What is this 'composite' you are referring to? There are so many, and I would think that in your part of the country you would not be concerned.

Be careful with these.  You might have one that could work but here is a short and incomplete list of my concerns:

  anti bug chemicals, most are toxic to humans

  plactic impregnation so you may not know its type or best glues to use.  Industrial and construction glues are recommended but these are not designed  for the fine work we do on models.

  glues used in the manufacturing of the stuff.  For example, formaldihyde and urathane glues are toxic to us, as are expoxies and resins.

 

Thus, sanding and cutting this material would be hazardous.  These materials are designed to withstand the harsh elements mother nature throws at us.

 

Stay safe and have fun.

Yes, there are warnings about burning the materials and toxic releases. But the same as plastics.   I was just wondering about the material.

Pardon my timely post on this old topic:

 

The leading source for these engineered wood products is USDA Forest Products Laboratories. A free detailed downloadable book is available at: http://www.fpl.fs.fed.us/products/publications/several_pubs.php?grouping_id=100&header_id=p

I suggest downloading it if have any questions regarding wood and engineered wood and related products i.e. adhesives.

Majority of these new products are aimed at the construction industry and you have likely seen them in new home and apartment construction. As with any engineered materials there are advantages and disadvantages depending on application. The FPL book will guide you through each topic promoting reader understanding.

One item which I found very interesting for ultralight wing spars is GLULAM (glue laminated wood) if properly done can increase strength by 25% without any weight penalty.
