Description
Two kinds of phenol-ovolac based benzoxazine having different molecular weights weresynthesized. Glass fiber reinforced plastic (GFRP) was prepared using the molten mixture fromthe above benzoxazines and bisoxazoline as a matrix, and the effect of molecular weight ofbenzoxazines on the properties of GFRP was investigated. As a result, GFRP from the benzoxazinehaving largermolecular weight as a matrix showed higher heat resistance because of highercrosslink density. And GFRP from the benzoxazine having lower molecular weight as a matrix showed higher tensile, flexural and especially impact strength. The reason was considered as follows: in the case of the benzoxazine having lower molecular weight as a matrix, matrix wasso flexible due to lower crosslink density, and interfacial bonding strength between matrix and fiber was so low that stress concentration in matrix was easy to relax.
