Por meio de m\u00e9todos f\u00edsicos ou qu\u00edmicos, eles formam materiais com novas propriedades em n\u00edvel macro (micro). Esses materiais componentes mant\u00eam sua independ\u00eancia relativa no composto. E trabalham em coopera\u00e7\u00e3o uns com os outros para conferir ao composto propriedades que um \u00fanico material n\u00e3o pode ter. Por exemplo, pl\u00e1sticos refor\u00e7ados com fibra de vidro. A fibra de vidro proporciona alta resist\u00eancia e rigidez, enquanto o pl\u00e1stico d\u00e1 ao material boa conformabilidade e resist\u00eancia qu\u00edmica. E eles se combinam para criar um material composto com excelente desempenho.<\/p>\n<p class=\"ql-align-justify\"><strong>Principais caracter\u00edsticas<\/strong><\/p>\n<p class=\"ql-align-justify\">Em primeiro lugar, o material composto \u00e9 projet\u00e1vel.

Assim, \u00e9 poss\u00edvel controlar com precis\u00e3o o desempenho dos materiais compostos. Em segundo lugar, os compostos tendem a ter um desempenho melhor do que as simples sobreposi\u00e7\u00f5es de seus materiais constituintes, o que \u00e9 chamado de \"sinergia\". Al\u00e9m disso, h\u00e1 uma interface \u00f3bvia entre os componentes do material composto.
