A comparison of the effect of nano clay addition on microstructures and mechanical properties of epoxy and polyester reinforced glass/sisal hybrid polymer composites

Abstract: In the present study, a comparison has been made between the mechanical properties of polyester and epoxy matrices reinforced Sisal/S-Glass, and also the effects of nano clay addition have been studied. For fabrication of composites, Glass/Sisal fibers are reinforced with Polyester and Epoxy with various wt% of nano clay. These composites are fabricated through the hand lay-up technique. Various wt% of nano clay are 2, 4, 6 wt%, and the stacking sequence of fibers are GSSG (S-Glass/Sisal/Sisal/S-Glass). The variations of strengths among the polyester/epoxy are also studied and examined. In Epoxy/GSSG reinforced NC composites compared with 0–4 wt% tensile strength increased by 18%. Polyester/GSSG reinforced NC composites tensile strength increased by 16%, and in Epoxy/GSSG reinforced NC composites compared with 0–2 wt% flexural strength increased by 16%. Polyester/GSSG reinforced NC composites tensile strength increased by 24%. The microstructural analysis has been carried out on the fractured samples, which indicated brittle failure of the fiber and fiber pull-outs. This conclusion confirms the proposed novel laminates fitness for possible usage in structural applications in the aerospace sector.

Method for manufacturing sisal hemp soap

Abstract: The invention provides a method for producing sisal soap, which comprises: performing soda boiling on sisal and obtaining sisal fibers and ticogenin genuine soap; utilizing residual aqueous alkali and grease for saponification to prepare fused genuine soap; and utilizing the fused genuine soap to prepare the soap. Because the prepared soap contains ticogenin and grease genuine soap, the prepared soap has the characteristics of good washing effect and non-pollution. Simultaneously, the prepared soap has the characteristics of reducing application of other foaming agent and maintaining a natural pigment, also has the characteristics of realizing preparation of the fibers and the soap by a one-step method, fully utilizing heat energy, improving the preparation speed of the sisal fibers and reducing wastewater emission, and is suitable to be applied to production of washing articles.

Experiments with pipelining parallelism in SISAL

Abstract: Streams in functional languages allow clear description of many problems which can be expressed in terms of successive transformations of data-they provide declarative expression of software pipelining. SISAL is a functional language with predominantly strict semantics but including non-strict streams to allow expression of pipelined parallelism, processing of notionally infinite streams, and communication between program modules. The authors discuss an implementation, using buffered streams, of SISAL streams on conventional multiprocessors, and programming techniques for some stream problems-a circuit simulation, prime number sieve and a text processor. They present experimental results showing the effect of various buffering parameters, and useful speedup. They point out some potential problems with the SISAL view of streams. >
