2. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   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 ...

3. Carbon-fiber reinforced polymer - Wikipedia

   en.wikipedia.org/wiki/Carbon-fiber_reinforced...

   Controversially, in 2006, cricket bats with a thin carbon-fiber layer on the back were introduced and used in competitive matches by high-profile players including Ricky Ponting and Michael Hussey. The carbon fiber was claimed to merely increase the durability of the bats, but it was banned from all first-class matches by the ICC in 2007. [37]

4. Bulk moulding compound - Wikipedia

   en.wikipedia.org/wiki/Bulk_moulding_compound

   The mixing is done at room temperature and stored at low temperatures to slow down curing prior to molding. The concentration of the mixture can vary depending on application, but is typically 30% glass fibers, 25% filler, and 45% resin, styrene, and initiator. [2] The material is provided in bulk or in logs approximately 4" in diameter.

   Bondo is a polyester putty product originally marketed as an automotive body filler. Nowadays the brand name is used by 3M for a line of American-made products for automotive, marine and household repairs.

7. Shape-memory polymer - Wikipedia

   en.wikipedia.org/wiki/Shape-memory_polymer

   [43] [44] Shape memory polymers have already been made into shape memory film by extruder machine, with covert and overt 3D embossed pattern internally, and 3D pattern will be released to be embossed or disappeared in just seconds irreversibly as soon as it is heated; Shape memory film can be used as label substrates or face stock for anti ...

8. 3D composites - Wikipedia

   en.wikipedia.org/wiki/3D_composites

   12 The foam will collapse as temperature and pressure are increased, which allows the fibers to be slowly pushed into the lay-up. 3D reinforcement in regards to Z-pinning is necessary to introduce a mechanical link between the different plies of the composite lamina, this link being a stiff carbon fiber rod in Z-pinning. Z-pin (carbon fiber of ...

9. Fiber volume ratio - Wikipedia

   en.wikipedia.org/wiki/Fiber_volume_ratio

   Fiber volume ratio is an important mathematical element in composite engineering. Fiber volume ratio, or fiber volume fraction, is the percentage of fiber volume in the entire volume of a fiber-reinforced composite material. [1] When manufacturing polymer composites, fibers are impregnated with resin.
