Meet the Instructor

Hi all!

Welcome to the first introductory course of composite materials provided by Navalapp.

My name is German Pacheco, and I will be in charge of giving you all the knowledge related to this peculiar and so fascinating material.

But first, I would like to introduce myself so you can get to know me a bit more.

I’m a Naval architect from Argentina with more than 15 years of experience in the composite field. I’m currently working in Australia as a senior design engineer for a growing drone’s development company, where I’m in charge of the design and building procedures for the different VTOL aircrafts, all made in composite materials, from the external shape to the internal structure.

I started to learn how to work with these materials in the really early age. I managed the construction of several boats from 30 to 100ft overall length. Even though my expertise is largely in the naval field, I have also worked on several projects developing and producing parts for different industries, such as the agro and aerospace.

For those interested, this course will be divided into modules or stages where the participants will be provided with all the principles and theory that involve the composite materials, understand what they are, their components, and what they can be used for. We will run through the different manufacturing processes and materials, while I will share my own experience as a boat builder as well as a composite designer.

If you want to start to be part of this world and learn about these materials and how to use them, this course is for you!

It will be a pleasure to share my knowledge.

I look forward to having you all on board!
