Phenolic resin filled

Mechanical Properties and Fracture Behavior. Until recently, little was known about the sequence of fracture behavior that occurs in the 2D composites that are used to fabricate large C-C structures, such as the exit cones of rocket engines. In such composites, the yarns in the cloth are held together by a carbon matrix derived from a phenolic resin filled with carbon particles. [Pg.396]

Typical systems are polyester and phenolic resins filled with glass fibres and mineral fillers. [Pg.396]

Wu et al.3 compared the friction and wear properties of phenolic resin-filled calcium carbonate whiskers and potassium titanate whiskers. They found that calcium carbonate whisker-filled friction material shows the lowest sensitivity to speed and easy to cause surface abrasion whereas potassium titanate whiskers-filled friction material shows the lowest sensitivity to load and the highest sensitivity to speed. [Pg.236]

Molding applications dominate the market of phenolic resins. Articles produced by injection molding have outstanding heat resistance and dimensional stability. Compression-molded glass-filled phenolic disk brake pistons are replacing the steel ones in many automobiles because of their light weight and corrosion resistance. [Pg.348]

The quantity of resin applied to the reinforcing ply to achieve a state of full densification varies inversely with the laminating pressure. Therefore, high pressure laminates pressed at about 7 MPa (1000 psi) need only about 25—30% phenolic resin in kraft paper, whereas low pressure (1 MPa = 145 psi) laminates need 50—60% resin in the reinforcing ply if all voids are to be filled in the final product. [Pg.534]

Syntactic foamed plastics (from the Greek ovvxa C, to put together) or spheroplastics are a special kind of gas filled polymeric material. They consist of a polymer matrix, called the binder, and a filler of hollow spherical particles, called microspheres, microcapsules, or microballoons, distributed within the binder. Expoxy and phenolic resins, polyesters, silicones, polyurethanes, and several other polymers and oligomers are used as binders, while the fillers have been made of glass, carbon, metal, ceramics, polymers, and resins. The foamed plastic is formed by the microcapsular method, i.e. the gas-filled particles are inserted into the polymer binder1,2). [Pg.67]

The methods used to increase the water resistance of a glass microsphere foam are basically those applied to glass-reinforced plastics, filled thermoplasts, and elastomers, viz. hydrophobic adhesion compounds are added to binder and microsphere dressing 147). The compounds added are alkyl alkoxysilane derivatives, amino or epoxy alkoxysilanes for epoxy and phenolic resins, vinyl or methacryloxy alkoxysilanes for polyester resins. The dressing agents used are aminoethoxysilanes (y-aminopropyl-... [Pg.98]

Fire resistance is an important property of phenolic resins. The combination of phenolic resin with Expancel expandable microspheres leads to many useful products. Composites for high speed train interiors take advantage of the light weight, excellent fire rating, and very low thermal conductivity. Polyester filled with aluminum hydroxide is an alternative solution for train interior materials. The resin and filler can be easily processed when viscosity regulating additives are added. [Pg.625]

A large diffusion may be found also for composite materials, carbon, or metal based. In the first case different types of polymeric resins (thermoplastics, such as polypropylene, polyethylene, and PVDF, or thermosettings, such as epoxies and phenolics) are filled with carbonaceous powders (graphite or carbon blacks), to provide a material characterized by very high chemical stability in the fuel cell environment and satisfactory properties of electrical conductivity, but which cannot offer sufficient robustness at thickness lower than 2 mm. The metal composite plates are essentially based on combinations (sandwiches of different layers) of stainless steel, porous graphite, and polycarbonates, with the aim to exploit the characteristics of different materials. Their fabrication can be more complex but this is compensated by the possibility to incorporate other functional components, such as manifolds, seals, and cooling layers. [Pg.88]

Peng and Riedl (1994) investigated the chemorheology of phenol formaldehyde resins filled with unmodified and methylolated lignin fillers. They found that both fillers reduced the reaction rate and that the chemorheology profile of filled systems is better represented by the WLF model than by the Arrenhius model. [Pg.362]

Lignin is a phenol propane-based amorphous solidified resin, filling the spaces between the polysaccharide fibers. Lignin is not just a concrete but also a highly engineered chemical structure (Fig. 3.2). [Pg.92]
