Abstract:

Composite materials mainly integrate two or more materials to get a combined property of individual materials. One of the considerable types of composites is structurally insulated panels (SIP).
This research paper intended to investigate and analyze structural panel composite using Bagasse reinforced PET and polyester resin with bagasse composite as a facing material. It extruded polystyrene as an insulation foam core. After the juice is extracted from sugarcane, the sugarcane bagasse is prepared with 1.2 and 1.5 cm length and 1 mm width, and then washed using pressurized water for 1 hour and made dried at normal temperature for one day. It was then treated with 0.3 and 5% wt of NaOH solution for 2, 4, and 12 hours with a 15:1 solution to bagasse ratio at 60oC. After its alkaline treatment, it was washed until the NaOH is completely removed. It is then dried in the oven for 6 hours and after 24 hours of room temperature drying. An optical microscope finally observes the samples before blending.
The matrices used are polyester resin and recycled PET. The recycling is done mechanically. Different types of PET bottles were collected and cut into pieces. A hot wash-down with 2% NaOH solution and using a detergent at 80oC then finally washed only by cold water. Dried and 60-gram melt at 246oc, 250oc, 300oc, and 380ocaccording to the DSC result. A furnace and hot Stirrer is used to melt the samples. The sample at the temperature of 380oc is melted into some form in hot and Stirrer plates. The samples in the furnace melted at the temperature of 265oc. The fiber could not withstand the melting temperature of the PET. This is due to a lack of physical property for facing. Its hardness is measured and found to be 100Hv. The other sample is the polystyrene resin matrix. This is found to be highly compatible with the sugarcane bagasse. 100 grams of Bagasse is added to 50-gram polyester raised with 1ml of catalyst and compressed. Waited until it cures about 12 hours and characterized. Its hardness was found to be 180 HV. The structural insulated panel is prepared using three facing materials, recycled PET matrix, and a composite of polyester risen and sugarcane bagasse. In both cases, the insulated foam core is extruded polystyrene. Wood fix glue is used as an additive and compressed with pressure.
