Composite are occupying the place of conventional materials by meeting the requirements of
industries of not only in aerospace sector but in automotive, mechanical, space, construction
industries and Bio medical applications, but the desire of achieving the higher modulus to density
ratio always remains starved as it requires the maximum output in minimal consumption with better
life expectancy to find the economical means of utilizing the technology for different applications. In
need of which researches have been emerged to obtain the hybrid composites by the combination of
multiple types of materials to obtain the desired strength with less density. For most of the
applications of Automotive, Aerospace and biomedical applications, the flexural strength plays a
crucial role as the structure continuously or repeatedly subjects to point or uniform load, therefore a
study to evaluate the flexural strength by using different types of matrix material and also to optimize
the thickness of lamina is done, and comparisons are made by using different categories of matrix
material on different thickness of laminates.

Increase in demand of advanced
materials to satisfy the requirements of aerospace
and automotive industry viz. high modulus to
density ratio, leads to the research in composite
materials where an attempt is made to study the
properties of composite materials by composing
the different materials together to obtain the
desired properties by reducing the weight as
much as possible. Here an attempt is made to
study the behavior and tensile properties of
Hybrid polymer composite material by composing
E-glass fibres, carbon fibres and graphite with
epoxy resin 5052. By the variation of thickness.
Tensile strength of hybrid composite is observed
for each thickness and is optimized and compared
with the properties of standalone glass fibre
reinforced composites for the same variation of
thickness. The comparison represents the
enhancement of tensile strength and cost
effectiveness by the introduction of multiple
materials (Hybrid composites)

Highly fluorescent silver nanoparticles (Ag-NPs), soluble in a ferroelectric host of polymer molecules such as poly(vinylidene fluoride(PVF2), have been created in the form of nanofluids. The content of Ag-NPs (flocculates)is varied in steps 0.1–0.2 wt% up to a value of 5.0 wt% in tailoring a broad green emission band over 520–620nm out of a hybrid percolation Ag–PVF2 composite. A maximum intensity arises in this band at as small a percolation threshold as 0.1wt% Ag-NPs. It contains three distinct bands of peak values 541, 565, and 582nm in an Ag-NPs tunable response
of the localized surface plasmons. The emission-dependent anti-Stokes excitation spectrum contains a similar group of three bands 348, 401,
and 421 nm. For Ag-contents above 0.1 wt%, interdependent intensities in the emission and excitation bands drop rapidly by as much as five times, conferring a metal–polymer percolation network. The results open wide applications for biological labels and light emitters using such nanofluids.
