Long glass fiber-reinforced

As an example LNP Engineering Plastics, USA has been publishing results of tests that include a selection of die-cast metals compared with a 60 wt% long glass fiber reinforced nylon 6/6 compound (Verton RF700-12EM). The conclusion was that (for moisture-conditioned samples) with a density lower than metals, with the exception of certain... 

Fillers and reinforcing fibers 7 and 8 Engineering-type applications for POs (especially PP and TPO), more interest in sustainable fillers and fibers Greater use of cellulose-based fiber reinforcements, of long-glass fiber reinforcement, and of nanofillers and specially fillers... 

The nature of the process influences warpage. CM, for instance, produces moldings with homogeneous mechanical properties (little anisotropy) and minimum warpage, even in long glass fiber-reinforced parts (short flow paths, low fiber damage levels due to low shear rates). 

In motor vehicles, long glass fiber-reinforced parts with a matrix consisting of unsaturated polyester resin (SMC/sheet molding compounds) are used for example in front-ends, radiator grills, or bumper (frames). After utilization, they are discarded as waste by workshops or as part of the plastic and composite material share in used vehicles.

Another interesting long glass fiber-reinforced thermoplastic BMC operation was developed by Composite Products, Inc. (219,220). Basically it is an on-site extrusion and molding operation. The long glass fibers, up to 50 mm long, are fed downstream into the extruder. The compound exits the open die as a log and is stationed in the accumulator until compression molded. Thermoplastic SMC process has been recently patented by ThermoComp (221).
