A Composite from Multidirectional Laminates

                         

                   Figure: A Composite from Multidirectional Laminates

Glass fibres usually used along with polyester as matrix can improve unidirectional tensile strength in between 200 to 350 MPa along with modulus of elasticity in between 100 to 300 MPa. Generally higher weight percent of glass fibres construct the composite stronger. That high as 80% fibre glass content is utilized in various case. Equal strength in each direction is acquired if chopped rovings are employed as reinforcing material. But strength in this term is less than that throughout directional strands. Glass woven cloth sheets are utilized as reinforcer also in plastic but fibres lose strength at interlacing points because of interference. Boat hulls, building and structure panels are made in glass fibre reinforced polyester.
