Bi-layer hybrid biocomposites were fabricated by hand lay-up technique by reinforcing oil palm empty fruit bunch (EFB) and jute fibre mats with epoxy matrix. Hybrid composites were prepared by varying the relative weight fraction of the two fibres. The physical (void content, density, dimensional stability), and chemical resistant properties of hybrid composites were evaluated. When the jute fi...

this work investigates the feasibility of using recycled high density polyethylene (rhdpe), recycled polypropylene (rpp) and old newsprint fiber (onp) to manufacture fiber reinforced composites. the boards were made through air-forming and hot press. the effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

Graphite epoxy composites lack effective mechanisms for absorbing local impact energy often resulting in penetration and a structural strength reduction. The effect of adding small amounts of two types of high strain hybrid components on the impact resistance of graphite epoxy composites subjected to projectiles traveling at ballistic velocities (greater than 900 ft/sec) has been studied. The h...

To modify water absorption properties of bamboo fiber (BF) and high density polyethylene (HDPE) composites, heat treatment of BFs was performed prior to compounding them with HDPE to form the composites. The moisture sorption property of the composites was measured and their diffusion coefficients (Dm) were evaluated using a one-dimensional diffusion model. Moisture diffusion coefficient values...

This paper discusses the potential use of multi-walled carbon nanotubes (MWCNTs) to improve the mechanical properties of short glass fiber composites. Two methods to incorporate MWCNTs in short glass fiber composite fabrication were examined. First, Carboxylic-functionalized MWCNTs were dispersed in a silane fiber sizing material and then were allowed to bond to the surface of glass fibers. Sec...

In this study, an attempt is made to check whether a hybrid composite up of both synthetic and natural fibers (Carbon Cordia Dichotoma respectively) can be bio-degradable, at least some extent, without much compromising on the mechanical properties. Hybrid composites were prepared by reinforcing alkali treated dichotoma carbon into epoxy resin using hand lay-up method. By varying number layers ...
