Joining of carbon fibre reinforced polymer (CFRP)

2017/10/1During welding of CFRPs to CFRPs and to metals, laser can be used as a heat source. It is a non-contact procedure which requires the entrance to the weld zone from one side of the parts being welded. Two types of processes consisting of laser deep.

Flexible graphite as a heating element

2002/1/1Flexible graphite is an effective heating element. It provides temperatures up to 980 C (though burn-off occurs in air at 980 C), response half-time down to 4 s, and heat output at 60 s up to 5600 J.The electrical energy for heating by 1 C is 1–2 J in the initial portion of rapid temperature rise.

Review in preparation and application of nickel

The nickel-coated graphite composite powder (NCG) with graphite as the matrix and metallic nickel as the outer shell is a composite powder with a "core-shell" structure . Graphite is a typical carbon-based material that has the advantages of being lightweight and having high electrical conductivity, natural crystal structure, a certain diameter-to-thickness ratio, and good stability.

Arc lamp

An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light.[1] It was widely used starting in the 1870s for street and

Lithium aluminium hydride

Lithium aluminum hydride appears as a white powder that turns gray on standing. If spread out over a large flat combustible surface, friction can cause ignition. Used to make other chemicals, as a polymerization catalyst, as a hydrogen source, and as a propellant.

Borosilicate glass

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 10−6 K−1 at 20 C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal
