Poseidon Team “Trireme” Project “Little Whale” Project

Who we are… “POSEIDON” is a student team representing the Technological Educational Institute of Piraeus in the Shell Eco Marathon Students are challenged to design, build and optimize ultra-energy efficient vehicles. The main goal is to reduce energy losses to a minimum Projects are supported by sponsors and research funds

Trireme Project (1/3)“Trireme” was designed and built bythe team members inside the instituteand machine shops.Best result:528 Km/KWhcorresponding to approx.:5.000 Km/lt gas

Trireme +Trireme+ is the Trireme vehicle with the following improvements :  Vehicle’s weight reduced from 49k to 38.5k  Create new battery pack and charger

Composite Materials / Chassis We intent to manufacture the monocoque chassis using aerospace prepreg carbon fiber. The manufacturing process will take place at the Piraeus University of Applied Science and the Hellenic Aerospace Industry's production facilities. The prepregs require high temperatures (180oC) and pressure for proper polymerization, setting high standards for the tools used. Usually metal moulds are used but are disproportionately expensive for prototyping.

Manufacturing Process

Master Model The master model (plug) will be machined by a 5-axis FOOKE CNC mill using SikaBlock® 680 stacked in a designed pattern as to reduce material waste.Stacking pattern Master model

Moulds (1/2) The master model parts will be fitted on machined supports and the mould will be derived using Low Temperature Moulding prepregs (LTM).Master model Master model
