiberglass provides an increase in the ability of the beam to withstand vibrations. The maximum vibration displacement value on composites with 0 fiberglass: 0.641 mm, then the vibration displacement decreased in composites with 24 fiberglass: 0.506 mm and the lowest displacement value for the composites with 48 fiberglass: 0.395 mm. Whereas for 3 measurement points at positions 5 cm, 25 cm, and 45 cm along the beam for three kind of the composites, the maximum value of vibration displacement value was obtained at the end of beam composites or at 45 cm from cantilever support: 0.735 mm on composite beam with 0 fiberglass and minimum at position 5 cm near the cantilever support with the value of vibration displacement: 0.323 mm on composite beam with 48 fiberglass.

The need for bicycle transportation with strength and aesthetics as well as light weight is increasing, so it is necessary to innovate material technology to overcome these needs. The main components of a bicycle are the frame, wheels, handlebar, and pedals. In addition to the safety factor, what needs to be considered is the weight of the bicycle. Bicycle frame materials are generally made of steel and aluminium. To reduce the weight of the bicycle, the frame material is replaced by using carbon fibre material so that the bicycle becomes lighter and makes the rider less tired. The purpose of the study was to determine the number of layers, fibre direction and the type of carbon and Hybrid (carbon and hemp) used as bicycle frames. Using carbon fibre with plain (P), twill (T), and jacquard (J) types, with the number of layers every three layers and five layers (P3, P5, PH3, PH5, T3, T5, TH3, TH5, J3, J5, JH3, JH5), the tensile test was carried out using the BSEN 10002 standard, the compression test with the ASTM D695 standard and the impact test with the Charpy method using the ASTM E23 standard. Compression and tensile testing using a Taernogroki machine. The test results show that there is an effect of the type of carbon fibre and coating on the stress obtained from the tensile, compressive and impact tests, which show that Twill type carbon fibre is the strongest with stress of 540.60 kg/mm2, 525 kg/mm2 and 0.0157 N/ mm2, while the strongest layer type is pure carbon fibre layer type, and for the number of layers the strongest is five layers.

Carbon Fiber Reinforced Thermoplastic (CFRTP) is drawing attention, currently in practical use, to shorten a manufacturing time and to reduce manufacturing cost. Though investigation for utilizing CFRTP is conducted flourishingly, the manufacturing method of CFRTP having enough performance has not been established yet. High viscosity of thermoplastic matrix disturbs good molding. The effective intermediate material is necessary. In this report, we used UD tape (SHINDO, TP CA143) that is slit from poly-amid film impregnated carbon fiber spread tow. We tried to produce CFRTP tube by using hot-press processing prepreg that is braided by these UD tapes. Braided prepreg consists of braiding yarns and axial yarns. Determination of the mechanical properties of a composite structure is essential to be applied in accordance with its requirements. We prepared three kinds of samples with different numbers of axial yarn and bending properties of CFRTP were determined by bending tests. Bending strength was proportional to the number of axial yarn and a small number of axial yarns showed ductile fracture, whereas a large number of axial yarns showed brittle fracture.
