Composite Materials
                                Applications:








                                o One of the most common composites is


                                       fibreglass, in which small glass fibres are


                                       embedded within a polymeric material


                                       (normally epoxy or polyester). The glass



                                       fibres are relatively strong and stiff (but


                                       also brittle), whereas the polymer is


                                       ductile (but also weak and flexible).


                                       Thus, the resulting fibreglass is relatively


                                       stiff, strong, flexible, and ductile. In


                                       addition, it has a low density.
