Composite Materials for Commercial Equipment
Introduction to Proposal
The area of research is important because it deals with recycling of plastics towards the
production of composite materials that are stronger and lighter than its constituents.
Introduction
Composite materials are material systems consisting of two or more physically instinct
phases that produce total characteristics different from its constituents (Groover, 2010). The
properties of the composite materials are always superior and that is why they are of importance
in commercial equipment. Composites are always designed in such a way that they are strong
and stiff but very light in weight. This gives the materials strength-to-weight and stiffness-toweight ratios that is greater than aluminum, concrete or steel (Groover, 2010). It is these
properties that make composite materials desirable in commercial applications.
Background
Composite materials have been used in various commercial areas. One of the places of its
application is in Glass Fiber Reinforced Plastic (GRP). In this application, the compressive
strength of cement and concrete composites with 5% to 50% GRP waste powder ranged from 37
to 19 N/mm2 (Asokan, Osmani, & Price, 2009). Similarly, Correia, Almeida, and Figueira (2011)
also confirmed that composite materials in the form of Fiber Reinforcement Polymer (FRP) are
increasingly being used in construction industries. There is a wide range of production of FRP
products used in the strengthening of strips and sheets, sandwich panels, piping, molded planks,
and reinforced bars (Correia et al., 2011). It is the desirable properties of the composite materials
that have made them be used by many construction industries.
Body of the Work
This research paper will discuss how plastics can be recycled towards the production of
composite materials used in pavement and construction of buildings. The paper shall also discuss
how these composite materials are stronger than current cement and concrete that are used in
pavements and buildings.
Conclusion
Composite materials have gained application in commercial areas because of their
desirable properties. Composite materials can help in the achievement of several properties that
are not achievable with ceramics, metals, and polymers alone. However, the properties of
composite materials do vary depending on the measured directions. Also, many composite
materials in the form of polymers are always susceptible to chemical attacks.
