A BN particle and aluminosilicate short fibre reinforced hybrid Al-12Si composite was fabricated by squeeze casting. The interface microstructures between reinforcements and matrix were investigated by transmission electron microscopy (TEM). The experimental results showed that there is no reaction product formation at fibre/matrix and BN/matrix interface, and the matrix is in intimate contact with fibre and BN. Because of the addition of self-lubricant BN particles and good connection between BN and matrix alloy, the coefficient of friction of the hybrid composite is improved.
