The CORD automobile. An automotive classic.

 

	Sound deadening mat StoneRod sound deadening mat can be cut and slid into the outer silencer casing. It is wrapped around the perforated exhaust pipe, which passes through the inside of the case. The mat is made from roving that is converted into mat by needle punching. The mat has excellent resistance to exhaust gas chemicals and is unaffected by the heat of the gas.
	Sound deadening roving StoneRod silencer roving is made from textured roving. The fibre is heat resistant and also has excellent sound deadening qualities. It is more expensive that glassfibre but its ability to withstand chemical attack, added to its better sound absorption qualities, makes it the choice in high performance silencers.
	Fibre exhaust wrap Wrapping of exhaust manifolds and turbo pipes has become a normal part of high performance motor vehicles. The wrap maintains the heat in the exhaust system, and improves the gas flow. At the same time it assists in reducing under-bonnet temperatures.
	Woven tape StoneRod taps is excellent for use in thermal insulation. Heat insulating braided tapes can be wrapped around turbo pipes, exhaust manifolds and pipes. Turbo and catalytic converters operate at maximum efficiency, when correct operating temperatures are maintained. Tape wrapped pipes can be coated with additional insulating coatings if required.
	Woven sleeves The StoneRod woven sleeves are made by weaving continuous basalt fibre. It can be processed & surface treated when applied. Its high temperature resistance, chemical-corrosion resistance make it suitable for sliding over exhaust pipes. Exhaust pipes covered with StoneRod woven sleeves will maintain heat after shut-down of the motor. This heat will vaporise any moisture that would normally aid and abet corrosion.
	Woven insulation sleeves Smaller diameter Stonerod woven sleeves can also be used to wrap electrical harnesses. The harnesses will be electrically isolated and will also be insulated from the engine compartment heat generation. The sleeves were extensively used in armoured car manufacture, during the Cold War.
	StoneRod fibre mat StoneRod fibre mat is able to withstand temperatures up to 750 - 800°C. The mat/felt is manufactured in various thicknesses to suit numerous application types. It can be used to protect from fire and heat degradation. Uses include insulation heat shields, turbos, and as sound and heat isolation in body panels.
	Needle punched mat/felt StoneRod mat/felt can be sandwiched in body panels, where it will reduce road noise. StoneRod felt has very low thermal conductivity and can withstand continuous temperatures from -200°C to +700°C. It has an excellent ability to drape and can conform to irregular surfaces and shapes. It can be wrapped around fuel tanks to minimise temperature increases, which lead to evaporation.
	StoneRod twill fabric StoneRod basalt twill fabric is used in fibre reinforced composites. The material can be used as the heavy reinforcement material in automotive body parts where its inherent strength provides rigidity to the composites. This high strength fabric provides rigidity and strength.
	Stonerod fibre veil Fibre veil materials are used as surfacing tissue for composite parts. The fibres are highly corrosion resistant, provide excellent conformability and wet out. Basalt veil can replace glass-fibre veil in fibre-reinforced-plastics (FRP), giving enhanced strength to the composites.
	Tesla S body parts "The Tesla car body can be made of basalt fibre," said LARTE, "a very light material". The new entire external tuning package weighs less than the original car parts. The original weight is almost 33 pounds (15 kg) and the new kit only about 29 pounds (13.182 kg). The LARTE basalt alternatives have high impact strength and shock-absorbing characteristics. Basalt fibre has a high strength to weight ratio, which makes the outer parts of the vehicle (bumpers, spoilers, etc.) stronger and lighter. With electricals vehicles, weight saving is a premium factor.
	Short chopped fibre Chopped basalt fibre is used in friction materials such as clutch facings, brake linings and brake pads, and can perform at higher temperatures. They are resistant to chemically aggressive conditions, with increased shock resistance, low water absorbency, and extended wear resistance. The material far surpasses the asbestos type materials previously used is friction materials. They have been proved in assessments for performance and longevity.
	Fibre reinforced linings Clutches have developed in recent years. However, the most used automotive clutch system still comprises of a flywheel with a machined facing, a clutch plate with double sided friction linings, a pressure plate that applies / releases pressure on the clutch plate assembly, and a thrust bearing mechanism that activates the pressure plate through fingers that operate the clutch system.
	Disc brake Disc brakes have been in operation for a number of years. The system comprises of a rotating disc that is mounted onto the wheel hub, and a calliper system mounted over it. In the calliper, hydraulically activated pistons are mounted. Between the spinning disk and the securely anchored calliper, disc pads are fitted. When the brake pedal is pushed, hydraulic fluid from a master cylinder forces the pistons outward, and squeezes the disc pad against the rotating disc.
	Hard-wearing replaceable pads StoneRod short length fine fibre materials provide excellent reinforcement to the abrasion resistant polymers. The fibre gives enhanced abrasion resistance due to its volcanic rock origin. The clamping motion generates high temperatures in both the friction material and the rotating disc. Disc friction materials must be able to withstand both the friction and the elevated heat generation.
	Drum brake system The drum brake system is still extensively used. The brake drums/wheel hubs are mounted on the axle, and rotate together with the wheel. The brake drum has a machined metal face on the inner periphery. Brake shoes are anchored inside the drum, and have a double actioned hydraulic cylinder fitted with two moveable pistons. Hydraulic pressure forces the pistons apart, causing the abrasive resistant brake shoes to be forced into contact with the inside of the drum.
	Moulded brake linings Drum brakes comprise of a drum, mounted on the wheel hub that has a machined surface against which the brake shoes apply force. Brake linings can be riveted or adhesive bonded to the brake shoe. They can be made in lengths or in pre-formed shapes. High temperatures are generated during braking and the moulded brake linings withstand repeated heating and retardation forces. The linings are an exotic blend of fillers, polymers and fibre.
