2013-05-21 Composite Materials - Composite Modelling:

Your doubts are explained in great detail in this book:  http://www.crcpress.com/product/isbn/9781466516618    But, a short answer:  - 3D solid, computationally very expensive. Use only for modeling details

2013-05-09 Composite Materials - fabrication of coir composite:

HI Vasant,    I would recommend using a lower viscosity resin, and matched die mouldning at a minimum to get your 10mm thick lamainate.  Lots of pressure (a press, or light mechanical press and vacuum

2013-05-08 Composite Materials - fabricatio of coir composite:

Hi Vasant,    So to get 10% fibre fraction, thats 90 grams of resin to 10 grams of fibre.  To get 20% fibre fraction, thats 80 grams of resin to 20gms of fibre.  I'm sure you get the idea there.    I find

2013-05-06 Composite Materials - Safety factor for composite structures:

This is a complex question, if I want to answer it in detail. To begin, if you do Nastran on Aluminum, how do you evaluate the safety factor? You compute the von Mises stress. Well, that is a failure criterion

2013-04-30 Composite Materials - little clarification on testing:

If you are doing the test for someone that requires you to follow the standard, for example for aircraft certification, then you have no choice but to use exactly the dimensions in the standard unless
