The evolution of composite materials is an interesting one; it is ever changing and found in all industries on all scales. Some aircraft of composite materials began to appear in the late 1930s and ’40s; normally these were plastic-impregnated wood materials, the most famous (and largest) example of which is the Duramold construction of the eight-engine Hughes flying boat. Found insideComposite structures are massively exploited in many engineering fields. For instance, the state-of-the-art civil aircraft (B787 and A350) are mostly made of composite materials. Composite materials are created by combining two or more constituent materials with matrix materials to create a stronger and higher quality composite more suited to the required application. Many materials are capable of reinforcing polymers. The properties acquired by the composite material can be used for different reasons. Tube and rod preparation involves trimming the ends of tubes and removing the rich resin outer surface. In Automotive, composites are used throughout the cars. Entire homes can be framed using plastic-laminated beams and trusses instead of traditional wood framing. Uses: The Tufcot® T100 MP is commonly used in rudder and pintle bushes in the Marine environment, it can be water, oil or grease lubricated and equally efficient in dry running conditions. This separation of materials is what defines the finished product as a composite rather than a mixture or solution. The high compression strength, sliding ability and wear resistance of our wear rings and bearings guarantee a long-life span with minimal need for parts replacements and maintenance.

Once a composite has been designed it can be remade to exacting specifications and adapted for ongoing improvements where necessary. The structure of many composites (such as those used in the wing and body panels of aircraft), consists of a honeycomb of plastic sandwiched between two skins of carbon-fibre reinforced composite material. Composites are often chosen for their strength. It is obligatory that a composite structural designer should have a thorough knowledge about the process and development of composite materials and their characteristic behaviour. %%EOF Composites are generally made of two main materials (though theremay be other additives as well): there's a "background" materialcalled a matrix (or matrix phase) and, to this, we add a transformingmaterial called the reinforcement(or reinforcing phase). Our philosophy is to constantly invest in research and development projects. Risk of delamination – where two or more materials are connected, there is risk of delamination due to potential air pockets and insufficient compression or temperature. They are also commonly used in mobile and offshore hydraulics.
