Quality raw material in Pultrusion Process
Pultrusion can be formally defined as that
manufacturing process that converts fibre reinforcements
and resin matrices into finished composite parts. Its USP of enabling
continuous production in a highly automated and low-labor scheme by making use
of a heated die to give a certain shape to the composite part sets pultrusion
apart from other processes. This is what makes pultrusion a process with the
best productivity and cost ratio and hence is widely used in the composite
industry.
Does the quality of raw material affect the pultrusion
process?
Pultrusion process has developed in several ways over
time not only in terms of the process itself, however, in terms of usage of raw
materials too, especially of quality raw materials like fibre reinforcements and
polymeric matrices.
Moreover, with evolution, many latest and complex
arrangements of reinforcements have been introduced in the process with the
inclusion of additives and fillers. Thus, the size and complexity of the
pultruded cross-sections have evolved accordingly considerably which have been
used by the composite industry for a range of civil engineering and other
applications.
Why pultrusion process gets an extra edge with
Fibre-Reinforced Polymer (FRP)?
It is no wonder that using a quality raw material affects
the pultrusion process that is why the aviation and civil engineering industry
started looking at fibre-reinforced polymer (FRP) materials with a
resurgent interest which stemmed out of its offering of high durability,
satisfactory performance for higher construction speeds, and multifaceted
functionality.
By producing FRP materials which not only have high
mechanical performance but also lightweight, the pultrusion process has taken a
new high. Since FRP materials are less prone to the degradation that is caused
by the aggressive environmental agents and require minimum maintenance during
provided service life in comparison to traditional materials, the entire
composite industry looks up to this high-quality raw material.
With raw material like FRP, various types of fibre
reinforcement can be manufactured like continuous or unidirectional fibre
reinforcement, discontinuous or chopped fibre reinforcement, and woven or
bidirectional reinforcement, all of which offer a wide range of usability and
set of properties. For polymers that possess high specific wear rates,
reinforcing fibre results in significant reductions in wear and improvement in
mechanical properties, thus is preferably used in comparison to other raw
materials. Besides reinforcement, the fibre orientation viz. - normal,
parallel, cross and anti-parallel also affect the wear of composites.
Conclusion
SGS Frangible uses highest quality fiber in pultrusion
process for producing quality composites, it feels immense responsibility and
honor to constantly delivering the standards and consistency through its
authentic and quality products under minimum cost and high speed just like
pultrusion process.
So, next time when you see a Frangible Tower or mast at
an airport, do think on the technology involved during its manufacturing
process to provide a SAFE & STRONG structure.
