This document introduces continuous fiber thermoplastic composite materials as a new alternative to traditional materials like metals, thermoset composites, and injection molding. Thermoplastic composites combine continuous fiber reinforcement in a thermoplastic matrix, offering high strength, damage tolerance, and lightweight properties. The melt and compression molding process is faster than other composites and allows for creative part designs. Thermoplastic composites provide advantages over metals in strength, weight reduction, thermal properties, and corrosion resistance, while offering faster cycles and recyclability over thermoset composites.
Jute, an eco-friendly and affordable fiber grown profusely in India, possess unique combination of properties suited for the manufacture of non-textile products. However, its contribution for technical applications is limited at present. In this research, an effort has been made to investigate the physical and morphological properties of jute fiber when incorporated in epoxy matrix with a view to widen the share of jute fibers for engineered applications. Composite specimens containing nonwoven jute mat and alkali treated short jute fibers with different weight percentages (1, 2 wt%) were made using epoxy resin. The water absorption, thickness swelling (TS) and morphology [scanning electron microscopy (SEM)] tests of the bio composites were performed. As the fiber fraction ratio was increased the values for water absorption (WA) and thickness swell (TS) were found to be increased. The samples reinforced with 2 wt. percent fiber fractions showed maximum WA and TS in both water environments.

Fibre Reinforced Plastic manufacturing methodsjeff jose
Composites manufacturing processes are complex, and involve combinations of the following physical processes:
1) Reinforcement Shaping
2) Resin Infusion
3) Composite Consolidation
Advantages and disadvantages of processing techniques
plastic composite manufacturing
Hand Lay-up
Spray up method
Filament winding
Match die molding
Pultrusion
Resin transfer molding
Reaction injection molding
Hand Lay-Up is well suited for low volume production of product.
This method can be used for both corrosion barrier and the structural portion
Fiber is chopped in a hand-held gun and fed into a spray of catalyzed resin directed at the mold. The deposited materials are left to cure under standard atmospheric conditions.
Here the composite material was fabricated using sugarcane bagasse, jute fibre & with glass fibre as a hybrid material and the mechanical properties of this material was studied.

High performance polymer fibre reinforced metal matrix composites- Metal Orga...Padmanabhan Krishnan
Zylon reinforced aluminium, zinc and lead low melting metal matrix composites that broadly belong to the MOF ( Metal Organic Framework ) materials were processed, characterised and measured for their properties and foreseen applications.
Plastic injection molding continues to advance as new technology emerges, and with its growth comes new opportunities for using parts made with this method in automotive manufacturing. The global industry continues to work a higher percentage of plastic injection molding parts into each new round of vehicle designs, and plastic injection molding is capable of keeping up with demand.

2. New Solution To An Old Problem
• Many materials and processes have been such as thermoset matrix
composites, each requiring compromise in one or more key
characteristics.
• Traditional materials such as aluminum require extensive machining
steps, are not easily adapted to imaginative style, and they lack
damage tolerance.
• Steel is generally relegated to rectilinear design and is very heavy.
• Magnesium alloys require expensive tooling, considerable post
processing, lack damage tolerance, and are expensive.
• Injection molding processes offer lightweight fabrications with
considerable style in smaller components. Injection molded parts
are generally less damage tolerant, do not have good thermal
properties, and require expensive tooling. They are very competitive
in high volume small parts.
• A new alternative to all these is continuous fiber thermoplastic
composite materials made by Fibrtec.
3. Continuous Fiber Thermoplastic
Composites
• The continuous fiber in a thermoplastic matrix such as nylon
combines to make an extremely stiff, damage tolerant, lightweight
structural composite.
• A comparable part in machined aluminum would weigh 40% more.
This is a strong advantage for the composite.
• In addition to the high strength to weight ratio they also have very
good thermal conductivity and have extremely low coefficients of
thermal expansion. This simplifies tolerance issues for devices such
as optical benches that would be affected by movement of a cover.
It also simplifies many thermal management problems.
• EMI/EMC shielding is incorporated in the composite and provide
superior performance that does not erode or flake off with time.
Styling and ergonomic designs are very compatible with the
process; your designers are free to be creative in their designs.
4. Low Cost Fabrication
• The continuous fiber thermoplastic composites are made through a
melt and compression molding process.
• Contrasting with conventional thermoset composites which rely on
solvent based chemistry and complicated cure schedules.
• Many of these materials can be molded in low cost aluminum molds,
higher temperature materials require steel.
• The process is very fast for a composite, under 5 minutes a part for
many of the parts contemplated for this application.
5. Thermoplastic Composite Advantages
Compared to Metals:
• High Strength/Stiffness; Toughness
• Reduced Weight
• Low Coefficient of Thermal Expansion (CTE)
• Corrosion and Chemical Resistance
• Increased Part Function via Parts Consolidation
• Reduced Secondary Operations
• Styling Freedom/Contoured Shapes
Compared to Thermoset Composites:
• No Need For Controlled Storage/Unlimited Shelf Life
• Significantly Faster Cycle Times (lower mfg. cost)
• Environmentally Sound and Recyclable
• Can be re-processed – reduced scrap
• Superior Toughness
6. Winning Solution
• Consistency, rapid processing, and style
• Combined with high strength, light weight,
and thermal conductivity
• Make this material the best choice for high
performance structural parts.
