Fiber reinforcement molding

Foelster, T., Greiner, R., Schaefer, D. (2001). Fiber-reinforced molded plastic part and process for its manufacture. United States Patent 6184272. [Pg.442]

The last part of the book covers the various aspects of RIM technology, such as mold release, glass-fiber reinforcement, mold filling, and new developments in RIM equipment. [Pg.2]

Preform v. (1) To make plastic molding powders into pellets, tablets, or biscuits of known mass that facilitate accuracy in compression molding. (2) To prepare by hand cutting of reinforcing cloth or mat, or by blowing chopped fibers onto a contoured screen, the reinforcement for a fiber-reinforced molded object. The reinforcement, which has a shape close to that of the final molded object, is placed into or onto the mold along with the required amount of resin, then wet out and cured. [Pg.784]

In thermoplastics, carbon fiber compounds have been developed with nylon, polysulfone, thermoplastic, polyester, polyphenylene sulfide, polycarbonate, polypropylene, polyamide-imide, and ethylene/tetrafluoroethylene copolymer. Carbon fiber-reinforced molding compounds are available with carbon fiber contents of various levels such as 20, 30, and 40 weight percent. Nylon 66 molding compounds have also been developed with hybrid combinations of carbon and glass fiber reinforcements. [Pg.240]

An important application for rubber modified polyester resins is in short-fiber reinforced molding compounds. Specific applications within the automotive industry include grill-opening panels and various car and truck body panels. Rubber modified vinyl ester resins are used as adhesives and as primer coatings for storage tanks. [Pg.425]

Pure UP or VE resins exhibit notably better resistance than corresponding glass fiber reinforced composites. This fact has led to the introduction of resinous surface coatings for all glass fiber-reinforced molded parts under medial loads - so-called gel coats. With the intensive utilization of UP and VE resins in corrosive environments, the composition of the protective coating as a chemical protective layer for the structure laminate is described in DIN 18820 [8] part 3. [Pg.410]

UP/PHA resin suitability for glass fiber-reinforced molded parts that are exposed to corrosive media and environmental influences has contributed greatly to their wider application. On the basis of economic and technical factors, laminates based on unsaturated polyester resins and vinyl ester resins have become an indispensable, alternative material in industries with high corrosive loads, such as cellulose and paper [876], chlorine electrolysis [877], flue gas desulphurization in power plants and waste incineration plants, [878] and as pipelines for communal and industrial waste water [879].

This variety of polymeric building blocks can be used to tailor the properties of a polymer to the specific areas of application. They can be used for adhesives, coatings, molded goods and reinforced plastics. If the latter are made with natural fibers e.g. - flax, - hemp and - sisal as reinforcement, almost totally RR-based products are accessible (- fiber reinforced molded goods). All these products have the benefit of being based on renewable resources they are biodegradable, can be recycled and have an unlimited availabilty. [Pg.230]
