Abstract
The present study investigates mechanical, thermal, and tribological characteristics with the influence of novel composite
material of perforated polyethylene terephthalate (PET) polymer, distinct natural fibre, and vinyl ester matrix produced by
compression moulding technology. The primary objective of this study is to identify and influence the strength of vinyl
ester resin bonding features of three distinct natural fibre sources: banyan, snake grass, and pineapple with recycled PET
plastic bottles polymer composites. The natural fibre is undergoing chemical treatments using NaOH (7% alkali) in order to
remove the impurities and enhance the strength of the composite material. The mechanical characteristics of the produced
composites (PC1, PC2, PC3) were assessed using tensile, flexural, and impact tests. The study also encompasses an inves-
tigation of thermogravimetric analysis conducted on natural fibre/PET/vinyl ester composites, demonstrating the impact of
distinct fibre with PET polymer on thermal characteristics. Moreover, specific wear rate and coefficient of friction analysis
explore the distinct character of developed composites. Using natural fibre reinforced/vinyl ester composites in conjunction
with PET offers a promising avenue for achieving lightweight structural applications due to the PET composite's favourable
mechanical properties and heat resistance.

1 Introduction
Composite materials have witnessed exponential growth
in various industrial applications ranging from aerospace
to automobile and construction. Composites made from
manufactured materials typically include synthetic fibres
like glass or carbon, which are strong but harm the environ-
ment [1]. As global sustainability concerns growth, there
is an increasing focus on developing eco-friendly materi-
als that deliver performance and have a minimal environ-
mental impact [2]. Natural fibres extracted from plants
have emerged as a promising alternative to manufactured
fibres, which are abundant, renewable, and have favourable
mechanical properties. Additionally, using recycled plastics
with matrix materials can contribute to waste management
efforts [3]. PET is a widely used plastic, especially in pack-
aging and textiles, but it is also a major contributor to plas-
tic pollution. Valorizing PET helps in reducing waste and
mitigating environmental pollution by recycling and reusing
materials rather than sending them to landfills or incinerat-
ing them. Valorizing PET or fibres often involves developing
