How much would Trex composite decking cost per square foot?

My husband is a DIY’er and wants to replace our deck with this. I never get to see the Home Depot bill. I might faint if I did considering the time he spends in there…

How much would it cost for composite decking in materials? Thanks.

the Home Depot site says $19.97 per 8 ft board (5.5 inches wide & 1 inch thick).

Do you trust composite materials, such as carbon fibre or other laminate composites from a safety aspect?


Yes.

F1 racing cars are built using a composite materials. What substances are combined in this material and why?

Thank you.

Carbon Fibre is the most prominent material in a F1 car – this is because carbon fibre absorbs a lot of the energy in a crash and breaks apart – leaving the driver in the monocoque nice and safe.

I would like to know the various "composites" softwares available?

I’m interested in performing a impact analysis on sandwich composites & Laminated Composites.,

Pls let me know which software will help me in simulating these capabilities

That’s a tough one. You’ll need something like FiberSIM coupled with LS Dyna. It’s over $50,000 for the software licenses alone.

It would be far cheaper just to fire projectiles at test samples, and you’d get more accurate results.

What are the advantages of using carbon composites in skis and ski poles?

I’m struggling to find properties of carbon composites that would mean they were useful for skis. I’m also looking for examples of carbon composites often used in skis.

Light weight and high strength, together with skis and ski poles providing ideally simple geometry for carbon fibre application.

Price-point tennis rackets?

I posted a question a few days ago about a Wilson BLX Fierce (FX), but nobody knew anything about it.
SInce then, I have heard of something called a ‘price-point’ racket, which I believe the Fierce BLX may be. Other examples probably include things like Head raptor, some Prince EXO3 hybrids and Babolat E-sense/XS/Pulsion.

I am worried that these rackets may not be what they claim to be. There must be some reason why the price is lower (although in some cases not by much!), is this because the material is cheaper (e.g. Graphite composite or even aluminium) when it claims to be full graphite, does not play well etc.?

Basically any views on this matter are welcome. I am on a budget and cannot dish out £100+ for a proper pro racket. Hence I need to know as much as possible about the rackets that ARE in my price range. Cheers

I would call things like some of those ‘mid-level’ frames. They aren’t your super-cheap frames, but they aren’t anything too special, either.

Basically, from Wilson, there are four basic models that would be considered ‘high-end’: Six-One, Pro, Tour, Blade. There are a variety of frames based off each of these. For example, there is the Blade Tour, and the Blade 98.

Then you have things like the BLX Pro Team FX. This is more of a marketing ploy than anything. People see a pro who uses a particular frame, but know they can’t really handle the actual frame the pro uses. So what does Wilson do? Make something that looks nearly identical, but with beginner to tweener specs instead. These frames tend to be more intermediate level. They aren’t spectacular in one area.

There are also some just straight-up beginner’s frames. These are the giant, light-weight ones. These actually tend to be higher in price, because many beginner’s believe that large and light is better (and it probably is for them). That, and they think that because that they paid $270 for their Wilson BLX Cierzo Two, that it will surely improve their game.

As for worrying that the frames aren’t ‘what they claim to be’, don’t worry, they are. That would be false advertising and lead to a lot of problems. If they say they are 100% graphite, they are.

Now, if you want to get a good deal on a quality frame, which seems the case, check out the sale sections from various online stores.

This is an american-based site, but I do know they ship internationally. These are all frames that would have been $200 back in the day, but have since been replaced by a new line of frames. There are some very good deals in there on some great frames.

what is a better first shotgun a benelli super nova composite stock or an 870 remington wood stock?

i am getting into hunting probably everything in california and im deciding which shotgun i should get my budget is about 400 and i cant decide between these two and also i was concidering a mossberg or a weatherby HELP!!!!

Hello,
the Remington is the best way to go.
highly reliable. and I have heard some bad things of the Benelli.

How do you prove by contradiction that there are infinitely many composites?


Here’s a rough idea

Suppose that there are a finite number of composites.
Consider C = {set of finite composite numbers}.
Let x be the largest of all composite numbers in set C.
Let k = a natural number, k >1.
Then let n = k * x.
n is composite, yet n is not in C.
Contradiction.

There are infinitely many composites.

Which is the better of the 105 spec Carbon Road Bikes.?

What would be the better Road Bike. 1/ Cannondale Synapse Carbon 105 2011 with RS10 wheels,
2/Giant TCR Composite 2 2011 or 3/ Specialized Roubaix Carbon Comp SL2 2011.

They are all nice bikes and have the same components get the one that feels the best.
