Abstract:

Carbon fibre reinforced plastics (CFRPs) can be classified according to whether the matrix is a thermoset or a thermoplastic. Thermoset-matrix composites are by tradition far more common, but thermoplastic-matrix composites are gaining in importance. There are several techniques for combining carbon fibres with a thermoplastic-matrix system. The composite’s characteristics as well as its manufacturing costs are dependent on the impregnation technique of the carbon fibre and the textile structure respectively. Carbon fibre reinforced thermoplastics (CFRTPs) are suitable for fast and economic pr

Abstract:

The combination of fibre-reinforced materials with metals is defined as a fibre metal laminate. These material composites have already been a subject of research for several years. The long manufacturing time resulting from the period required for consolidation of the thermosetting resin is a major disadvantage of the fibre metal laminates previously in use (for instance GLARE, which is a combination of aluminium with glass fibre-reinforced plastic). In this paper, a new fibre metal laminate with a thermoplastic resin in the carbon fibre-reinforced plastics (CFRP) is introduced. The applicatio

Abstract:

Nowadays, orthoses are made from fibre reinforced thermoset based composites with a high manual labor input. These thermoset based orthoses are no longer formable, which brings forth a significant disadvantage. Hence, hybrid laminates consisting of fibre reinforced thermoplastic films and thin metal sheets can replace successive thermoset based systems due to their advantages of higher formability and the suitability for mass production. In the present work, various surface treatment methods like pickling or mechanical blasting have been used on thin metal sheets to increase the adhesive and s

This system is used in an integrated way with the filamentary fusion additive manufacturing technology and allows a localized and oriented reinforcement of polymer components for advanced engineering applications at a low cost. To demonstrate the capabilities of the developed system, composite components of thermoplastic matrix (polyamide) reinforced with pre-impregnated long carbon fiber (carbon + polyamide), 1 K and 3 K, were proc

Abstract:

Basalt fibres are inorganic man-made fibres which, in fibre-reinforced plastic composites (FRP), represent a cost-effective alternative to carbon fibres. Within petrochemical thermoplastic matrices, basalt fibres are established in technical applications. The use of biobased polyamides as matrix material is an innovative approach for the production of FRP with a high proportion of renewable raw materials. In addition to material selection, the compound manufacturing process also defines the properties of the FRP. At the Institute of Lightweight Structures, extensive investigations are carried

Abstract:

To date, nonwoven fabrics made with natural fibres and thermoplastic commingled fibres have been extensively used in the composite industry for a wide variety of applications. This paper presents an innovative study about the effect of the manufacturing parameters on the mechanical behaviour of flax/PP nonwoven reinforced composites. The mechanical properties of nonwoven fabric reinforced composites are related directly to the ones of dry nonwoven reinforcements, which depend strongly on the nonwoven manufacturing parameters, such as the needle-punching and areal densities. Consequently, the i

ABSTRACTWe demonstrate that Additive Manufacturing (3D printing) is a viable approach to rapidly prototype personalised fins for surfboards. Surfing is an iconic sport that is extremely popular in coastal regions around the world. We use computer aided design and 3D printing of a wide range of composite materials to print fins for surfboards, e.g. ABS, carbon fibre, fibre glass and amorphous thermoplastic poly(etherimide) resins. The mechanical characteristics of our 3D printed fins were found to be comparable to commercial fins. Computational fluid dynamics was employed to calculate longitudi

Carbon fibre-reinforced polymer (CFRP) composites are used in various engineering fields with their excellent mechanical properties and lightweight. However, thermoset epoxy composites with brittle epoxy resin system are leading low fracture toughness that caused deterioration during cyclic loading. In addition, the delamination occurred on the thermoset laminated composite material to impact. In this study, to improve these problems, thermoplastic resin added on the top and bottom of thermoset composites and to impregnate two resins that are not compatible on reinforcement, combined prepregs

Abstract:

Purpose Fused filament fabrication (FFF) is one of the most popular additive manufacturing (AM) technologies due to its ability to build thermoplastic parts with complex geometries at low cost. The FFF technique has been mainly used for rapid prototyping owing to the poor mechanical and geometrical properties of pure thermoplastic parts. However, both the development of new fibre-reinforced filaments with improved mechanical properties, and more accurate composite 3D printers have broadened the scope of FFF applications to functional components. FFF is a complex process with a large number of

Overmoulding of thermoplastic composites combines the steps of thermoforming and injection moulding in an integrated manufacturing process. The combination of continuous fibre-reinforced thermoplastics with overmoulded polymer enables the manufacturing of highly functionally integrated structures with excellent mechanical properties. When performed as a one-shot process, an economically efficient manufacturing of geometrical complex lightweight parts within short cycle times is possible. However, a major challenge in the part and process design of overmoulded thermoplastic composites (OTC) is

Abstract:

Fibre-reinforced thermoplastic composite materials can be manufactured rapidly using a thermoforming process. The assortment of thermoplastic matrix systems is manifold and starts from bulk plastic like polypropylene (PP) up to high-performance systems like polyether ether ketone. High-performance thermoplastic polymers have durable properties but relatively high raw material costs. For structural application, engineering methods are needed to ensure the availability for use over the full range of the life cycle of parts. This equates to at least 15 years under exposure to varying climatic con

Furthermore, a consolidation of cross-section varying parts requires an adapted mold and core system for a reproducible production process. Similarly, the application of hybrid yarns facilitates low consolidation pressures and thus favors the integration of electronic components in fibre-reinforced thermoplastic parts.
