Filler can have a negative or positive effect on fatigue resistance depending on the filler type and shape. In general fillers create small discontinuities in the matrix. This can contribute to crack initiation point. If the filler is brittle fatigue resistance will be low, whereas if the filler is very ductile the composite will be fatigue ...
Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. [1] The sheet is provided in rolls weighing up to 1000 kg. Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and ...
Bulk moulding compound (BMC), bulk moulding composite, or dough moulding compound (DMC), [1] is a ready-to-mold, glass-fiber reinforced thermoset polymer material primarily used in compression moulding, as well as in injection moulding and transfer moulding. [1]
A grain filler (pore filler or paste wood filler) is a woodworking product that is used to achieve a smooth-textured wood finish by filling pores in the wood grain. It is used particularly on open grained woods such as oak , mahogany and walnut where building up multiple layers of standard wood finish is ineffective or impractical.
These include some gas welding processes such as lead burning (although fillers may optionally be used) and oxy-acetylene welding in some positions, such as seam welding the edges of two overlapping sheets. Resistance welding, both spot welding and seam welding, is inherently autogenous, as there is no convenient way to apply a filler.
Pore fillers used for large flat surfaces such as floors or table tops generally contain silica instead of or in addition to wood dust. Pores can also be filled using multiple coats of the final finish rather than a pore filler. [1] [2] The main problem in using putty is matching the colour of the putty to that of the wood.
There are several types of fillers used by the packaging industry. The following are the most common: Auger/agitator fillers: designed to fill dry mixes, such as flour and sugar. [1] The fillers have a hopper shaped like a cone that holds the mix and puts it in a pouch using an auger conveyor that is controlled by the agitator. The mix is ...
