Palmyra And Polyester Essay

Palmyra / Glass / Polyester composite. The similar results are observed for Sisal / Glass / Polypropylene [20], Roselle / Sisal / polyester [14], Banana / sisal / polyester [25], Jute roving / polyester [26], Hemp / Glass / Epoxy[27] composite. From table 7 show that PPLSF / Glass / Polyester [16], PPLSF/Jute/ Polyester [23] composite have higher flexural strength 173 Mpa, 164 Mpa respectively. This hybrid composite 30 wt%, 55 wt% fibers. In case of reason flexural strength improved. From the above observation PPLSF/CF – polyester composite have superior properties and potential reinforcement for manufacturing composite.

The maximum impact strength obtained P75C25 hybrid composite. which is 73% higher than neat resin. The impact strength of the composite P50C50, P25C75 have 30 KJ/m2, 24 KJ/m2. The impact strength of the composite decreased due to improvement of the fiber content. The impact strength of various natural fiber hybrid composite resulted are shown in table 8. Palmyra / glass/ polyester have 60 KJ/m2 . It is 50% higher than PPLSF/CRF- polyester composite. The same result has observed Palmyra /glass/ Polyester[17], Curuva / Glass / Polyester[16], Coir / Jute / polyester[23] composite. Finally a negative hybrid effect obtained in impact
