Abstract
This thesis deals about the design and development of leaf spring for a Lifan 1020 mini truck
car using hybrid composite materials. The aim of this work is to replace the existing steel leaf
spring material with a mono laminated hybrid composite material. The dimensions (accept the
thickness) and load bearing capacity of composite leaf spring is the same as steel leaf spring.
Thus, the objective of this work is to reduce the weight of product while upholding its strength.
Therefore, to solve this kind of problem, composite materials are the appropriate type of
materials that can be customized according to the application types and load.
The thesis describes the development and characterization of Kevlar
49
and E- glass hybrid
composite materials with general purpose epoxy. To characterize the material properties tests,
such as flexural, compression and tensile strength was carried out. In the experimental test
result material “B” has maximum tensile strength and material “A” has maximum compressive
and flexural strength test. In addition, hyper work software was use to show the ply stacking
(laminated) sequence of composite materials.
The total deflection and equivalent (Von- misses) stresses distribution applied both on steel leaf
spring and composite leaf spring were done using ANSYS 18.2 workbench and were compared.
The solid modelling of leaf spring was done on Solidwork 18 and was analyzed using ANSYS
software. Finally, according to the static analysis results, the study revealed that hybrid mono
composite leaf spring provides better performance than that of the current conventional steel leaf
spring of Lifan 1020 mini truck car.
