An audio multicore cable and accompanying stage box. Multicore cables can be used for analog and digital signals as well as power distribution. They are often used to simplify the physical setup of a system and provide a neater connection between two pieces of equipment. [9]
Inserts are pins, bolts, screws, joints and other structures that are used to transfer localized loads to a composite panel or to join two composite panels together. Metallic inserts are commonly used in the aerospace and marine industries to attach objects to sandwich composite panels.
The thicker the core material the stronger the composite. This principle works in much the same way as an I-beam does. [6] The interface between the core and the skin: Because the shear stresses in the composite material change rapidly between the core and the skin, the adhesive layer also sees some degree of shear force. If the adhesive bond ...
Suppliers of advanced composite materials tend to be larger companies capable of doing the research and development necessary to provide the high-performance resin systems used in this segment of the industry. End-users also tend to be large, and many are in the aircraft and aerospace businesses. [1] [2] [3]
Components were attached to the chassis, usually by insulators when the connecting point on the chassis was metal, and then their leads were connected directly or with jumper wires by soldering, or sometimes using crimp connectors, wire connector lugs on screw terminals, or other methods. Circuits were large, bulky, heavy, and relatively ...
Polyurethanes are another group of resins used in advanced composite processes. These compounds are formed by reacting the polyol component with an isocyanate compound, typically toluene diisocyanate (TDI); methylene diisocyanate (MDI) and hexamethylene diisocyanate (HDI) are also widely used. Phenolic and amino resins are another group of PMC ...
The theory of sandwich panels and functions of the individual components may be described by making an analogy to an I-beam. The core in a sandwich panel is comparable to the web of an I-beam, which supports the flanges and allows them to act as a unit. The web of the I-beam and the core of the sandwich panels carry the beam shear stresses.
The composite structures of interest are mainly components composed of laminated plies or sandwich structures as shown in Figure 1. Laminate structures are assembled so that the fibre orientation provides most of the desired mechanical properties and the matrix largely determines the environmental performance.
