Reinforced-plastic fiber content

As is known of glass fiber-reinforced plastics, the mechanical and physical properties of composites, next to the fiber properties, and the quality of the fiber matrix interface, as well as the textile form of the reinforcement primarily depend on the volume content of fibers in the composite. 

Our study is outlined in five parts, (a) Two polystyrene plastics were reinforced at different fiber contents alternately with polyester, asbestos, and glass fibers, (b) The mechanical/physical properties of the resultant monofiber-reinforced plastics were determined and compared, (c) Combinations of fibers were then used to fabricate multifiber-rein-forced structures to exploit simultaneously the particular advantages of the different reinforcements, (d) The effect of each fabrication stage on the molecular weight and molecular weight distribution of the matrix plastics was established and (e) a linear mathematical model was formulated to predict the properties of multifiber structures and forecasted values compared with corresponding values experimentally obtained from (c) above. 

Based on contents of an RP other terms are used to identify an RP. Examples include glass fiber reinforced plastic (GFRP), aramid fiber reinforced plastic (AFRP), carbon fiber reinforced plastic (CFRP), graphite fiber reinforced plastic (GFRP), boron fiber reinforced plastic (BFRP), etc. 

How reqrclahle is the formulation In many cases, a compound simply may not be easily recyclable using the current material-recovery infrastructure, even for parts that are well labeled with the codes that identify their mineral or fiber content Fossil-fuel cost pressures and environmental pressures are only starting to provide the necessary impetus for the greater recovery of filled or reinforced plastic products when their lifetimes are complete Fortunately for POs, a basic recycling infrastructure already exists, and these materials comprise a family of plastics that is readily and heavily recycled into other products. This makes the filler/fiber content a less complicating factor for recovering POs from automotive shredder residue or consumer recydate... 

Cellulose nanofibers from different sources have showed remarkable characteristics as reinforcement material for optically transparent composites [160, 161], Iwamoto et al. [160] prepared optically transparent composites of transparent acrylic resin reinforced with cellulose nanofibers extracted from wood pulp fibers by fibrillation process. They showed that cellulose nanofiber-reinforced composites are able to retain the transparency of the matrix resin even at high fiber content (up to70 % wt). The aggregation of cellulose nanofibers also contributes to a significant improvement in the thermal expansion properties of plastics. 

These widely cited papers contribute to dimming the boundary between the polymer blend and polymer composite. Blends of thermofiopic LCPs with thermoplastic polymers are processed and molded by conventional techniques such as extrusion, injection molding, and spinning with related equipment. However, the resultant products have the characteristic reinforced structure and mechanical behaviors of fiber-reinforced plastics or composites. It is common where technical terms of LCP blends and in situ composites have the same meaning. LCP blends almost refer to blends with thermofiopic LCPs as the minor portion so that in sim composites and newly invented in situ hybrid composites are the main content of this chapter on polymer blends.
