In this paper, the tensile performance of 3D printed continuous fiber reinforced thermoplastic materials is investigated. Continuous carbon fiber and Polyethylene terephthalate glycol (PetG) are employed as reinforcement and matrix, respectively. Pure solid plastic infill, unidirectional fiber infill, and +45/-45 fiber infill patterns specimens are selected for printing and testing.

The performance of carbon fiber (CF)ereinforced thermoplastic composites is influenced by the interfacial adhesion strength of the fiber and thermoplastic matrix. In this study, the electrophoretic coating of silane-grafted polyphenylene sulfide (PPS) particles on the CF surface was used to quantitatively control the interfacial adhesion between the CF and PPS matrix.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. Additively manufactured TPU mould is developed to cast complex concrete structures. A planar topologically optimized cantilever and a free-form 3D column are cast using the proposed TPU mould. Good surface quality is obtained for the cast concrete elements, and the moulds can be reused many times after cleaning.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. The findings of this thesis will provide clear guidelines for the selection of processing parameters for additively manufactured TPU parts and the method of casting complicated concrete structures with additively manufactured TPU mould.

This mini-review article briefly introduces and classifies main types of bioplastic materials. The understanding of biobased content as well as biodegradability is also addressed. Lastly, three main classes of bio-based, biodegradable plastics which are thermoplastic starch (TPS), polylactic acid (PLA) and polyhydroxyalkanoate (PHA), are reviewed in terms of structure, properties, processing and applications.

Long fibre reinforced polymer composite materials have found many applications in many industries, such as aerospace, automotive, marine, wind turbine, and sports. Techniques for the manufacturing of structures used in these industries have been mainly Hand Lay Up (HLU), and Liquid Composite Moulding. While there are a few automated methods of manufacturing, such as Filament Winding and Pultrusion, these techniques are restricted to make structures that consist of surfaces of revolution, or fibres that are aligned only along one direction.

In the last 30 years, plastics have become the most dominant engineering material for most products. We take a brief look at the most common types of plastics, and how they are processed. All plastics are polymers, these polymers are further divided into two basic types: thermoplastics and thermosets.

In the additive RP processes, photopolymer systems are based on suc- cessively depositing thin layers of a liquid resin, which are then solidi- fied by exposure to a specific wavelengths of light. Thermoplastic sys- tems are based on procedures for successively melting and fusing solid filaments or beads of wax or plastic in layers, which harden in the air to form the finished object. Some systems form layers by applying adhe- sives or binders to materials such as paper, plastic powder, or coated ceramic beads to bond them.

Legibility and focus upon the content was a primary design consideration, as it is hoped the timeline will grow through a wealth of contributions. Early research to incorporate imagery into the timeline revealed the hurdle of copyrighted material on the World Wide Web, and the entanglement of Academic Fair Use, images in the public domain, partially copyrighted material, and 100% copyrighted material.

The most popular of the rigid reinforcements for printed wiring boards is woven E-glass (electrical-grade glass) fabric. These fabrics are constructed to meet weight, thickness, strength, and cost objectives. The woven fabric is used in many industries as reinforcements for thermoplastic and thermosetting plastic parts. Thermosetting laminates are particularly enhanced by the properties of the glass fabric.
