The present invention is a system for automatically testing and providing notification of an efficacy failure of an electrostatic discharge (ESD) device or devices. The system includes testing circuitry for testing the efficacy of one or more ESD devices, a memory for storing ESD device testing protocol, ESD device test results, employee identification information, e-mail messaging software, and interface connection software, an internet interface, and a processor for controlling the testing circuitry in accordance with the executed process steps of the ESD device testing protocol and for controlling the storing of the ESD device test results in memory, wherein the processor automatically provides email notification of efficacy failure of an ESD device by collecting and formatting an ESD device test result into an e-mail message using the stored e-mail messaging software and forwarding the e-mail through the internet interface using the internet connection software.

The subject invention relates to a toughened epoxy matrix formulation useful as a prepreg for fiber reinforcements comprising at least two epoxy components, an amine hardener and about 10%-25% of a micropulverized polyimide thermoplastic having a molecular weight of from about 20,000 to about 100,000 and Tg of at least about 220. degree. C. The invention further relates to a process for preparing a toughened epoxy matrix formulation comprising: a. preheating a blend of at least two epoxy compounds to a temperature of about 130. degree. F. to about 140. degree. F. ; b. blending into the epoxy blend from step (a) a micropulverized polyimide thermoplastic; c. mixing the blend of epoxy and thermoplastic at a temperature of about 110. degree. F. to about 130. degree. F. ; and d.
