  • C.A.P.E. - The Center for Advanced Product Evaluation

    Several years ago, A.E.D., partnering with Spike Chassis and CAPE – The Center for Advanced Product Evaluation, set out to crash test a sprint car to provide real world scenarios of what happens during an extreme sprint car crash.

    A.E.D., Spike and CAPE performed 3 separate crash tests and a drop test on three different chassis. Spike Chassis built three cars with 4130 chrome moly (chromoly) tube supplied by A.E.D., and produced by Webco Industries (USA).

    These tests have allowed us to collect data and analyze many different details such as the chassis upper roll cage structure, impact values, how 4130 holds up under these extreme crash conditions, and how the human body responds and stretches under these types of loads. The data collected has also been used to perform further testing on design and different materials used in building of chassis in simulators, as well as creating stepping stones for numerous academic programs to study structures and safety engineering.

  • Certificate of Conformance (or Compliance)

    This is a document used in commerce or business in which a competent authority indicates that the product or service that is supplied meets the required specifications. May also be called a Certificate of Conformity. All may be abbreviated as a “C of C,” and may be used interchangeably.

  • Clamp Die

    Tool to hold fast the tube end that is being bent. These have various clamp lengths which determine how close we can bend two bends next to each other.

  • CLR

    CENTER LINE RADIUS - This is a common term in the tubing industry, and it is used to describe the radius of a bend. The CLR is the radius down the center of the tube. Other fabrication processes use Outside or Inside Radius like Sheet Metal Fabrication. Again, tubing uses the center of the material. Most common as a description on round tubes (Always review drawings very carefully).

  • Commercial Quality Material

    This is material produced for general purpose applications. A particular grade of Commercial Quality (CQ) metal will have the same chemistry as the same grade that is considered “Aircraft Quality,” however no special testing has been performed for certification in aircraft or aerospace uses. Most CQ materials will be defined with ASTM or similar standards.
