Glass reinforced thermosets

Reactive surface treatment assumes chemical reaction of the coupling agent with both of the components. The considerable success of silanes in glass reinforced thermosets have led to their application in other fields they are used, or at least experimented with, in all kinds of composites irrespective of the type, chemical composition or other characteristics of the components. Reactive treatment, however, is even more complicated than non-reactive polymerization of the coupling agent, development of chemically bonded and physisorbed layers render the identification of surface chemistry, characterization of the interlayer...

This particular ASTM procedure is not directly relevant to wood-thermoplastic composites, and therefore it is only briefly described here. The procedure is recommended for the determination of the tensile properties of thermosetting reinforced plastics. Experience with this test method has been limited to glass-reinforced thermosets. The principal difference with ASTM D 638, using dogbone-shaped specimen, is that ASTM D 5083 uses test specimens of uniform nominal width. [Pg.323]

Small amounts of TAIC together with DAP have been used to cure unsaturated polyesters in glass-reinforced thermosets (131). It has been used with polyfunctional methacrylate esters in anaerobic adhesives (132). TAIC and vinyl acetate are copolymetized in aqueous suspension, and vinyl alcohol copolymer gels are made from the products (133). Electron cure of poly(ethylene terephthalate) moldings containing TAIC improves heat resistance and transparency (134). [Pg.88]

Certain polymers are used largely, if not exclusively, for corrosion control purposes. The significant markets for corrosion control by polymers are composites (primarily glass-reinforced thermosetting resins) PVC pipe, polyethylene pipe, and fluoropolymers. [Pg.219]

The study concluded that the hybrid (hemp/glass)-reinforced thermoset was more eco-efficient than the conventional glass fibre alternative. The main advantage of the hybrid material was the reduction of glass fibre and resin content compared to standard... [Pg.312]
