Abstract

many researches these days are conducted on new materials development and processing to vital products. These materials include among others mostly composite from renewable materials. This is a major step towards replacing the conventional materials such as metals in daily usage so as to enhance sustainability. This paper presents the design analysis and thickness optimization of cattle horn - plastic composite chair seat. The process involved developing a solid model using solid modelling software (Pro/E), assigning the material properties of the composite to the solid model and then evaluating the performance during operation. The optimum thickness of the chair seat was then evaluated based on load and minimum weight requirements. The maximum stress experienced during loading was evaluated to be 1.148 N/mm2 , the sensitivity study showed that the maximum stress reduces with increase in the thickness of the chair scat. The optimum thickness required to sustain the load during operation was evaluated to be 4.118 mm. Validation of the design analysis was conducted using the optimized model. The validation showed that the maximum operating stress is 30.152 Mpa which is less than 50 % of the flexural strength (65.89 Mpa) of the composite and thus showed that the designed chair seat is safe.
