  2. 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.

  3. J-B Weld - Wikipedia

    en.wikipedia.org/wiki/J-B_Weld

    J-B Weld is a two-part epoxy adhesive (or filler) that can withstand high-temperature environments. J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9]

  4. Fiberglass - Wikipedia

    en.wikipedia.org/wiki/Fiberglass

    Resin—typically a 2-part thermoset polyester, vinyl, or epoxy—is mixed with its hardener and applied to the surface. Sheets of fiberglass matting are laid into the mold, then more resin mixture is added using a brush or roller. The material must conform to the mold, and air must not be trapped between the fiberglass and the mold.

  5. FR-4 - Wikipedia

    en.wikipedia.org/wiki/FR-4

    FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The ...

    The ratio, is called the "critical aspect ratio". It increases with composite strain ε c {\displaystyle \varepsilon _{c}} . For the mid-point of a fiber to be stressed to the equal-strain condition at composite fracture, its length must be at least d f σ f t e n s i l e / 2 τ m y {\displaystyle d_{f}\sigma _{f}^{tensile}/2\tau _{my}} .

  7. Fiberglass spray lay-up process - Wikipedia

    en.wikipedia.org/wiki/Fiberglass_spray_lay-up...

    The difference comes from the application of the fibre and resin material to the mould. Spray-up is an open-moulding composites fabrication process where resin and reinforcements are sprayed onto a reusable mould. The resin and glass may be applied separately or simultaneously "chopped" in a combined stream from a chopper gun.

  8. Matrix (composite) - Wikipedia

    en.wikipedia.org/wiki/Matrix_(composite)

    The price of the vinyl ester resin is similar to that of the polyester resin. It utilizes the same hardeners as polyester resin (at a similar mix ratio). It doesn't degrade much over time, when compared to polyester resin, and is more flexible. Generally, vinyl ester resin is considered as fuel resistant.

  9. Phenol formaldehyde resin - Wikipedia

    en.wikipedia.org/wiki/Phenol_formaldehyde_resin

    Obtained polymer is thermoplastic and require a curing agent or hardener to form a thermoset. Hexamethylenetetramine is a hardener added to crosslink novolac. At a temperature greater than 90 °C, it forms methylene and dimethylene amino bridges. Resoles can also be used as a curing agent (hardener) for novolac resins.
