Does anyone have an equation for the resultant density of the composite materials? Having a look around the internet and I can't find anything, there was this one website that gave me a step-by-step but the answers did not match (sciencing.com)
Let A, B, C be finite sets such that A and B have the same number of elements, that is, |A| = |B|. Let f : A → B and g : B → C be functions.
(a) Suppose f is one-to-one. Show that f is onto.
(b) Suppose g ◦ f is one-to-one. Show that g is one-to-one.
Hello everyone, nice to be here.
I am going to calculate the young modulus of 3 layers of carbon fiber laminar composite
1st: 12K plain wave carbon fiber in 0 degree
2nd:3K till wave carbon fiber in 45deg
3rd:12K plain wave carbon fiber in 0 degree
How can I approach to calculate...
So, I'm a bit confused. The thing is, basically, all elementary functions are of the form ƒ:ℝ→ℝ. So the domain is ℝ and so is the codomain. However, if we have a function ƒ:ℝ→ℝ, given with f(x) = √x, it's domain is now x≥0. So, is the domain of this function ℝ or [0,+∞>?
Also, let's say we have...
I ran a test on an industrial composite of 30% glass-filled nylon 6, and my melting temperature peak is too low. The range was from -30 C to 275 C. Why could this be happening? Should I suspect the sample pan?
Given a composites tube made up of +45 layup. The tube is subjected to positive torque. Suggest a new layup that will improve the strength of the tube when subject to clockwise and anti-clockwise torque. Motivate your choice.
The Attempt at a Solution...
a)Describe a potential laminate lay-up that would exhibit high shear stiffness
b)Describe a potential laminate lay-up that would exhibit a low poissons ratio
The Attempt at a Solution
a) is a unidirectional lay-up in the direction of the shear force best?
b) an evenly layup...
Hi, I am looking for some guidance on a problem I am trying to solve on laminate analysis.
This is a flat laminate (9 plies with a thickness of 0.125mm) of unidirectional carbon fibre reinforced plastic with a stacking sequence of:
Ply properties are as follows:
I'm looking for a gas (hopefully one that is readily available) that will absorb Nd:YAG laser radiation at 1064 nm. The purpose is to heat the gas to transmit heat into a glass fiber composite which normally does not absorb IR light.
I'm analyzing a composite leaf spring using ANSYS APDL, the leaf spring has a thickness of 12mm, and since it is a composite material, it is composed of many plies, I'm assuming the ply thickness to be 0.125mm. I imported the geometry as a Parasolid x_t. And the element type I used is...
I am doing a High Velocity Impact testing using a gas gun
I have to figure out
a) is my test running well and I am not getting any reflection?
Please correct me or help in calculating if I am wrong at any point. I guess, I can figure out by calculating the time required for the...
I am a part C Mechanical Engineering student and have been undertaking a project investigating the strain sensitivity of a particular glass filled composite.
From my quasi-static results, the stress-strain curves seem to be reasonable and match that of the mechanical material properties...
Hi, I was tasked to design a composite material that will undergo a 3 point bending test. Maximum deflection will be of 15mm and a maximum load of 5kN. The scope of this task is not to prevent failure but to analyse the composite and learn from the design process. Nonetheless the composite...
I am trying to figure out what stresses in different planes mean physically for composite laminates.
Say S stands for stress then
SXX SYY SZZ would be longitudinal/axial stresses in respective Axes. (If we take the laminates to be in XY plane, failure stress SZZ would be equal to...
We can find differential of alloy and composite. MMC is came from 2 differential of metal, one from it aren't melting same as producing alloy. but there are might produce new reaction. ex: C with Fe, the name is carbon steel. the nano-composite just too, but the particle aren't big, and the size...
I am working on a project in which we need to shield an electrical field with a heavy 1 MHz component, at the same time, sparing the magnetic field as much as we can. With our limited knowledge, we came to the conclusion that a material with 10 kOhm conductivity would do this...
