Pseudo-first-order pseudo-second-order equations were to study kinetic data. A Langmuir isotherm model investigate equilibrium experimental monolayer...

The use of natural fibers in composite is rising recent years due their lightweight, non-abrasive, combustible, non-toxic, low cost and biodegradable properties. However, comparison with synthetic fibers, the mechanical properties are lower. Therefore, inclusion could improve performance fiber based composites. In this study, kenaf bast glass at different weight percentage loading were used as reinforcement to produce hybrid Unsaturated polyester (UP) resin was matrix hand lay-up process...

Kenaf and glass fiber hybrid composite was prepared by using hand lay-up process. The effect of weather on mechanical properties kenaf/glass composites studied. samples were exposed to natural weather. Tensile test performed for at different weathering exposure time. strength 70.9 MPa tensile modulus 30 GPa before expose environment Unfortunately, decreased as time increase due the moisture absorption which further promotes weakness in interfacial bonding.

Hybrid composites were prepared using kenaf fiber and glass at different percentage loading as reinforcement. Unsaturated polyester (UPE) resin was used a binder hand lay-up method performed to apply the on kenaf/glass hybrid composite. Effect of flexural strength, modulus impact strength composite studied. It found that increases with increasing content up 20 weight percent kenaf/10 fiber. Optimum achieved
