Carbon eriri nwere elu kpọmkwem ike, elu kpọmkwem modulus, ike ọgwụgwụ na-eguzogide, corrosion iguzogide na ndị ọzọ magburu onwe Njirimara, ọtụtụ ebe aerospace, agha ụlọ ọrụ, egwuregwu akụrụngwa na ndị ọzọ ubi. Njirimara igwe nke eriri carbon gbanyere ihe mejupụtara matriks polymer siri ike dabere na njirimara interface dị n'etiti eriri carbon na matriks. Agbanyeghị, ihu igwe dị mma nke eriri carbon, ihe mmetụta mmetụta dị elu na otu ndị na-arụ ọrụ kemịkalụ ole na ole na-ebute njikọ njikọ na-adịghị ike n'etiti eriri carbon na resin matrix, na usoro interface na-abụkarị njikọ na-adịghị ike nke ihe mejupụtara. Ihe dị n'etiti microstructure nke carbon fiber composites nwere njikọ chiri anya na njirimara interfacial. Ọdịiche dị n'elu nke eriri carbon na-adabere na ọdịdị elu nke eriri carbon yana ụdị nke otu ndị na-arụ ọrụ kemịkal. Ma mmụba nke otu ndị na-arụ ọrụ na mmụba nke ịdị nro nke elu carbon fiber na-eme ka mmụba nke ikuku carbon fiber na-abawanye ike. Njirimara anụ ahụ dị n'elu nke eriri carbon na-agụnye morphology elu, nha na nkesa elu, ịdị njọ nke elu, ike enweghị n'elu na ihe ndị ọzọ. N'ihe gbasara ọdịdị ọdịdị elu, e nwere ọtụtụ pores, grooves, adịghị ọcha na kristal n'elu eriri carbon, nke nwere mmetụta dị ukwuu na njikọ njikọ nke ihe ndị mejupụtara. The chemical reactivity nke carbon fiber elu nwere njikọ chiri anya na ịta nke nọ n'ọrụ dị iche iche, na ndị a na-arụ ọrụ otu bụ tumadi oxygen nwere ọrụ otu dị ka ìhè otu, spindle otu na epoxy otu. Ọnụọgụ nke otu ndị na-arụ ọrụ n'elu eriri carbon dabere na usoro ọgwụgwọ electrochemical nke elu yana ogo ma ọ bụ okpomọkụ nke carbonization fiber.
