Abstract

Direction of the vehicle stability is influenced by many things, both in terms of design and the operator of the vehicle itself. The emphasis is one of the influential, it is obvious when the vehicle turns, at which time the position of the focus will turn to change the result of the centrifugal force occurs. Position and magnitude of the centrifugal force that occurs will affect the vehicle slip angle, which will affect the performance of the vehicle. To determine the direction of vehicle behavior, use some concepts: understeer, oversteer, and neutral steer and understeer constant index (Kus). In analyzing the stability of the vehicle used by the calculation analysis Quasi-Dynamic calculation method. With the initial condition is referred to as ideal conditions or conditions Akerman (αr = αf = 0). Outcomes that will result in a critical condition when turning the vehicle with respect to the rear tire slip angle (αr) and the front tire slip angle (αf) that occurred in order to obtain the vehicle oversteer and understeer conditions.Keywords: rear tire slip angle (αr) and the front tire slip angle (αf), understeer,

Abstract

This study aimed to determine the effect of alkali treatment on the impact strength and fracture pattern of bamboo fiber reinforced polyester composites. This composite consisted of polyester resin as a matrix and bamboo fiber as a filler or reinforcement. The alkaline treatment time used was 5% NaOH from 1 hour to 4 hours and to determine the microscopic image of the fracture pattern of the impact test specimen. This study used an experimental method with the dependent variable being the impact strength and microscopic images of the fracture pattern, and the independent variable was the alkali treatment time 1 hour, 2 hours, 3 hours and 4 hours. Specimens were printed using the hand lay-up method. The impact strength was known by performing consecutive tests based on ASTM D 6110-04. Based on the results of the impact test, it showed that the impact strength increased until the alkaline treatment 2 hours ago and decreased at 3 hours, and 4 hours. The highest impact strength was shown in the alkaline treatment of bamboo fiber rope 2 hours with an impact strength value of 1373.89 J/M2. The examination of the microscopic image of the fracture pattern obtained the best fracture in 2 hours alkali treatment with a brittle fracture mechanism.

Abstract

The objective of this study is to find significant differences in impact forces between continuous, discontinuous, and woven fiber type of polyester composites with natural palm fibers and to find out the description of the microfracture structure. This study used experimental methods with independent and dependent variables. The independent variables are continuous, discontinuous, and woven fiber type. Then, the dependent variable was impact forces. Based on the results of tests, show that results from the average score at continuous fiber type = 1.082.88 J/m2, discontinuous = 794.67 J/m2 and woven = 1.427.06 J/m2. The conclusion of this study is that between various fiber orientations was a significant difference in impact forces. The type of woven fibers has a higher value compared to the type of continuous and discontinuous fibers. Discontinuous fiber type has a lower score than continuous fiber type. The fracture model of polyester composite with natural palm fibers showed the mechanism of brittle fracture (brittle) in all test specimens. However, in specimens with the type of continuous fibers and woven, the fracture conditions indicate a brush fracture mechanism.
