The study investigates the dry-sliding wear behaviour of polyester/carbon fibre reinforced polymer (CFRP) composites using a Taguchi-GRA combinatorial approach with two output responses: wear and frictional force. Load (L), sliding distance (D), sliding velocity (S), and fibre reinforcement percentage (R) are treated as input factors, and experiments are planned through a design of experiments strategy. Principal component analysis (PCA) supports the weighting calculation in GRA. ANOVA results indicate that load (L) and reinforcement percentage (R) exert the greatest influence on wear behaviour, and a wear mechanism discussion is supported by SEM morphology.

The present work has put forward an attempt to study the dry-sliding wear behaviour of CFRP composites followed by implementation of Taguchi-GRA combinatorial approach for the two output responses namely, wear and frictional force. Load (L), sliding distance (D), sliding velocity (S), and percent of fibre reinforcement (R) are considered as input conditions and the experiments were planned using design of experiments. In addition, Principal Component Analysis (PCA) has taken into consideration for the weights calculation in GRA. An elaborate study on the implementation these methodologies on the combined behaviour of wear and frictional force has been presented. Furthermore, ANOVA data is analysed, it appears that both the load (L) and the percent reinforcement (R) has greater effect towards the wear behaviour. A detailed discussion on wear mechanism has also been presented with a support of SEM morphology. ABSTRACT 1. INTRODUCTION Over the course of the last few decades, the innovations in the material science have undergone a substantial change, and along with it, the requirements for composite materials in multiple disciplines have increased. Polymers have recognized as one of the most significant categories of innovative materials. Because of their individual characteristics, such asa high strength-to-weight ratio (S/W ratio) and high stiffness, the number of applications for polymer composites in automotive industries has been steadily increasing [1] more specifically in the domains of panels, belts, hoses and etc. Some of the research [2, 3] has been attempted to increase the lifespan of commercial polymers by enhancing the mechanical and tribological properties of the materials through the addition of hard ceramic particles at the micro and nano level. On the other hand, the durability of a component is also an essential requirement that one should take care during the process design and development. In this regard, polyester is a good option for increasing the product's potential lifespan as such it was unaffected by the effects of moisture, or humidity [4] . Few attempts have been made with polyesters are commonly as matrix materials, and to increase the mechanical and tribological properties with various reinforcement like glass, aramid and carbon fibres [5 , 6] . Venu et al. [7] studied the thermal behavior of jute and carbon fibres as reinforcements in polysters. Mir and Charoo [8] studied the usage of carbon fibres in PEEK (Poly-EtherEther-Ketone) for orthopedic applications. Therefore, the addition of Carbon fiber is remarked as one of the significant and novel attempt in the recent years to accomplish an intriguing balance of mechanical attributes, S/W ratio, and low density as reported by Wang and Gao as well as Messana et

FAQs

What materials and outputs are studied in this work?

The work studies polyester/carbon fibre reinforced polymer composites under dry-sliding conditions. It optimizes two output responses: wear and frictional force.

Which factors are considered as input conditions in the experiments?

Load (L), sliding distance (D), sliding velocity (S), and fibre reinforcement percentage (R) are used as input conditions for the design of experiments.

How are weighting and optimization handled using Taguchi-GRA and PCA?

Principal component analysis (PCA) is used to calculate weights within the GRA framework, while the Taguchi-GRA combinatorial approach guides multi-objective optimization of the responses.
