Natural fibers are gaining the interest of scientist and engineering in packaging, low cost housing and other general applications. In the present study, adhesive tensile and moisture absorption properties of randomly distributed areca fibre and maize powder reinforced urea formaldehyde composites has been investigated. Composites were prepared by hydraulic hot press at 150C and 100 bar pressur...

The accurate and reliable numerical approximation of wave propagation is of fundamental importance to the simulation of acoustic, electromagnetic and elastic phenomena. In mechanical engineering, advanced composites such as carbon fibre reinforced polymer have become one of the most promising materials to build light-weight structures for several fields of application, for instance in aerospace...

Optimization of the stress transfer capability of the fibre-matrix interphase region is critical to achieving the required performance level in thermoplastic matrix composites. Despite the ever increasing diversity of the reinforcements available for polymer composites, glass fibres still account for 95% of fibre reinforcements used in the composites industry, primarily due to of their highly a...

Glass reinforced thermosetting composite materials are now widely usUUed in building and construction applications. However, the adoption of Boron and Kevlar based composite materials in this industry has been very slow, and the main reasons are lack of previous experiences to assess the durability of such composite products and understanding of their properties by designers. In order to fill t...

The options for the fibre reinforcement of polymer matrix composites cover a range from short-fibre chopped strand mat, through woven fabric to unidirectional pre-impregnated (prepreg) reinforcements. The modelling of such materials may be simplified by assumptions such as perfect regular packing of fibres and the total absence of fibre waviness. However, these and other features such as the cr...

the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...

A polycyclic fatigue damage model for short glass fibre reinforced thermoplastics is developed and implemented into ABAQUS FE code using UMAT subroutine. The MNL model is introduced here in terms of damage rates: ( ) ) ( 2 0 1 2 0 2 1 2 1 1 ) ( ) ( N ij ij ij ij ij ij ij ij ij ij ij e E E N d d λ β ε γ ε β β α − −       +       + = ∂ ∂ = & (1) Where N is the number of cycles. αij, β...

Recent interest in the utilisation of greener materials has reinitiated the interest in natural fibres and/or fibrils as reinforcement for polymers. However, such bio-based composites often exhibit properties that fall short of expectations due to (i) inadequate processing conditions, resulting in filler agglomeration and poor filler dispersion within the matrix, (ii) variations in natural fibr...
