Aerospace Composite Material Methodology: A Detailed Research Proposal

This research proposal investigates the methodology for creating a composite material suitable for aerospace applications, focusing on a polymer matrix filled with dielectric and magnetic materials. The aim is to achieve desired mechanical properties, microwave absorption capabilities, and tunability. The proposal explores using MWCNT fillers with strontium ferrite or Ni-Zn ferrite, employing sol-gel and melt blending techniques. The research builds upon existing literature on materials like SMCNP, CPAN NF/MNP hybrid membranes, and CNT/PLA composites, drawing inspiration from stealth technology and natural rubber-ferrite mixtures. The ultimate goal is to identify a composite material with superior properties for aerospace applications through process refinement and filler distribution optimization. Desklib offers a wealth of similar student-contributed documents and study resources.

Research proposal
Aim of the research
The aim of the proposed research is to investigate the methodology to yield a composite
material to meet the demands of the aerospace applications.
Scope of the research
Specifically the materials selected for synthesis will be a polymer and filler made of dielectric
and magnetic materials. The final composite material is expected to possess desired
mechanical properties along with capacity of
 Microwave absorbing frequency
 Suitable mechanical properties for aerospace applications
 Tunable and switchable too
Issue/Problem
The issue or combination is to track a suitable polymer along with filler material of required
properties to yield composite material. Also required is to find the suitable methodology for
synthesis.
Proposal
The proposed research is the investigation of the possible composite by MWCNT fillering
with strontium ferrite or alternatively employing Ni-Zn ferrite filler materials. Sol-gel and
Melt blending with compatiblization methods are proposed respectively. By varying the
distribution of the filler materials as well as refining the process used for the properties of the
final composites can be tuned as needed. Material with relatively better properties will be
finalized for the intended aero- applications.
Literature review/Supporting evidence
SMCNP silver particle modified carbon nano tube paper can be a typical composite that
meets the current demands. The final composite has the necessary microwave absorbing
capacity and also has the necessary mechanical properties as needed for the intended
application. Facile method is employed for generation of the same[1]. CPAN NF/MNP
hybrid membrane is another possible aerospace material prepared from facile methods that
can be of use in the current case[2].CNT/PLA (polyactic acid) based composite materials are
already there prepared by 3D printing methods and will meet the demands of aerospace
applications; modification of CNT in these substances using silver particles modification can

be a good proposal to investigate better properties[3]. Stealth technology at present
employing grapheme based carbonaceous materials in making composites with RAM (Radar
absorbing materials) with electromagnetic properties as needed for the current requirements.
3D printing is being employed for the same [4][5][6][7]. Natural rubber mixed with ferrite
fillers is also reported with desired properties in literature [8].
