However, CFRP have been pointed out because of machining problems such as delamination and burr phenomenons. Especially, hole machining process, drilling, has non-smooth features on inlet and outlet surfaces of drilled hole. This kind of machining problem can be controlled to some extent by using high modulus pitch- CF, which has considerable effects on fracture behavior of composite compared with only PAN CF composite. Therefore, PAN and pitch hybridized CF composites were prepared having high strength and modulus. The results demonstrate that the hybrid CFRP specimens with pitch CF offer the good potential to enhance modulus as well as strength properties. Dynamic mechanical, flexural, and impact properties were measured and analyzed. Morphological surface of the composites were also observed by IFS-28, canon after hole machining. Keywords Keywords CFRP, pitch CF, fracture behavior, high modulus, PAN/Pitch CF composites 313 연구논문(학술) Download   Reference http://www.koreascience.or.kr/article/ArticleFullRecord.jsp?cn=OSGGBT_2018_v30n4_313&ordernum=
