Is There a Type of Wood Strong Enough and Affordable for Building Car Frames?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using wood as a material for building small passenger car frames. Participants agree that while wood, specifically ash, has been successfully used in the past by manufacturers like Morgan for sports cars, it does not match the strength-to-weight ratios of modern materials such as aluminum and carbon steel. The consensus is that no wood can currently provide a stronger and cheaper alternative for car frames, primarily due to safety concerns and energy absorption capabilities in collisions.

PREREQUISITES
  • Understanding of material properties, specifically strength-to-weight ratios
  • Knowledge of automotive safety standards and energy absorption in collisions
  • Familiarity with traditional car manufacturing techniques, particularly the use of wood
  • Awareness of modern materials used in automotive design, such as aluminum and polymers
NEXT STEPS
  • Research the properties of ash wood in automotive applications
  • Explore advancements in polymer materials for vehicle safety and design
  • Investigate historical examples of wood use in car manufacturing, focusing on Morgan cars
  • Study the impact of material choice on vehicle performance and safety in collisions
USEFUL FOR

Automotive engineers, material scientists, and enthusiasts interested in the intersection of traditional materials and modern automotive design.

Can we built the small passenger car body using ANY WOOD which is STRONGER and CHEAPER?
If so, name the wood.

Tell us your thoughts first. What is the context? Are you looking to do a design project?
 
There are no woods that come close to the strength/weight ratios of current materials in cars such as aluminum, stainless steel, or even plain carbon steel.
 
Morgan have been doing a good job making sports cars using ash frames for one hundred years. They're still good by today's standards.

Let's be honest- the Morgan cars are bought for their styling, not because of their competitive performance or impressive Ash frame technology...

Nonsense, I've been successfully campaigning one this season and don't even like the look of the thing! Although if by "competitive" you mean "with other marques" then you may have a point. Still, faster round a track than lots of stuff made solely from 'modern' materials!

Seriously though, wooden cars can still be made to go 200+ mph

With you on that, pal. It's sort of along the same line as major-league baseball players using ash or maple bats as opposed to metal. I don't know whether or not there is a specific cut-off point from a material aspect, but a wooden bat just puts so much "feel" into the hit that it is bound to go farther/faster if only because of the son's emerging sense of confidence.

edit: Upon re-reading this, I noticed that I did not express myself properly. There are a lot of youngsters on-board, who are entitled to a "clueless" childhood. "Son's" was not meant to be a diminutive address.

realize that these cars won't absorb as much energy from collisions like a metal does. malleability of metals are critical for this. second imagine being struck by lightning. specific metal is used to separate charges

I respectfully disagree with that. Although I have always been a "Detroit Iron" driver, and have no use whatsoever for "rice rockets", polymers are a lot easier to tailor to specific purposes such as crush absorption.

Lightning struck is so rare it can be safely ignored as a problem.

If it was you in the car you wouldn't be saying that now would you.

Metal-bodied cars work quite well as a Faraday cage. Next...

How many cases of cars struck by lightning have you witnessed? Heard of? Do you have a reliable statistic showing it is frequent enough to make metal cars safer in the storm?

I suppose when you sit is a vehicle that is hit by meteorite M1A1 Abrams is safer than my Opel Astra, but I am not going to buy a tank because of that. Not many meteorites striking cars in my area.

Whoah, it was odmart that brought that cobblers up!

The OP's original question was if a "car's body frame" could be made out of a wood which is stronger and cheaper. In my opinion, the answer is still "no."

He must have edited it mighty quickly. There was no mention of "frame" in it by the time I read it.
