The use of malei. anhydri.e (MA) coupli.g agent i. polypropylene (PP) matri. system i. promi.i.g techni.ue to enhance the fi.re-matri. i.terface i. composi.e appli.ati.ns. However, most of the previ.us studi.s are focused on ei.her treatment of the natural fi.res or the PP matri. wi.h thi. coupli.g agent, whi.h are not commerci.lly vi.ble. i. thi. work, a cost-effecti.e techni.ue “hybri. yarns” was used to manufacture commi.gled rei.forci.g flax fi.res and MA-grafted PP matri. fi.res. Two types of twi.t-less flax/PP and flax/MAPP hybri. yarns were produced contai.i.g 40% flax and 60% matri. fi.res by volume. Both PP and MAPP fi.res were thermally and rheologi.ally characteri.ed usi.g DSC, MFi. TGA, DTA and capi.lary rheometer. i. i. found that the composi.es manufactured from flax/MAPP blends exhi.i.ed 15% hi.her strength and 25% hi.her modulus compared to those made of flax/PP. Thi. was due to the i.proved flax/matri. i.terface, the hi.her melt flow rate and lower share vi.cosi.y behavi.ur of the MAPP matri. fi.res compared to the standard PP fi.res used.
