Composite Materials / Bahan Komposit

1 (a) Composite materials are structural materials that are formed by combining two or more different substances such as
metal , alloys , ceramic , glass and polymer .
Bahan-bahan komposit adalah bahan yang diperbuat daripada gabungan dua atau lebih bahan berbeza seperti logam ,
aloi , seramik , kaca dan polimer .
(b) Composite materials have properties that are superior than those of the original components.
Bahan-bahan komposit mempunyai sifat-sifat yang lebih baik berbanding dengan komponen-komponen asal.
