Abstract: This paper discusses the application of generative design of mountain bike frames using Solidworks and MATLAB Simulink software. The topic is taken from the problem of the value of the inertial force that occurs in the mountain bike structure due to the dynamic force acting. The mountain bike in this study was made of epoxy carbon composite material in order to get a rigid, strong and light frame. The process is carried out using Solidworks software and analysis using MATLAB Simulink software. This article is an explanation of the bicycle frame design process that occurs due to the assumption of a wavy track. Based on computational studies conducted on MATLAB Simulik, for a load of 90 kg it can be seen that a static load is 1659.1 N and a dynamic load is 36.78 N with a gravity of 9.8 N/m2. Based on the simulation on the track model, it is known that there is a factor of safety of 5.8 with a deflection of less than 1 mm (ie 0.126 mm). The frame of this bike is made of wet laminated composite material made of epoxy composite fiber. Modeling a bicycle frame and how it is used is a major factor in determining the deflection of a bicycle structure.

Abstract: Plant fibers are become an environmentally friendly substitute to glass fibers for the reinforcement of composites, particularly in automotive and civil engineering. The fundamental difference between these two types of fibers is their behavior to the humidity. Plant fibers absorb moisture when they are used as reinforcement in composite materials and drawback their mechanical properties. It is important to analyze hygromechanical behavior of plant fibers in order to treat them before using in composite material as reinforcement. The treatment can be electrically, physically, chemically and other. Indeed, the RC fibers used in this study come from the roots of RC collected in central Cameroon. Fresh ones have been selected for this purpose. Some samples were submitted to hygroscopic ageing in an environmental enclosure of 23%, 54% and 75% relative humidities at 23±1°C and others immersed in distilled water (100%). Hygroscopic ageing is noted by the saturation of the fibers after several weighing on a balance until the constant mass is obtained. This experiment followed steps described by NF EN ISO 483: 2006-01 standard. After that tensile test was done on those saturated individual fibers according to ASTM D 3397-75 standard. Twenty specimens were used to evaluate elastic properties of RC at each hygroscopic condition. The qualitative analysis of behavior curve shows that no matter the relative humidity, the RC fiber presents a toughness behavior and elastic material, characterized by a relatively prevalent viscoelastic area and a great elongation at break. However, we note a decrease of the stress at break and decrease of the elastic modulus for all humidities.
