The carbon fiber composites failed in a brittle mode. Standard test methods for notched bar impact testing of metallic materials. Analisys of the gelation process of suspension pvc resins and.

Several microstructural analysis techniques were used: The energy absorbed to fracture the composites had an inverse correlation to the fibres’ elastic modulus. Nonlinear finite element modeling of charpy impact test. The analysis of the fracture surfaces showed that for the glass fiber composites, the failure is controlled by a coupled mechanism of shear along the fiber-matrix interface and tension transverse to the fibers.

Challenge In order to measure the toughness of a material using a Charpy impact test, it is necessary to prepare specimens from the material or product of interest. In this paper some interesting results of charpy impact tests are presented. Repositorio da producao cientifica e intelectual da unicamp.

The aramid composites could not be modelled by the elastic analysis performed.

Instron – ASTM E23 A ISO Charpy Impact Testing Sub-Size Specimens – Instron

A typical Charpy test requires the notched metal specimen to rest on supports at each end in a horizontal fashion while coming in contact with vertical anvils adjacent to the supports. These smaller specimens require supports that raise the specimen higher in order to keep it centered with the striker and anvils. The elastic model underestimates the energy absorbed by the glass fiber composites, but the difference between the experimental and calculated values is not high.
